996/GT3 race car build
 

I searched all over the country to locate a low mile, clean, well taken care of 996 GT3. I chose to build a full race car out of a 2004 996/GT3. The GT3 has steel synchros and the all important dry sumped engine. I looked at several cup cars, but decided that cup cars require a tremendous amount of maintenance versus converting a street car into a race car.

I decided to hire Global Motorsports Group (GMG) to help with the build. They have experienced tremendous success racing Porsches in multiple series. I will document the build of this car from day one.

I hope you enjoy the documented build process.

Here is the car before tear down................:surr:

GT3

This cage is an EXACT replica of a Porsche GT3 Cup car. Except, I have modified the driver side doors bars for safety, and I have attached the cage to the front shock towers. Other than that, the cage is EXACTLY as a Cup Car cage comes from the Porsche factory.

Wow. Like that cage.

Holy Crap you are serious. What will it weigh when you're done vs. a cup car?

nice.
beside cage, what else you put on it?
what's the total build time? 3 weeks to race?

The car will be a tad heavier than a CUP CAR.....
It will have carbon doors, lexan windows and carbon decklid and wing.

With lightweight wheels, it should weight in around 2800
with a 1/4 tank of fuel.

what class will you be racing in?

I will be running this car in POC, PCA, World Challenge, and NASA. in the GTS class. (Power to weight)


GMG will be supporting the car at all of the events.

Carbon doors
Decklid
Lexan windows

I hope to have this ready for the tribute to Le Mans at Fontana, CA

awesome build :thumbup: that is some excellent work on the cage; great pics; a great project; good luck.

what brand of CF doors?
Porsche motorsport or getty or gt or.....

YOU LUCKY SOB.......Incredible....4 more yrs and I get my gt3. Love it great build!!!!!!!!!!!!!!!!

I love how the Nascar bars are done, super slick! We cut some of the door jam out of my car but this way is even better!

Subscribed!

What class in PCA?

:icon107: dont know in PCA.......they need to switch over to the power to weight formula like POC and NASA.

In NASA and POC.....I will run in....

GTS3 or GTS4 depending on where it is most competitive with car count.

I'm pretty sure it will be GTA in PCA. I looked into it when I wanted to go racing in my GT3 and was told GTA by multiple sources (scruts, rules, etc).

As far as NASA, sounds like you would be GTS4 or 5 depending on weight. I don't know anything about POC so I couldn't comment.

At 3050 lbs. with driver, I can run in GTS3 or GTS4. It will be close in GTS3 but I can always add ballast.

I will race the car where it is competitive and in a class with a high car count.

:jumper:

How are you going to run GTS3 at 3050 with driver? You'd have to dyno out at 277 just to be at the very top limit of GTS3. The GT3 will typically dyno in the 325-350 range which means you would have the weigh in the 3575-3850 range (with driver) to run GTS3. And this is all taking into account you'd run Dot-R tires not slicks.

The spec boxsters BARELY slot into GTS2 (and need ballast to do so) or they would run in GTS3. No way the GT3 is running in GTS3.

GTS-4....mmmmmm....maybe (and a big one). Thats a GTS-5 car.

GT3 between 8.51 lbs/HP and 11.00 lbs/HP

Slicks= 9.01 lbs/HP and 11.50 lbs/HP

GT4 between 11.51 lbs/HP and 14.50 lbs/HP
slicks= 11.51 lbs/HP and 15.00 lbs/HP


330 hp @ 3050= 9.24= GT3

:icon107:

Apples/oranges; his numbers are for POC not NASA...

I'm pretty sure you'll have more than 330rwhp with an open exhaust, modified air box, and a GIAC flash which is what GMG uses. We got that out of a 3.6 X51 recently. Regardless you'll never make GT4 without carrying Oprah onboard....

So your target should be to try and keep it in GT3 (my class) along with fellow GMG competitor Gary Tolar. GT2, the next level up w/POC, has all those worn out 6 and 7 cups along with the "Yellow Bee". Those cars are turning 1:22-1:23's at Willow Springs, and 1:43's at Cal Speedway. Tough crowd to break in with....

You should come out to Willow Springs May 1-2 and watch some of the races....

if yellow bee, cups are in GT2 for poc, i fear to ask what is in GT1?
big turbos and factory RSR?

Exactly.....

My 2 cents, went through a similar process with my GT3, weight with me in it is 3089, SAE dyno for NASA at 340 - puts me squarely in GTS4 but I could stand to loose ~170lbs. to maximize power/weight. I would have to add 700+ lbs to make GTS3.

NASA Guidance
DOT GTS4 -> 8.5 - 10.99 and GTS3 -> 11 - 14.49
Non-DOT GTS4 -> 9.0 - 11.99 and GTS3 -> 12 - 15.99

Calc can be found here: http://www.nasagts.com/rules/

Modified the main hoop and added a cross bar......now its off to paint

In PCA the class is GTA1, a good class with many cars to race with. You could also run as a GT4 class car.

Can't run GT4 in PCA as they don't have the hp/l modifier for the GT3. I already looked into that. It's GTA or make it compliant with the stock (J) class. Only problem is there is NOBODY in J.

I'm struggling with this statement here. In what ways are the maintenance on the GT3 street car less than a Cup car? They have fundamentally the same driveline except the GT3 street engine has more moving parts with the variocam components. The suspension and brakes are the same, so where are you saving on maintenance costs?

Agreed. It is a completely misguided and incorrect statement (that a race GT3 requires less maintenance than a Cup) and discussed at length in other posts.

Some argue that a race GT3 could "suffer" less wear if you don't run it with slicks (less grippy hoosiers), and at lower revs due to the longer gears; but then you are not driving it to its full potential. And even if you run it in the Stock classes you have to consider the effect of the much higher weight which IMO (and physics) is the biggest factor affecting wear and tear of tires, brakes and suspension components. Modern fast "stock" class P-Cars are very expensive to run due to the big weight.

The only (excuse?) reasonable explanation to convert a street GT3 is as a by-product on the marginal expense of the incremental steps in having gone through the process of Street - DE - dedicated track car - race car, and enjoying the process of the DIY wrenching...

Please dont take this out of context. I am referring to the purchase of an "experienced" Cup Car versus a low mileage Street GT3.

There are several cost differences when comparing the two models. One being a purpose built race car and RACED...versus a street car (low miles 9000) being converted.

1) Look at the cost of an engine rebuild for a GT3 Cup car versus a street car. My point is that many of the Cup Car fors sale will need an engine rebuild a lot sooner than a street motor. (45-75 hours on most 04,05, Cup cars on the market.)

2) Stub Axles allowing for single wheel nut (need to be replaced every so many hours) This part is not on a street car

3) Racing axles on Cup Cars (check the cost on those BLUE AXLES)

4) Some have fuel cells that will need replacing ($5000)

5) Old BBS rims will need to be rebuilt (fasteners, new outers or inner rim barrels)

1) The engines use most of the same parts with similar rev limits. If you think a street engine will last longer than a cup engine, you may want to research this more.

2) Stub axkes are cheap and last a long time

3) How is a heavier GT3/"Cup" car going to be easier on axles. If you run stock axles, you'll liquify the grease.

5) Wheels are wheels, they all need periodic maintenance

Just curious, so a street GT3 engine driven hard on the track will need a rebuild at ~100-120 hours also?

I just want to make sure I understand the discussion. I must admit I was under the impression that the street engine was more "durable" and required less "attention" as well.

Yes, and as many others you are under the wrong impression.

The 100-120 hrs is Porsche's recommendation. I'm sure many engines run and have seen more than that. If you run the GT3 engine for the same time under the same race conditions of the Cup, it will essentially have the same wear rate.
Most likely, it will still run but it will not be at 100% as new...

In my view, 100-120 hours is a LOT! In a PCA race weekend (that gives you the most tracktime among clubs) you can get max 5hrs of Race condition time (and that's assuming you run EVERY session completely + 2 sprints + 90min Enduro). So that gives you up to 24 race weekends!

... I wish my (non GT) racecar gearboxes and/or engines lasted that long...(no need to rebuild, they just kaput. buy and replace)

cgomez - thanks for enlightening me. Good info.

I have direct, personal knowledge of 3, 996 cups that exceeded 200 hours on their motors. One is still running that motor and beating the crap out of all the other West Coast cups. I ran mine for 3 years and 100 hours without any engine problems at all. It leaked 3-6% when it sold....

FWIW, I replaced my original blue axels when the car sold. They had 5 years on them without incident. The only breakage I incurred was a pressure plate/clutch, and a front lower control arm that snapped at 150 when I jumped on the brakes. A memorable code brown moment....

Guys

I think you are missing the point here.. Speed GT3 wanted a fun reliable car that didn't require the expense and work to run a Cup car..

He wants a car that he can get in and go with little to no drama.. Cup cars are great no doubt but they require work to keep them running in top top shape.. Are there cars running around with 100 hours on the engine and more sure... And a lot of these cars are rattle boxes at best.

Lets face it there are plenty of ways to skin a cat..

Speed GT3 wants a fun reliable car and that's what he is building, I don't think he is caught up in the " I have to be the fastest guy in my class" otherwise he would have gone out and purchased a car like World Challenge GT3 cup and destroyed the 99.9% of the cars running in POC or PCA on the west coast.

Okay so back to pictures please

Yes, more pictures please.

I own a 996 Cup and GT3. Like Speed GT3 I've also gone down the route of a heavily modified, track orientated GT3. The plan is race it in PCA/NASA/SCCA and have some fun. Specs for my car are still being finalised so I'm watching this post with a great deal of interest. Likely it will end up under 2500lbs with 450hp (there is a 4.0L 500hp+ option being considered as well) wider wheels and slick tires with a decent aero package.

The Cup car is raced in the GT3 Cup Challenge in New Zealand. The car is great to drive and racing in a series like the GT3 Cup Challenge is fantastic. However, I also wanted something that was a lot of fun to race in the US and hence decided to modify my GT3. The process of modifying the car in itself has been a good experience and I'm looking forward to getting it on a track soon.

I look forward to regular updates and photos Speed GT3.

This car is perfect in the following classes:
1) POC GT3
2) Nasa GT4
3) World Challenge GTS Class

Starting out with an immaculate street GT3 allows Speed GT3 to customize the car to his particular tastes. There are plenty of Cup cars out there but most of them are considerably "used". This is a great option for someone who doesn't want to go the Cup car route.

Plus for us without hordes of cash... the purchase price of a street car can be financed..... cup cars have to be purchased one way.. CASH!

I think there may be some room for this car in the new GTB2 class as they are plugging in the X51 997, with 381hp and 3050lbs, into this class and the 996 GT3 would be a perfect fit.

Speed GT......time to start lobbying!

Not going to happen. It's been lobbied for already and while the ratio works, the biggest separation (and why it's in GTA and not GTB) is the the gearbox and motor. They aren't even close.

I dont see WHY it wouldnt happen.
The numbers are the same................
Same horsepower right?

997 X51

376 hp@7200,
306 ft·lb

996/GT3

375 horsepower
284 pound-feet),

The gear box is a wash..... 22lbs of TORQUE in the X51.

This class would be PERFECT for the GT3

It's not the numbers. And you're missing the differences in the gearbox and motor (it's not hp and tq). GT3 gearbox is VERY robust and strong. The Carrera gearbox is disposable and doesn't last long. Trust me, have already gone through this process.

I thought it would be perfect as well but the sticking point with PCA was the gearbox and motor.

If you get sick of PCA rule silliness come race NASA GTS :)

Dependability should NOT dictate a car's classification!!!
That is ridiculous.

Speed and competitiveness should dictate.

While I agree with you that is not the philosophy of PCA and how the GT3 is classed. PCA has determined that the GT3 fits in stock/prepared or GTA.

At the end of the day though I learned my lesson after doing the research.....pick a class FIRST and then build (or buy) the car. Not the other way around.



It also doesn't help that there is little if anybody lobbying to add a GT3 to the GTB class. Classes don't change based on a couple guys......change comes with large numbers.

I guess the next question would be, who do you contact at PCA to discuss this new GTB Classification? The GTB2 class just came out so I would be surprised if you already approached PCA about putting the 996 GT3 in GTB2, as it does seem like a logical choice for classifying that car. And I do know of 8-10 996 GT3's that are being prepped for Club racing and with PCA not putting these cars in a compettive class, it will lose these competitors to POC, NASA, etc.

And I am sure PCA would love to encourage more racers to run with them.....the last 2 PCA races I attended were down on competitors.

It obviously has to be worked out -- I have similar issues with my GTS4 (NASA) 02 996 in PCA. The PCA rules seem too slow to respond.

Darren,

Wouldn't your car fit in GTB1 now?

Sorry, looking at the rules for 2010 GTB I still see that my GT3RS uprights are illegal. Is GTB1 something different?

GTB1 is for all 996 and 997 3.6 and Cayman S cars and GTB2 is for the 3.8 997 cars. They have listed a 997 3.8 X51 with 381 HP in GTB2 with a weight of 3050 and a weight/HP ratio of 8.01.

This would be a great place to put the 996 GT3. I am aware of the stronger gearbox in the GT3 but I can assure you that the 997 3.8 X51 motor pulls much stronger on the low end and the 2 of these cars would be a great class to build upon.

Where are these new rules? I'm just going off the 2010 rules posted on pca.org

LOL, this is f'k funny.
speedgt3 and dell are really on same side. we all want to get GT3 into hp/wt class, you can call it gtb gta gt****. i dont care about name. but PCA is old dinosaur and dont move fast. have you tried ever to argue with DMV.... the big rock in my backyard responds faster and has more logic than either pca or dmv.

while like many smart ppl, dell learned to pick a class first... i tried that. but what i decide to do is drive what i want to drive. and have fun. winning is over rated, unless there's BIG purse money. since i make more $ working than racing....

i find it kind of strange that it's my money but some organization would decide and tell me what tires i need to run, how i can and cannot modify my car....

dont you all find this strange? you goto macy's to buy a blue blazer, but the sale staff tells you "no", it's monday, you must by a red blazer with purple slacks...

speedgt3, go for it. i may do something insane like you too. and i may just drive my daughter to school in a race car like yours :-)

yes, most of my friends all think i am 99.9% psycho.

Pick a class first with PCA, in what I've seen, is stupid. There is always A CAR that dominates in every class. This is why I don't race PCA but it's also what I want to see change so that I can.

What is more simple that NASA GTS hp/weight ratios?

My assumption being that if A CAR is fast now, a reclassing may make it not so by the next year.

==> correct, even the pro series do that.and unless you get new car every year, it's like chasing your own tail.

Ok so why not use HP/Weight as THE rule? We're not pros racing NASA/PCA/whatever, we're guys having fun with our money and our egos. At the end lets go have a steak dinner and make a great time of it.

racing is no different than politics. and i hate politics.

yes, there's always a dominating car. and what if you dont like the dominating car's look, sound, blah blah....

dude, you are like me.
but i am too lazy to chat with pca.
if you beat them into submission, i be very happy.
i think dell gave up already ;-)

I did give up on PCA. I didn't race the GT3 b/c they wouldn't class it in GTB which is where I thought it should as does several others and I was NOT racing it in GTA. The problem is they want overwhelming support which isn't going to happen since there are not that many GT3's running.

Biggest regret I ever had was sell the GT3 to follow the "pick a class first, then get the car" theory. I did pick a class and then found the car only to learn that even in "stock" class there is some serious rule breaking there and I wasn't going to do it.

Hence, the reason I built the spec boxster. About as close as you can get to a true drivers class. Not much variance at all in hp/tq and it comes down to driver talent and setup. The way it should be.

If GT3 was allowed into GTB, and the classes were large (which they are pathetic anyway) then I'd pick a GT3 over any other car in GTB.

Yeah, if you want to race PCA and you don't want to deal with this rules bull****, then Spec Boxster makes total sense.

Just picking this thread up....

1) For all the "let's do it all weight to hp" guys - Take two identical cars and put bigger tires on one...are they the same? Take two identical cars and take 200lbs out of one but add 30hp to another...are they the same? Take two identical weight to hp cars and give one a sequential box....are they the same? Take two identical cars and give each of them different gearing and brakes....are they the same?

The answer to all of these is of course not. That's the problem with weight to hp....and I generally like weight to hp classes. However, don't kid yourself that it's the fairest way to class cars.

2) To the original poster who is converting his GT3 to a race car. As I see it, you could have taken half your cost of the conversion and had a racing budget for a few races. That said, I understand your desire to do it and have what you want. I did it myself which is why I now counsel anyone who is thinking about this to NEVER do it. In the end, I had a GT4 car and, on an hourly basis, it wasn't tremendously cheaper than my 996 Cup. The main problem with building cars is that you are piecing things together that don't have the engineering behind them saying they will work together so you end up constantly chasing the weak link. It's frustrating and costly.... You see the results of this on any given racing weekend with all sorts of mechanical issues in the classes that tend to have these cars. Outside of my own driver error, my Cup has never EVER failed me mechanically.

3) I've been racing for 4 years and have raced with NASA, SCCA, PBOC, Grand-AM, FARA and PCA. They all have their strong and weak points, however, I think this statement is true: IF YOU RACE A PORSCHE, PCA is the best racing venue for you. It generally has the most robust fields and the classes keep things competitive. Is anything perfect...NO. We're not talking about perfect, we're talking about racing. Again, IF YOU RACE A PORSCHE, PCA is the best...IMO.

4) The whole reason I bought my 996 Cup was because it's a spec class. GENERALLY, you don't have to worry about being out-motored, out-suspensioned, etc. The racing fields are deep (26 996 Cups at Sebring, 23 996 Cups at the Glen) and the top 5-6 guys are pretty quick. I know Cups are expensive (although getting cheaper every day...) but the original poster, by the time he's done, won't have any less money into his car than I do mine and mine will hold more re-sale value (I hope).

Nicely said Peter. Agree 100%.

FAP

oh hey nice cage! I'm getting the same people to build mine. Oh and it's good to see your going to be safe having FUN. Enjoy it in good health!

just curious...... but where would my 997RS with full cage class in PCA?

Another route would have been to find a 996 CUP tub or roller and take a street GT3 wreck or donor to complete the CUP build.

To take a street 996 GT3 and install cage other than bolt-in examples such as Clubsport, Custom cages or Autopower can be expensive and time consuming.

I have seen quite a few of GT3 Street cars get full cage and cup treatments only to hit used market with poor resales.

I have much respect to those who do it however because it is totally custom, costly and passionate.

I decided to avoid this route and stick with either bolt in cage (which i did) or CUP tub/roller project.

Guys,

Please remember, GT3 Speed is building this car to mainly run in POC and World Challenge GTS! It's not all about PCA. POC has some great racing and now they have the power to weight spec classification and this car will fit nicely in GT3, where it won't have to run against factory Cup cars. PCA is missing the boat not classifying the 996 GT3 street car in GTB 1/2 as there are many of these cars out there being built for wheel to wheel competition.
For WC GTS, this car will be a strong player in that class as the factory 996 Cup car would have to compete in GT and that car would NOT be competitive.

This cage is built to factory Cup car specs but with the added benefit of Nascar door bars, which frankly, I wish came in the factory Cup cars. And if you are going wheel to wheel racing and you are running with a bolt-in cage, I question the logic in that decision....


Lastly, I will make this point again.........not everyone can write a check for $75K - $200K for a Cup car as you can't finance them like a street car. Converting a street car makes a lot of sense for most of the people out there.

Taken 50% of my costs and had a racing budget? Not sure what this means?

I have top notch engineers, fabricators, and the best PORSCHE tuning shop putting this car together. All the suspension pieces are either PORSCHE Factory Parts, or proven race parts designed and tested by GMG, so what do you mean "no engineering" behind them? Do you think the Porsche World Challenge Cars, or Grand Am cars are raced "as delivered" from the Porsche Factory? I can tell you first hand they are not even close. From suspension modifications, to launch control, to ABS to brake calipers...etc.

Not a lot of experience to "counsel" potential car builders. :eek:

[/quote]

If my car is 1 to 1.5 seconds a lap faster than your car, with the same driver, which car has more value?

Agreed. And they have a LOT more budget than 90% of us on here to make sure all of it works together.


How much is a "lot?" I've built a car from scratch and purchased 2 others and spent the last few years and a lot of money/time racing them. Let me know what the experience threshold is (5 years, 10 years, etc) and I'll keep that in mind when I post in the future.


Absolutely nothing to do with what my response was about. There are a lot of cars faster than my 996 Cup out there. Does that make them all more valuable?

Don't get me wrong, I've done the same thing you're doing. I hope it works out really well. I would never wish anyone anything other than the best with their project. However, having done what you're doing, I'd never do it again...

Interesting discussion..... No doubt that the cost per hour of operation of the GT3 "street" car is similar to the Cup. This particular car was pristine and very low mileage, (though I suspect many more track miles than the owner may think). He bought the car extremely well and sold off a lot of parts that came with it. While the car won't be cheap, it should be really fun and still less expensive than a pristine Cup with similar hours of use.

WOW! Done correctly! Very smart decision and upkeep is so much less than a Cup.

Craig,
Why do you feel upkeep is less on a 6GT3 street vs. 6GT3 Cup? Obviously, most cups run slicks and more "street" cars run R-compounds, but that's not an upkeep issue.

Same rotors
Same pads
Same motor (plus vario)
same trans (but brass synchros and weaker diff)
more weight

Given similar use and tires, I would estimate that upkeep between the cars is virtually identical.

here we go again...

I just want to see the car. So Laguna w/POC for it's debut?.....

jrgordon, will there be noise restriction at Laguna?

Rotors and pads same cost, but oh boy the rest (can be/is) a whole different deal.

Yes unfortunately. 92 db IIRC. We get lots of weird muffler arrangements some of which are very creative.....

92db is correct.
you either run stock 996gt3 exhaust or make a big saxophone like muffler.

The car is finally in the FINAL stages...............

Seat finally mounted.

what kind of lwt doors?
how much are lexan? who made the lexan?

Porsche Motorsports for the LEXAN

Love this car.. One of my favorite builds at the shop right now..\

Cant wait to see out at the track.

nice,
what kind of composite doors are those?
getty, mashaw or pmna?

What is the final weight?

Top secret. :nono:

We are not done yet with the weight removal.
We are currently under 2775 which was our first goal.
We are hoping to get another 75-100 out. :bowdown:

A HUGE thanks to the guys over at www.gmgracing.com

They are amazing.
They turned a street 996 GT3 into a CUP CAR.

Let them build one for you, from your street car.

My car weighs 2650 lbs and has 514HP. Lighter weight to your point is a BLAST :cheers:

Thats a helluva good ratio!!!!!

:to_order:

Ya, but the response is NOTHING like a GT3!

Crass question to Speed GT3: What did the makeover cost?

Inquiring minds (or at least mine) want to know?

Great to see it out on the track for its maiden voyage!!!
Drivers got skills!!
Drove the entive 50 min GT Race in rain ON SLICKS!!

The car did a 1:33 this past weekend at the Global Tuner GP, which is FAST for Laguna for a 911 GT3 Cup (and this was a GT3 built into a cup car)
We are still 100 lbs overweight, and we dont have cup gears.....................YET.

:corn:

Thanks AZ..........it was crazy out there on slicks.

what is the total wt of car, no fuel no driver?
what doors are on the car?

2775 with a 100lbs or so still left to take out. (ac, condensor, exhaust pieces etc)

We are shooting for 2650 lbs.

Fiberglass doors
Carbon decklid

2650 is f-ing light for a GT3.. that thing will be a rocket!

Good to see you at Laguna....

I must say that 996 GT3 was so much fun to drive and very easy to point and shoot. In fact, it was easier to drive than my WC 997 Cup.
I only took it out for 6-8 laps but it was only 1 second behind the fastest 996 Cup times that weekend.....my hats off to Todd and Aki who set that car up at GMG!:rockon:

Was anything done to address the issue with glued in water fittings?

Glued fittings?
Not sure what you are talking about.
Can you elaborate?

he's talking about coolant hoses.

I've heard those things occasionally come loose from the motor, what's the fix?....

I had mine TIG welded in place. There are other opinions but I'm a welding fan. Now I'll never worry about it again.

use water not coolant and pray a lot.
i flew off T9 at TH two years ago when one hose gave up ghost.

Brad did you guys change motor mounts in your car and if so what did you go with? I've blown a couple of stock 996 mounts and thinking of switching to cup car mounts or Wevo's.....

The best $500. you ever spent..


NICE CAR.... Let us know how the campaign goes...

Have not changed them. Not sure if they are beefier over regular 996.
No problems so far.

Are you going to the POC event at Willow in Dec?

I put solid TRG mounts in my car, which are spec illegal as far as I read. Seems stupid, like many PCA rules.

I replaced mine because the stock mounts ripped out and because it was impossible to make a 2-3 shift with the car loaded.

thread them in bolt them down or weld them, or if you are like Mooty put water and pray. : )


How about the 993 semi solid I use.
Very light and robust.
Would those be illegal to PCA rules?

Semi-solid should be fine -- as long as there is some sort of bushing in there it's fine by my reading.

Any issues with your knock sensors?

Most likely....

Nope! Why do you ask? Vibrations I assume?

I understand limiting suspension bushings in the rules but limiting motor mounts is just silliness. Is that so we can drive our caged race cars on the street?

PCA rules stewards are more out of touch than GW Bush, who recently was quoted saying the thing that most upset him about his presidency was Kanye West.

I was seriously considering this avenue, and actually starting recruiting some folks at the POC to do this very conversion from Street 996 GT3 to Track 996 GT3 and have 8-10 guys come along and form our own 996 GT3 'Spec' class. Run on DOT's - no slicks. Played with this idea for a while, and then looked into the quickly dropping prices on 996 Cups. Didn't take me long to figure getting behind the wheel of a late year 996 Cup was MUCH more friendly on wallet and mind, and mine is getting delivered TOMORROW!
My reasoning in the end to step away from the conversion project was 1) money and 2) time, and 3) you got the conversion route, you're potentially going to end up wanting a Cup anyway (I did), and so if the true object of desire became within striking distance (they're now going for anywhere near $40k to $60k for decent 996 Cups - believe me, I've shopped hard over the last month, and that IS the going price range.

btw - I've posted a WTB ad for an enclosed 20'-22' trailer with some cabinets in it - if you know anyone, please let me know! THANKS!

$40K-$60K for a 996 Cup??? Haven't seen anything worth considering for less than $70K that wouldn't be a maintenance nightmare or a car on it's last legs.....

r u the white 6gt3 or yellow 7gt3 at LS this year with POC? i am the silver orange stripped GT3, see avatar.

pm me.

what cup you get?

oh, forget 20' trailer. you will regret it.i bought one BRAND NEW 20k, sold it 10k in 4 months. now 24'

Yellow GT3. Bought white 05' from TRG....

^ u know too much ;-)
when are you buying another cup.

Don't know about the West coast but a nice 6Cup can be had for less than $70K over this way.

Guido...son of a B! I'm not ready to go cup yet, damn! Ok lost my competition now for POC TT in NP, just when I thought we were maybe thing of spec'g GT3, now I gotta start thinking 996 cup for 2011. Well you got a few more years on the track than I, so I'll probably run the 997S for another season...or two. Famous last words. Congrats on the car! Just looked at it on the TRG site, looks nice!! See you at Willow this weekend.

On the cars first outing, it turned

1:33's at Laguna on old tires

and

1:25's at Willow Springs on the same old tires.


Very well set up by the Porsche experts over at GMG

So is this one for sale in NY for $50K in your "maintenance nightmare or a car on it's last legs" category?
http://forums.pelicanparts.com/porsc...-gt3r-cup.html

Just wondering....

Any more events on the car? How is it doing?

Tom.....so where was that car for the 6 years before it "resurfaced"?

Tom,

Here are my observations.

Looks like a nice car .......

What class will that car run in and be competitive.Looks like there are limited places to run the car and WIN.

PCA...killed in GTA.

NASA GTS-5 - would get killed against the ex GMG WC Cup car.


Is the motor rebuilt by PMNA?
Also the car has a fuel cell, when was that replaced? $$$$$$$
Radiators replaced?
Factory carbon parts with Porsche Part #'s or aftermarket? (keeping it Factory Pedigree)
Factory tansmission parts?
No AIM/Motec data acquisition?

Most of the cars on the market today have some sort of Data Acq. Whether its Motec or AIM. Also, most if not ALL of them have PMNA built engines.
This will certainly affect AND impact market value, longevity, and PEDIGREE.

Probably sitting in someone's garage in pieces. I think there's a few cars like this one just sitting around, the red-haired step children of GTC3 cups. At least with POC now running weight/WHP classes that car would have somewhere to run though I doubt in would be competitive in our GT2. NASA raised thier GTS5 mulitplier from 6.5 to 7.2 this year so I doubt it could make it into GTS5, most likely GTSU where like GTA it would get slaughtered. Too bad, it looks like a nice build and I bet it's a fun to drive....

Hmm, wondered what it dyno'd at....

Same project for me!!!!!

^don't bother! for $68k you can now buy this car. For the price of a good street car. Interesting results.

i thought he just built this car?

https://rennlist.com/forums/porsche-...-for-sale.html

...appears so...

So I am guessing he bought a cup car? It's a beautiful car, well done and someone can buy it with borrowed $ since its street titled.

Just curious - why would this car be slower than a "factory" cup? Is it just a matter of getting rid of remaining excess weight, or is it something else? (grip, power, etc) Lovely car - hope it finds a good home.

it is a killer car. fresh build too!

with full cage and title it could run the Targa Newfoundland 2011 with ease :)

I hazard to guess, there are so many circumstances that lead to selling that are unrelated to the car, the only one which would be germaine here would be if this path was better suited by a cup. It's a very nice car/build with what you can see and had to be invested. Someone will get a steal, available cups seem to be drying up, but there are a few of these "baby cups" out there.

Agreed, this last year was a bit of a "Golden Window" on good Cup availability and price...

Power is equal and can easily be agumented. Gearing is wider and taller, but mostly it's weight. You can get "strippers" down to cup weight or much less, it just takes money....

The car turned VERY competitive times on its MAIDEN voyage (first event after its completion) relative to 996 Cup Cars that were at the event. The car did a 1:33.6 compared to a Cup Cars range of 1:32.3- 1:33.4
