Yep, my guess is all the AWD and front engine RWD/AWD cars will have one. My E55 actually has two guibos on the drive shaft. Need to swap them out on that project car.

Bronz, glad to see your 997.2 is back in shape.

Think about it a bit before you decide to sell. I remember you bought it for a steal out of Texas, I think it was the cheapest 997.2 C4S in the country at the time. You paid up for the issues with the car, but now you know it inside and out. Yes, it's expensive, but it's just money and you can't take it with you in the end. I almost sold my 997TT even though it's a bit of a basket case, but there's really nothing out there that can match the experience that this model provides. Good luck with whatever you decide to do. Thanks for taking the time to document your build.

You don't have to buy a new Porsche to be in their data base or have a chance at some goodwill. I never bought a new Porsche but I've had three 997's serviced and repaired by the Porsche dealership in my hometown. I'm in the PCNA data base, I receive all kinds of PR material from them on a regular basis and I have received some goodwill from the dealer over the years.

I have a lot going on ahead of me and i will apply the knowledge i gain here in the future. Most of you probably dont know my age, but i might be one of the youngest members on this board....
I suspect that those who recommend an indy for repairs instead of a dealer are those who have no warranty since the indy will typically be substantially cheaper. If you have warranty, what would be the reason to take the car to an indy? The out of pocket expense will be the deductible which will be the same no matter which one you choose.

Guibos or flex couplers are used on applications where the driveline angles are the same( straight shot from output shaft to input shaft) A universal joint or constant velocity joint requires some misalignment to keep the joint lubricated. Guibos are typically used on independent suspension cars where the driveline angles stay constant( solid axles like trucks and such the axle moves on the spring) A universal joint or cv joint is commonly used in conjunction with 2 guibos to compensate for different angles between input and output shafts.

If your AWD 911 is experiencing guibo failure, you may want to investigate the front and rear motor mounts. When they wear, especially the rear dropping, they cause a misalignment of the transmission to the driveshaft that the guibo must compensate for every rotation. This constantly flexes the rubber disc and prematurely wears it out.

I think that a personalized plate is needed should Bronz decide to keep the car.... it's just too special a car... how many 4.0L 997.2's are out there aside from the GT3 RS 4.0?

Yup and its actually the same part #!

In my industries standard policy due to the unit being out of warranty would be to supply the transmission at N/C or near cost and cust pays the install or 50/50 with the customer for the part and installation.

On a side note Only 24k for a Raby 4.0 count me in ...may just want one on the side in case mine ever pops !!
Yeah maybe if i would have pushed further and tried to contact more people at PCNA maybe something could have been done.

Most likely it will be another Porsche for me, but Keep us posted on your next moves!
I feel ya! Ive been a big Porsche fan since i can remember, and i still do love their cars and design. Its just the string of unfortunate events that has me turned off for now. If i sell it, ill be back eventually

Thats the way id like to look at it as well! As long as im healthy and alive, a failed engine or transmission is not going to make my life miserable.

LN Engineering in Momence, IL. They mostly do machining work and manufacturing of IMS Solution, but they do have a small shop that they work on cars and theyre really good at it. Great guys.

I could be pretty happy with that just right G50 Carrera coupe in Guards red. It's simple. It's a lot of fun (not as quick) and my best bud life long pal rebuilds these for collectors. White room tech back when Porsche dealers had such things for engine and transmission internal rebuilds. I was only 21 when got my first P car. New 914 first year out. That makes me 71. That car and pretty much ever series over the years has had a flaw or two that were pretty pricey for the time. At least consistent.
Sort of like cancer research but there is a really good PDK stickie at the top of the page. Sometime in here there will be a PDK rebuild guru guy like Barry Hart, Jake and Navarro. Just not yet.
Glad to see you around Porsches for so long. I really love these cars and maybe potentially downgrading to something more simple and less expensive might be a good option for me as well. Having thoughts of going through something like this is whats scaring me away for now. I did hear that some company outside of US was able to crack the code to these PDKs finally, so theres definitely someone looking into it. Hopefully in the short future, we will have these rebuilt at significantly lower cost.

You got me beat in your knowledge though! I do like to wrench as well, but the things youre doing to your Turbo are impressive!

I think it might be too late for that on this car, but ill definitely keep this in mind on the next pcar!

Not really a failure but after 80k miles it was starting to show some hairline cracks. I think thats pretty normal for that mileage and the kind of stress it goes through.

Thats impressive! I bought mine when i was 26 but have been drooling after them since i was a little kid.

Always wanted one, but never came up with a good one. Any suggestions are welcome

Also, i got a quote from Fidelity they could get me a powertran warranty for 4yrs/48k miles for $4067.

Technically this warranty would only be good for the PDK and differentials. Im pretty sure Jakes engine wont need the warranty plus it already has a warranty and i dont think they would cover the engine that has been bored and modified.

Having 4 worry free years for $4k might not be the worst idea. What do you guys think? I should have looked into these warranties when i bought my car, but never did since i thought these were supposed to be bulletproof lol.

That is not a hateful price, especially since it should cover the engine as well. How is it not a Porsche spec, street driven 9A1 engine? Not that you would need it, but if you sell early it would be a plus for the next owner. What is Jake's warranty on yours?

$83 buck a month for 4 years. Not bad insurance, although its 50/50. It's a much greater car now, but other drive line items can go wrong, especially with the added power. But, and there's always a big butt, the rest of the car has the same stuff as the turbo's....so, I'm probably more torn the more I think about it......GL with decision, but u have one of thee most bada$$ 997's on the planet.!

Never lost money on an extended warranty. Bought a 3 year Fidelity Platinum policy for my GTS not long ago. Mostly because of the PDK failure on my -09 C4S. Not cheap. In retrospect I think I would have been content with the powertrain policy you bought. I paid around $5,500 for the Platinum plan which is basically the same as the factory CPO.

Bronz,

Glad it worked out and fantastic looking car! Where did you get the 4.0 emblem on the deck lid?

Sometime lighting will strike the same place twice... or more.

Thanx for your posts.... sad to see you go.... but very understandable.

EXTREMELY well put Bruce. I would only add these cars are everything those genius marketing folks speak of....when they work.

How would they even know if the engine was modified if you didn't tell Fidelity?

This is the thing with warrantees...at least for me. I never ever buy them except on my Porsches. Granted I grind the sh*t out of the price on them, but I look at it this way. I can drive the snot out of the car and not worry "oohh I shouldn't have gone this far or fast" Just drive it like there is no tomorrow. I know that statistically, I should not and that Fidelity makes money. I know that I have the cash to cover any repair. But I also know that without a warranty I have a little voice in the back of my head that worries and I don't want to hear it.
