928 owner pet peeve
#31
I love the 928 motor. I had a 99 6 spd fixed roof c5- I liked that motor too. Maybe there needs to be a shootout to see once and for all which setup is best....I have no opinion really, just lust for the ls7- it's really rev happy!

I agree 100%. A transplant needs to make sense - not just raw Hp
The Porsche engine will last for ever if cared for. The sound and power delivery is where it should be for this car.
$4500 buys a good engine if you've blown yours, $3-5000 buys some form of forced induction. If you sell the car - take it off for the next car or sell it.
Pic below is a transplant that makes sense - Toyota 1.8 liter + 5 spd into a MG Midget - car is always worth very little, the 1600 cc motor is 60 hp and fragile. The Toyota 1.8l is 100lbs lighter, infinately more durable and with the 4-2-1 custom stainless exhaust, and 4 carbs from a Yamaha motorcycle...... 100+ Hp.
Cost of motor, 5 spd and carbs.... $200
Got $500 for the old MG motor and tranny!

On Saturday I got to stand around and laugh at 4 C5Z06 owners try to figure out how to fix one of their Vettes after a race. The cam position sensor was failing and the had a spare in the giant Kenworth+stacker rig sitting a few feet away. The problem was that none of them knew how to get to the sensor without removing the whole front of the engine. I asked the owner (former 944 owner) if he was ready to go back to a Porsche for ease of maintenance. He looked at the ground and mumbled that he's getting close. Yeah, he has 385rwhp (when he's not having engine troubles almost every weekend), but his car weighs over 3400lbs stripped down to race weight as an ST2 car. My 928 will weigh about 3000lb... Maybe an LSx would be great in a 928, but maybe you're just looking for a bigger headache.
I'm not suprised his car isn't running like a top, he doesn't even know how or where to locate the problems it's having.

I believe that certain cars should be left alone. If someone did a swap on Kermit, I would would be the first to organize a lynch mob.
Although I would never do the swap on my car, I do believe that I have the right to. I love my car. It is an 82 with unknown miles. If it fell off the face of the earth I would be the only person that knew it. Who would care if I did a swap on my car? I have already done enough to it that is not original. It is a stock engine, but it is no time capsule.
I definitely see where the complaint is coming from, but I think once you buy the car it is yours to do with what you please. I feel very liberated that my car will never be worth alot. If it was, I would be afraid to do anything to it. As it is, I do whatever I want (can afford) to it.

I'll play devil's advocate here.
C5Zs are mid-to low 12 second cars. If you run a 13 with one, your either just bought it, or you can't drive it. There have been a few in the 11's too, with STOCK tires. Not many, but the CAR is capable. Tires is a different story, but more 11 second timeslips with tires, like you said.
Drivers make all the difference. The car is capable, period. A 928 with NO boost will not break into the 12's most likely, and most certainly won't get NEAR the 11 second zone. With a tire and boost, maybe, but I have yet to see an 11 second pass on this forum. Maybe i've missed it, I don't lurk here as much as I used to.
Oh, and when a 928 motor is making in excess of 1000hp to the GROUND, maybe, just maybe, it'll be in the same league as an LSx platform.

Stock means, no modification, and the tires that came with the car originally? How does that differ?
But, just to prove YOUR point. Car and driver posted quarter times of 12.7 for a 385HP Z06. Then a 12.4 for the 405HP version. Most cars are of the 405 variant.

This is an interesting topic for me, because it's something I thought about.
I say thought about because I have a running 928 motor, and nowhere near the amount of money it would take to do this, nor the inclination right now, but there are several points for it.
First and foremost however, I'll say that cars are a hobby. Everyone is different, likes different things, different tastes, and different goals. If we all liked the same thing, then it'd just be boring. How unique all of our cars is, is one of the things I find more interesting about this collection of enthusiasts.
That having been said, the LSx is an amazing motor. The power delivery even in stock, LS1 form is simply fantastic, the HP and torque curves are smooth, and the motor revs well for an OHV v8. All in all, it's pretty kick ***.
928 engines are quite the variety. I happen to have a L-Jetronic 4.5l, so I'm pretty low on the performance scale. Outside of some ridiculously expensive exhaust modifications, or some ridiculously expensive top-end Euro 4.7 swaps, or a ridiculously expensive supercharger kit, there's not a whole lot of ways for me to get more power out of it. For that very reason, I'm not worried about power. I just want my 928 to look good, and work well. There's plenty of electrical bugs and the interior needs a lot of love, so power takes a back seat...
For now. What about in the future? If I have this car for 10 years, parts will just get harder to find (sadly) and if the motor gives out, it might be cheaper to put a LSx in there, regardless of the weight savings and performance gains. I'd rather my car be a LSx swap hot rod done right than a parts car.
Of course I'd rather have a stroked 5.0block with euro 4.7 heads, cams and intake, but I would also love the $6,000 it would take me to make that happen. Until I have that money, I get to keep tinkering on it.

Stroking aside- I could give you the 5.0 block with 4.7 euro setup for much less than $6k

...yeah right

I would certainly not consider changing out the engine in any 928 that was running well for anything else, but... people are different. I replaced and painted the wings, took off the rear wiper, and headlight washers and like it that way. If someone wants to put a "alien" engine in theirs, and all they are interested in is the cosmetic quality of the 928, then that just means there will be more original engines out there is I ever need one.
I'm glad everyone doesn't like what I like, that makes mine more special. The important thing is that we all enjoy our "hobbies" and have long and happy lives.
To each his own.

If you're looking for a fun car to drive and not a Porsche nut like us, it makes a lot of sense. There are far more aftermarket parts to customize your engine, parts that will be available for years. Who can say in 5 years if any of the big 928 vendors will be around. 928 motors will become harder to find, making a $1200 Junk Yard LSX more attractive.
Anyone who has rebuilt thier shark heart can attest the parts are crazy expensive compared to a SBC. From rings sets, to bearings to gaskets, it's all much more expensive. That LSX can be very cheap to maintain or modify in the future. Going boost can cost half as much with much more HP on tap. The current limits for a shark engine on boost are known. With out serious money for custom crank, pistons and rods, you can't touch a boosted LSX.
Is it still a Porsche? I suppose not, more of a hybrid. But fun? Oh yeah! Not my cup of tea, but I fully understand it. If I catch a seagull, I'm having BBQ! Not because seagull is worth eating, but so if the conversation ever comes up...I can say been there, done that. Little I do with my shark makes sense, I just like to tinker and the journey is fun.
I have a mercedes CIS distributor, does that make my shark a Non-Porsche now? If there was a direct off brand 5 speed swap, most of us would be switching to be able to put more power to third gear and to fix syncro issues. I don't think that swap would get as much crap.

Let me say this, I said before this tweaks me the wrong way but I would be near as proud to have a c5 or c6 Zo6 sitting next to my shark as they are fantastic cars with incredible potential. Ricer said that the limits of the 928 engine are known. I disagree completely. Erik( Hacker) is running 17-18 psi and is getting incredible power from his 16V. Another reclusive Wisconsin fellow is in the 20's. The flexibility of the 928 engine has not often been paralleled. I myself am running 13psi on a completely stock engine with a 6:1 fmu and HUGE injectors. The fuel looks great with no tip in and 11.7 steady at full tilt. My G-tech tells me I can run 3.7 0-60 and low 11's in the 1/4. Idles perfect and revs like a sportbike.
