There was just nothing to be said for the early 928 engines, other than being prettier to look at than a small-block, and I can’t imagine there’s that much to be said for the later S4 engines either. My '83 was era-weak, about 220 hp or something, and I don’t think they ever got much past 300 or 350 hp. Being 200 lb heavier while being no better performing and far more costly has to go down, to me anyway, as an engineering fail.

It was the '80’s, engineers didn’t fail, the government made it impossible for them to make efficient engines because they had to figure out how to make power, while piping the exhaust into the intake. 220 HP in '83 was impressive, considering the '84 Vette came out with a whopping 205 HP. Hell even the Ferrari 308’s of time were only producing 230 HP.[/quote]
From 3 liters I think, not 5.0

Well, 4.6 L’s but yeah, the Ferrari engine was clearly better.[/quote]
But that would have made it a 468 before its time, not a 308

My bad, I meant the 928’s engine was a 4.6 in 83-84.

It’s definitely weak by today’s standards though.[/quote]
So it would really have to go. Even if the trouble were taken to get it to perform, which I’m sure could be done, it would still be 200 lb heavy, for (so far as I can tell, but I could be wrong) no real value from that added weight.[/quote]
It achieved a 50/ 50 weight distribution. Dropping 200 lbs from the front would change the car’s dynamic quite a bit. I guess my big problem is it really wouldn’t be a Porsche anymore. I think some old fashion porting and polishing, removing all the pollution control could easily get 300 hp or more from that motor and still keep it a number’s matching car. Hell, you could do it in a way that nobody without a wrench could tell anything is different.
I am kind of into making cars a better version of themselves. It depends on what you have to work with. If you just got a shell, you can go nuts.[/quote]
Ideally I’d find a car that was in great shape but had engine issues, or alternately, would have it lined up where someone else really needed the engine and would benefit from it.
I just view the 928 engine as being where the car fundamentally has a very “blah” aspect to it. Otherwise, regardless of vintage the car seems to me still excellent. There is little to no collector value to 928’s in any case. An excellent example can be had for $7K.
A large number of 928 owners have done the conversion: it’s well-traveled territory. On the weight balance, if desired I suppose it could nearly be restored simply by moving the 42 lb battery from the rear to the front (though I’d go for a lighter battery as well.)[/quote]
That’s the good thing about the 928’s nobody wants them. I suppose it may be the low power to displacement ratio. They were fast for the early '80’s. The 911’s were far better engineered. It’s hard to believe they wanted to replace it with the 928.
I’d imagine you’d have to replace the entire drive train, right? I don’t suppose the tranny hooks right up to a Chevy small block?
Or you could go a different route an get an old Miata with a Ford 5.0. Apparently, the motor mounts were in the exact same place for both engines so they pretty much bolted right in. There was a shop in California that used to do the conversions. That would be a fun sleeper car. Except the exhaust burble might give something away.
