Hell, the 944 looks like the V-8 belongs in there! Thinking about it, an aluminum block sbc would probably weigh about the same as the stock 4 banger...maybe less?

(Bill... Would your trade your 928 for one of these?)

Supposedly the aluminum SBC is only about 100 or so pounds heavier than the 944 engine so most of the weight balance is preserved.

You do lose your power brakes (and a/c) though. Which is a little frightening.

There are at least 2 SBC 914 conversions here in Houston. My 914/6 was 200 hp. The "mild" conversion was 300hp. The scary one was 450 hp. I think that one was an LS1.

I read about that motor in the last (not newest) Excellence. Impressive!!!
Didn't understand the part about eliminating the serpentine accessory belt though...those Germans!

I can understand why one would want more power.
But why oh why would one go for more power and at the same time be content with lesser brakes than he already had????

You don't necessarily loose power brakes, you just can't use the factory master cylinder. This car has a hydro boost master cylinder which is power assisted.

It is the gold canister on the right rear near the firewall.

Many others feel the same way but if you don't want to do it, don't do it.
It's a little egoistical of anyone to suggest that it is wrong or that no one else should do it either.

BTW, the flat six is heavy. Not light.
An iron block chebby V8 with headers, alumimium intake and heads weighs close to the same as a fully dressed 3 liter Porsche six and puts out twice the power and that horsepower is cheap.

There are some people out there that think that anyone who spends $7k or more to rebuild an engine that makes 200 hp is wrong.
That same amount of money would build a NEW reliable 450 to 500 hp from a V8.

I was watching a grand am race the other day, there were three Porsche powered cars entered in the daytona prototype class.
One had a flat six and the other two had V8s. The V8 cars were faster.

When the 3fe kicks the bucket, anything other than a SBC for me. I'm talking anything, a 134 hurricane would be better.
There is a reason the small block chebby is so popular. It's because it works really well, is extremely reliable, is inexpensive, easy to get, and there are a gazillion aftermarket parts available. In other words, it's a smarter move than other V8s.

Buy hey, if different and dumb is someone's thing .... j/k

I can see a lot of 928 with small blocks in the future.
Have you seen what it costs to rebuild a 928 motor?

For the 911 it has to be air cooled for me. Just wouldn't "feel" right any other way.
That flat six has plenty of character and feel.

I can see the logic for using a V8 but owning a 911 isn't about logic.

What about an early 996? That may be worth doing considering how cheap you can pick one up with a broken motor.

I'd prefer that engine in a mid 80's 911 Turbo (my fave of the 911's), but yeah...i'd take it, even in that ugly lime green VW Beetle derivative.

Not only that, but a Porsche 928 V-8 motor weighs in at SEVEN HUNDRED AND FIFTY POUNDS!!!

Switching to an LS1 can save over 300lbs of curb weight! That's like adding 50 horsepower just in weight savings alone.

928 motors last a loooooooong time though, because they are so massively over-engineered.

One of the 914 guys put a 928 motor in. I think this was done to keep the car "legal" for autocrossing. The thing looked like an alien spider had attacked the back of a 914.

I have a wonderful newly rebuilt 2.6 race motor in my 914.
200ish HP.

When it blows, I likely do a SBC conversion.
It would cost $10k ( maybe more ) to duplicate my current motor ( intake to exhaust, including the build )

I know where an old 912 has been sitting for at least 5 years.
Perfect candidate.

I know this discussion has been done before and to each their own. I need to clarify my thoughts - I was thinking more along the lines of the 911 turbos. I understand a 914 (be kinda cool), 924 and even 928 (porsche maintenance nightmare). But I just don't get an american V8 in a 911 turbo. For those that have done it - congrats. Many tech and logistics problems to overcome - some installs do look very good.

My personal preference, at least in a 911 turbo, is a Porsche motor with a boat load of mods. I like the Porsche "hot rod" concept. Yeah its stock - but........

Just MHO

I do not understand why people think 928's are even one tiny little bit harder to maintain or repair than any other Porsche.

All you need is a set of common hand tools, a few specialty tools, a jack, and a couple jack stands, and anyone with mechanical knowledge can easily fix any system on the car.

It is a very straight forward and simple design.

a good friend of mine is doing a renegade conversion. he had a custom SBC built. LS(something). i think the target HP is in the neighborhood of 600hp. motor is in, fuel rail is done. something happened to the motor/tranny mate..no details.

he had FIKSE shipped. i think the rears are 13". custom body work to fit the rubber. apparently, it is very close to being finishes. the guy spared no expense. full cage, etc.

i'll try to get a photo. the car is in oakland.

the same guy bought a dodge charger and sent it off brand new for some UBER HP motor. same custom body work. it will be sick.

1. cheap horsepower
2. gets attention
3. shock value
4. Building one is something interesting to do between beers
