Porsche 911 Gets LS1 V8 Transplant

Detroit muscle meets German engineering



V8 engine. Porsche 911. It's fair to say that these two phrases are not easy bedfellows; the Porsche 911 is as synonymous with six cylinders - preferably of the horizontally opposed variety - as the British are with Queuing. We just wouldn't have it any other way.

But there are always those who like to mess with the status quo. One such fellow is '1dirtyZ' of LS1tech forums, who is in the process of slotting an LS1 corvette V8 into a Porsche 996 Turbo.

But before the Porsche purists cry foul and walk away from their computers in disgust, 1dirtyZ (shall we call him Mr Z?) is not exactly butchering a pristine 911. Instead, this automotive Dr Frankenstein has taken a written-off 996 Turbo, the victim of an engine fire, and brought new life to it, keeping the four-wheel drivetrain, but shoehorning in an LS1 lump.


Yes, some will call it sacrilege, but this car was only going to moulder away to nothing - and it was a Tiptronic anyway, so it's surely better this way.

Mr Z hasn't finished the project yet (there's at least a rear bumper yet to go on), but you can have a look at progress so far in the videos posted below...

With LS1's as cheap and attainable as they are over there it really sort of makes sense.

A half decent h/c setup should be making an easy 470-500hp all day every day too. Slap on a nitrous kit for an instant 150hp boost too.

Wonder how the handling is affected though, anyone know how heavy a Porsche H6 is including all the turbo's and intercoolers?

Dont know why anyone would use the word sacrilige, its only a Porsche 911, not exactly massively rare or significant in the scheme of things, fitting the LS1 makes it a more interesting and it is indeed a good use of a damaged car, the LS1 is generally well regarded and I would imagine produces similar HP.

Would love to hear what it drives like in comparison, would imagine it changes the character somewhat, its just whether it beign a taller engine whether it makes any difference to the handling, cant imagine it makes that much difference though.

Will post pictures of my Ford V4 into 2.7 RS transplant soon biggrin

It's already flawed enough with a low COG lightish flat-6, I can't imagine how light and floaty the front end will feel with a big V8 all the way back.

Do you have the weight difference to hand? I was under the impression the LS1 is pretty light.

Saw this at Geneva last year. Also a 997 based V8 conversion, by RUF

Dont think the LS1 is all that heavy in comparison to the Porsche engine, especially as the Porsche has 2 turbos and associated plumbing bolted to it, most of the weight int he engine is in the crank and bottom end which will be in a similar position to the Porsche engine, sure the V8 is taller but I dont think it will be enough to turn it into some evil handling pig, Porsche have designed out most of the impact of the flaws.

I think the front end will cope ok as it is weighed down with driveshafts and diff, I wonder if the factory stability control etc is still working ?

Sounds wonderful, but do wonder what it will drive like, how about a ZR1 transpant??

It's nice to know that, regardless of race or nationality, when you see a mate making a pigs ear of something (the donuts in vid 2) then it's universally accepted that you have to laugh at them.

I can't fault the ambition do do the transplant and the apparent success.

However I really don't understand why.

It said it had been fire damaged, would be a shame to scrap it, basically a new 996 Turbo engine and the multitupde of pipes and wiring were probably prohibitively expensive and spare units arent exactly growing on trees for reasonble money, LS1's are comparatively easy to get hold of and plumbing wise a lot simpler I expect.

Did you notice that in the bottom video they had just painted the tank next to the building? If you watch very carefully between when the car leaves and when it comes back (almost all the video apart from the fascinatingly long build up), you can see the paint drying!

No but I assumed the V8 would be much heavier. Happy to be proven wrong though. And in which case, that'd be good news for the car's handling.
