The Doc and I might be talking about the same melee, but I think there was a guy doing Buick Grand National swaps in Fieros, who wanted to transplant one into a 986. We have never heard from him again. The GM V-6 might fit. The LS-1? That's pretty big.

Yeah, I kind of threw the LS1 in there figuring it was really unlikely.

You may want to consider a 914 as the donor car as it's been done with a few engine variants. I know Chevy small blocks and Subaru motors have been surgically implanted.
Small Block 914
914 Subaru Conversion
I considered it briefly before I sold my 914 and bought the Boxster.

I think the biggest limiting factor in the 986 chassis is the length of the engine. The boxer 6 is pretty short. You basically have from the firewall to the transmission, which is about 24" or so?
I'd think maybe a Subaru 4 cylinder boxer... with a couple turbochargers on it? Might be able to get 250+hp out of it without too much difficulty.

Oh well, I suppose that would be the problem, as I am sure the I-6 of the 2JZ is quite a bit longer than that (hmmm, although I would be willing to give up the tiny rear trunk...) Perhaps a V6 engine might fit better depending on the configuration, something that is a bit more durable than the stock flat 6.

aside from the engine length and configuration, remember you gotta factor in the tranny too!
go for a x51 3.8L from a 997S and build that badboy up

Yeah, that is true. Now if I had money for an x51, I don't think I would be considering other engine options, but those Porsche engines are pretty expensive, and seem to be only mildly tuneable, which is why the 2JZ would be ideal, since it is probably the most over-engineered block out there and not terribly expensive.
