Default into an S-car????

Alot easier than Marc's swap. You can pretty much buy everything you need to get it in, Marc had to fabricate motor mounts. The 4.2 V8 was available in the S. I believe that plumbing would pose the biggest challenge. I would use the 3.6 exhaust manifolds, and a pair of k03's.

Default I would have guessed engine management as the most difficult part.

But fabbing custom exhaust and intake would present some problems, too. I've read all of Marc's doings on Motorgeek, and have been pretty seriously impressed. Mostly with his patience. You can't be in a hurry for that kind of project!

LOL. I'm going. The Glen, Tremblant, NHIS with ACNA, then 2 days in November with PDA at LRP.

I imagine using the 90 was the biggest problem. This would either be in a Z or a C3 V8

Default I've already picked out my next daily driver/project

a few years down the road:

S8 with a 6 speed tranny, custom intake manifold with integral water to air intercooler and a supercharger mount on top. I bet I could sell a few in kit form

Default depends on one's definition of "challenging." It's better to describe process and work necessary

for the project rather than just discount it as impossible across the board.
