three m10s.
Stacked on top of each other with real long belts.
I would get what's his nuts to fab me some crazy carbon fiber hood.

500ci AMC by INDY cylinder heads. Or some Ray Barton HEMI (with the cross ram setup)


Why?
I like the thump of a V8.

I agree with you there, although I think I'd prefer either the overplayed LSx idea, or for something fun if weight wasn't a worry a Ford sideoiler.

Personally, I would go with a 5cyl Mercedes Diesel.

[e34john]

what about the bmw p83 f1 engine? :)

I will take a p86 and get it rebuilt every other month. otherwise something like a M88 would be cool.

[BrewCity11]

All-motor S38 in the "original" themed E30

and an LSX in the track E30M3

Do it

Seriously though..probably an LS motor

I had seen a complete drivetrain, ecu and everything for sale for $1000 on craigslist over a year ago, which is what gave me the idea. I think it would be sweet.

What's the torque on those diesels? After modifications? I faintly remember someone saying that they push over 300 ft-lb, but I don't know.
