If you could use any engine in the E30...

20b or 27b rotary.

Aside from the unobtanium F1 engines, I'd take a built N/A S38 or S54. Only non BMW engine I'd put in would probably be the hayabusa-derived V8...for some reason LSx swaps just don't seem right to me.

I think I'd do an LS7. Hand built, dry sumped, outlandish power, all aluminum, heads are 8V each so they're very compact and lower the car's CG, and a longblock can be ordered from jegs.com.

turbo s54 or s62...

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.

N47D20B
2.0L twin turbo diesel, 204 HP... gets 45-50mpg in a 1 series, even more in an e30..

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.

All-motor S38 in the "original" themed E30

and an LSX in the track E30M3

[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.
