Opinion on best or coolest motor swap

[lambo]

rotary all day

edit: not an e30 but definitely one of my favorite cars of all time

I voted 4g63 because I like those LOL anybody got a link to a build?

Epic no budget bimmers deserve the v10. It's like the M156/159 AMG equivalent, you won't ever be able to keep a straight face when it blasts your car sideways.

S70 if it wouldn't ruin the fun of driving anything else.

Well .... if we are going total pie-in-the-sky here.

M70 with IDF downdraft carbs and 10" chrome stacks through the hood.

Slightly less wild option .... same idea with an M30.

On second thought , a vr6 would actually be a cool swap.

Because slower than s52, and really hard to make it work?

N52: 260 hp and less than 350 lbs..... ugghhh

+1 on this!

+11. Seriously under rated motor. 275-280 is fairly reasonable with a tune and headers. My 330i put down ~224whp stock..

I have been contemplating a 1j/2j swap for a little while now.

As far as insane, I 2nd a Cummins swap. That would be incredible!

Lightly used Roush Yates 358 D3 NASCAR engine. I think that would be reallllll nice.

I think you should drop a bfh-8675309 in there. It would be sooooooooo epic!!
