Hi All,

I have fiddled with my Z3 (pic below) and fancy dropping a V8 in for a bit more grunt. I want the torque and easy driving rather than a race or track car with screaming revs. It is a 1999 2.8 at the moment but I thought that 350-400bhp V8 would make it more enjoyable.



I was looking at some American lumps but was worried they would be seriously heavy and screw the handling. Googling suggests the M5 V8 won't fit. Any ideas for engines that are small, light, V8 and would fit?

Might have access to a cheap Lexus V8 which I could drop a turbo on it but I through myself at the mercy of your greater wisdom.

MonkeyMatt - M5 V8 won't fit apparently

LS3 will and is currently top of the is

Might have access to a 4200 Maser unit which is tempting but I dont have the dimensions yet

more pics? - From concept to creation : http://www.madabout-kitcars.com/forum/showthread.p...

Looking at the N74 to keep it BMW but need to check dimensions. There are a few threads of LS3 swaps but nothing for the V12.

Still struggling with the prices of EU engines compared to the LS3 even when factory tuned to 525bhp
