Investigating a 325i engine swap

If anyone knows, what is approximately the largest displacement engine that can be fit into the engine bay of a 1986 325e? (with some modification if needed)

Various performance parts manufacturers (alpina, hartge, etc) have used 3-series bmws as a base and put some ridiculous engines in them.

I'm looking to produce some kind of ridiculous power-weight ratio.

m 50 motor, best mod 2.5 liter out a 325 i e36

No, i mean what is the largest engine displacement in cubic inches. I'm not only looking at bmw motors.

not sure but if you want a nice race spec motor talk to the guys at turnermotorsports.com ask about seimens motor 330 hp in your light car will be verry fast. they can give you measurments in cubics too.

I'll check it out really quick.

In the meantime, think of how a 1986 325e with a full e30 m3 bodykit would look with a Roush 550hp v8 w/highrise induction sticking out of the hood.

If that wouldnt win the show, what would? =)

good luck man , going to be alot of work .... and money, that would deinantly catch stares. if you do it i would love to see it, that would be nasty:)

I'd like to stuff a Keith Black Hemi in my Iseta.....if I had one.......either.......or.............
