2.5 or 2.7 conversion???

[e30bmlover]

hi guys. as you are all aware i have my sweet 320ise nearly mint, i want her to have a bit more grunt, would it be possible to do a 2.7 conversion on her????? my reason is....... the body is immaculate and if i buy another e30 i can almost guarentee that it wouldnt be in as gooder condition.
how big is this job to do???? what parts do i need? and how mutch will it cost?????
any input would be appreciated!

i have an 87 320i, and i have just dropped in a 2.7eta engine.

id definatley recomend. both engines are jettronic.

easy to do and fairly cheap.

dunno what jettronic is mate. just need to know what parts i need to do it, i want a schnitzer cam also. do you need a different e.c.u, i thought they just bored it out and put bigger pistons in it.

Cheap and easy version is to get a complete bottom end from an E28 525e, fit it up with the motronic engine management sensors and complete top end from your 320, all of which should bolt straight on.
A slight improvement can be had by using a 325 throttle body and inlet manifold, with the 320 ports matched to the manifold.
I have all the above parts in my workshop, just waiting for some spare time for assembly.
A better 327 can be made by fitting the 2.7 crank into a 2.5 block with a 325 head, but there's a lot more machining and other parts needed for this one.

so the first option is to get hold of the 525 bottom end, what bhp will i get, and what ecu??? shall i get a performance cam also.. i,.e schnitzer?
