BM WORLD 1283 Report post Posted June 17, 2010 you could just the e34 535i engine with the complete e28 535i wiring loom and ecu etc . swap all teh manifolds and other bits other. also you will most likly have to make up some new engine mounts as the later engines dont have the casting for teh old mounts etc e34 535i has less power and torque because it has less compression than the e28 engine . i have a good e28 535i 10;1cr engine sitting in my shed , had a newly built up head on it etc before i removed it and fitted a m5 engine.
