hi all i will soon be buying a e34 but am torn beetween two 525i or 535i i want to turbo charge on standard internals around 8 psi will be running after market ecu to keep everything nice not worried if i melt a stock engine.

i have read the m50 head flows better and i guess the engine weighs less

hovever the m30 has stock cr of 9-1 and an extra 1000cc but a prehistoric 12v 3 injector set up

am new to bmws am traditianaly a jap man but want something big and intimidating to drive while i build my other car but needs to be quick i would guess in a e34 atleast 350whp to pull off lol


all info and coments appreciated

thank steve
