Non-Vanos Head w/ 2.8L Block?

[raimo]

Can i use M50B20 parts on M52 block+head ? except the intake and exhaust manifold of course. they are virtually the same with the 2,5l engine

Dan, yes. Big jump in stroke, you'd go from 84x75 to 84x84 ! The 2.8 crank is forged to boot.
And the 2.8's have those nice graphite (or ceramic?) coated pistons.

Are the non-Vanos M50B25 rods the same length as those in the M52? I know the non-Vanos rods are extra beefy, y'see...

All M/S50 rods (US atleast) are 135mm, the only exception is VANOS 325's (93-95), which are 140mm.
Same for M20's too, 135mm, exceptions being the 325e (130mm) and the 320i (also 130).
