Anybody know the compression ratio for the S50B30 (E36 M3 3.0ltr) engine?

Ive seen 10.8:1 mentioned before but just want to make sure.

Cheers

iirc that's correct, and 11.3:1 for s50b32 (100% on that)

James,

10.8:1 is correct for the S50B30 (just checked the TIS)

Cheers,

Ian.

And as I may have the chance of another 3.0ltr S50 it would be rude not to make a few plans :twisted:

Heh - I haven't got a copy either. I remember a friend of mine sending me a link a few months back, as he has a 96 M3 coupe 8)

Just proves that BMWs can be boosted quite hard really. Having said that, any more than 350bhp in an E30 would be on the scary side of excessive 8)
