i would say 2.5, i do not know much about bmw motors, but i know about high reving and turbo'ed motors to say that once bored out, you will have a rod stroke ratio that will not be freindly on the engine, and would require a massive build up to withstand 15psi reliably.

a side note, if it was me, i would supercharge a m3 motor

chris i looked into this, the m3 motor doesn't take well to boost. It will be more work just to keep it running then its worth... I did my hw on this topic
