Yeah, US 87octane. I want to swap my '86 BMW 635csi's M30b34 (8:1 comp.) engine for a M30b35 (9:1comp) engine (0.1L more, and another 30hp).

I'm going to leave it fuel injected and run a supercharger; but I was also going to bore the engine out some and was wondering if more compression was possible with out anti-knock sensors and all the modern gadgetry.
