Yeah the problem with lowering the dynamic compression (VTEC, valve overlap) on a FI car is you just blow your air and fuel out the exhaust valve becuase of the boost.
Hmmm. I'm putting together a Honda H22 block right now and the cams that we're probably going to use are the Crower turbo grind cams. The specs look almost identical to the stock cams but the duration looks shorter on the Crower exhaust cam vs the stock one. IIRC, the lift on both the intake and exhaust is just marginally higher on the Crowers. It doesn't really seem like that much of a difference over stock specs though.

I wonder why a four piece block is stiffer. I guess we'll have to wait and see.
So what are the four pieces? The older engines used a basic block, finned cylinders, and heads. Seems like the less parts the better?
