I am ripping my L26 down to the bare components and building it up with high performance in mind. I was wondering what effect going up .020 in piston dia. would have on the overall torque and HP or my particular engine. I would go the full .040 but Motorsports Auto doesn't carry any aftermarket pistons anymore for the L24 or L26. Also, I would love any other suggestions on building my engine ( other than superchargers and the like).
