Hi Zroadster.org, I have a 98 2.8 Z3 with AFE cold air intake, M50 inlet manifold conversion (including widened throttle bodies) & Schrick cams, Eisenmann exhaust + remap. I was wondering if it was feasible & worth while to bore the engine out to 3.2L & what would I need...I am looking for maximum power from normal asperation. Apart from new pistons/rings...what else should I be looking at? Upgrade Crank/con rods, valves etc...have not decided yet...just thinking...any views? I don't want to put in a different engine or change the car. Just maximize the power from the existing engine.
