Ok so I race a EK9, after the last race the headgasket blew so I’m stripping and rebuilding the engine for next years season. I have a few questions. The block needs boring as it has a slight mark so I will need new pistons. Which are the best ones to go for and what compression ratio? I can find loads of b16a high comp ones but I know these produce a lower compression ratio in the b16b. I’ll be using the standard crank and rods but they are being fully dynamically balanced along with the flywheel front pulley and clutch cover. Next is cams and valve train, are the std valves springs and retainers up to the job and what cams are ok to use with them? Or do I go for uprated components? As will the higher comp ration dictate what cams we can use. Thanks.
