How do I upgrade? If I get a set of pistons that gives me 11:1 cr, what else do I need to upgrade??
if you go with that kind of compression you'll want cams with big lift and duration to take advantage of it. along with the cams you'll need a better valvetrain to keep up. if you go with a setup like this you should keep it all motor. you'll also need tuning and run nothing less than 91 octane.
