How much compression can our 5sfe cyl-head handle as far as pistons and decking are concerned? I can't decide on 9:1, 10:1 or higher?

No turbo at for me...so what would you choose for an option then for comp. ratio? I would like to deck the head like you mentioned (not too much though)... thanks guys! |
