Whats the highest compression I can run with 91 octane in California with out having to retard my timing.
I want to run CTR pistons but i dont know if the CR will be to high for dailly driving with 91 octane. If it is im going to run ITR pistons.
Its going into a gsr block with a b16 head (not Milled).
