Can any one tell me the max psi on vitara pistons and race boy rod set up? Im looking to run about 15+ psi. Before this i had 7psi on stock internals and ran chrome, think this time my set up will be s300, 15g turbo (volvo or dsm) and DSM 450cc injectors. The big deal about the turbo to me is putting a external waste gate on, any easy way around this? Or should i keep the stock waste gate? Dose this look like a good setup?
