Well I am looking for good streetability on stock engine internals and stock 37cc injectors for at least the next year or two. I'm not getting turbos as an upgrade, i am getting new turbos b/c mine blew and getting some sport 500's or the Z1 ones are about the same price as the upgrades but the upgrades have more power, but they will run at now higher than 15psi for a few years till I get out of college
