ok, do a comp. test, see if your motor is healthy, make sure your not leaking oil or coolant, or burning anything. if your motor is healthy your okay to boost, and if you want to build your motor, then build your head that where all cars make there power, but if you want to be able to run more psi, then build up your bottum end, dont just get block guard, they blow, go read about them, get the motor sleeved and get stronger rods, and low comp piston, there is alot of info on here about building motors for boost... do a little bit of research before you get in over your head
