If ur planning to run more than 8psi with ur stock internals, well i suggest u do ur bottom end. Atleast by putting rods and pistons u can run more boost and u wont hurt the engine even if ur running stock head. Other things u should do before u put the kit is get a tunable ECU, maybe change the injectors and fuel pump to gain power. With that set up engine will be safe and should go well![]()
