thicker head gasket, port and polish the head, air and fuel ratio <-- important, check oil often<-- dont run too dry or too full, valves and springs upgrade, cams upgrade, port and polish intake manifold, upgrade throttle body 68mm should help, get s-afc, dsm 450 injectors, if on the budget dont touch the block yet.. once u start on that it's going to keep going.. with all that done run 7psi daily, 10psi on the track once in a while.. repeat once in a while, and dont try to rev too high.. keep it around 8500rpm <-- u kill ur engine faster that way on turbo unless it fully built to rev to 10k
OH yeah, also, don't listen to free advice on the internet cause every clueless dickwad feels free to levy their opinions.
