internal engine upgrades?

[pencil1985]

im thinking of getting the hahn stage II turbo kit, however i know it only does 8PSI on my stock 420A engine which i know there is a reason for. however can i put that psi up on that kit if i strengthen my engine? if so what do i really need. i take it pistons, rods, cams? with those how much psi could i push from that kit? or what would i need to do to be able to push around 14psi or so. thanks

to up the boost all you would need is a boost adjuster. you can pic them up on ebay for 10 or so bux. internal, wiseco makes an awesome piston that comes with the rings unlike je, eagle rods are good to you can pic them up for around 300 or less on ebay and they will support 500+. that is what i have on my setup. i kept my head stock. if you going to be running 14+ psi get the head port polish, i believe crane makes a cam for the 420a. i had mine bored 20 over and no probs.
