i have a b16 in a 92integra. i am keeping it all motor since i've turboed my supra. i want to raise the engines capability of going to higher rpms. what components do i need to get my engine to go up to 9000 rpm? what valvetrain upgrades do i need? what other upgrades do i need? i dont want it to just go to 9K, i want the power to peak around that area as well.

 

if thats the case then your gonna need the ecu chipped, cams, valves, dual valve springs, retainers, and id upgrade the rods atleast in the bottom end just to be safe
