I have a 03 max engine stock....
Looking for opinions on bolt on performance parts.
Heres what i have planned to start modding
Cgr gutted upper manifold, gutted elbow, shaved lower manifold
Cgr 3" intake
75mm big bore throttle body
Injectors (need help & more info on what kind to use)
Underdrive lightweight pulley

Once thats done gonna do full headers/exhaust setup

Am i going in the rite direction w/ the build? & what other bolt on mods is good & can be done?

Thanks in advance
