if hes not sticking with ct9 tho half of them mods are wasted mate
dont forget some good rubber
new oil/fuel filter
uprated discs and pads
whiteline rear arb (anti-rollbar)
full exhaust system including decat and manifold
fmic
hks actuator
greddy emanage
that should see you running 1bar on the ct9 safely,making decent power and handling sorted too...shouldnt be far off a grand
after that see where you wanna take it...maybe add a few more struts and up the power
