Hi there

20G Billet or MD321H/MD321T or SC42 onwards
650cc at least,but yours 550cc injectors should be OK with FPR for 400bhp
Full 3" decatted exhaust
Hybrid or Japspeed FMIC(will be best bet)
GT Spec headers,but yours headers should be OK at 400bhp,maybe Harvey Ported headers should be cheaper bet
Induction Kit,personally i would go with RCM/GGR induction kit
OS remap or EcuTek remap
