You will probably need :-

Unequal length manifold and up-pipe.
Ecutek re-map.
Up-rated fuel pump.
Full 3" de-cat exhaust.

But you may not reach 360/360 on just these bits.

You MAY need a larger (front mount ?) intercooler.

IMHO

DunxC

 

you'l be lucky to get 360/360 on mods alone

ported headers and after market up-pipe (ask harvey or api)
Up-rated fuel pump.
Full 3" or 2.5" de-cat exhaust
Ecutek re-map
ngk7 sparks
port turbo(optional depends how far you want to go)
intercooler you'l be fine with

will get you between 330 to 360 bhp to up bhp and torque more think of adding meth
