if we are talking about a uk Sti.
Stock vf 330 max 350
stock injectors 360/370
stock good condition Tmic 400hp
Stock air box with filter good for 400 too
Parts required
Ecu software upgrade cant remember if ppp cars just require tune on the existing file as licensee already there.
PPP full pump or walbro 255+. id thnk of changing if ppp as few years old now,,
FULL 3 inch system decatted would be better but a sports cat in the down pipe will work
turbo such as SC42 or old school 20g
750 injectors not sure if fuel reg required for control
colder Plugs
Tmic will work but is on its limit options are Fmic or v9+ Tmic as larger.
Extras Such as Rcm headers and up pipe, 3port BCS , A Rcm Ind kit, intake pipe, will all help towards making it more free flowing.
