I have a MY01 WRX, got hold of the following parts and are fitting them next week:

STi7 turbo
STi7 Intercooler
STi7 Injectors
STi7 Bonnet scoop

Already have complete de-cat exhaust system, upgraded fuel pump, ITG panel filter and will be getting another re-map.

Is there anything unobvious in the engine bay that I should also be fitting? For example will the WRX dumpvalve be OK with the STi turbo? Please advise, thanks.

 

ECU?

I would check with the experts on this, not sure how the stock ecu will react with different injectors and turbo etc...
