Try Nasioc.com NoOb

 

Won't be able to do it with just more airflow, He's gonna need a good engine management setup to get the fuel and ignition timing to work with the extra boost pressures and airflow, with out aftermarket fuel control he's gonna blow his motor real quick.

 

 

Also, does he want 400 at the wheels or the crank?

He's also going to need air flow out, new up & down pipes.

Cobb makes some nice stuff, i think they make wrx stuff too.. not exactly sure... the access port will give you a little more nut.

Trade it in/sell for a 04-05 STI and then modify that lightly.

 

The most modified WRX will never hold a candle to an STI no matter what transplants and frankenstein jobs you do.

400 whp is tough even with the new 2.5. I would say he'd need at gt series rotated turbo or the UR t3/t4 kit. Very nice kit IMO. Anyway. Bigger injectors, fuel pump, rails, Intercooler FMIC most likely. It will almost require a better trans and clutch. Also bigger Turbo back exhaust and a ext wategate setup, headers. Also like said earlier good EM and someone who can tune it.

 

 

he's looking at 10k easy juat so he knows.
