Hey guys, Which turbo kit are most popular for WRX? Or any suggestion for custom? I am looking for 350hp daily drive. Thank you
for a turbo upgrade, i'd recommend the following supporting mods (you may already have these): fuel pump uppipe turboback exhaust engine management upgraded intercooler (not really required but i would recommend it) i am assuming a 25% drivetrain loss... that would make 350 crank hp == 262.5 whp 2002-2005 wrx: 350 crank hp: vf34, vf39, vf22 should all get you in the ball park with proper supporting mods (all the above + injectors) 350 wheel hp: you will probably need an 18g or bigger and methanol injection 2006 wrx: 350 crank hp: you could probably come close to that figure with the stock turbo and full exhaust... 350 whp: i'd say 20g+injectors should be able to get that on 93 octane crank hp is just an estimate... wheel hp is more of a measurement, the accuracy of which can still be debated
