i would say you get probably get approx 275whp/325lbs w/ a k04/e05... if you want to make more then that you will need to step up into a gt28r type turbo...Originally Posted by AirMax95
honestly i would go k04/e05 + GIAC + tt 225 injectors/maf + 3" dp + 3" exhaust + intake + dv + new n75 + larger inlet pipe ... 1.8t motor is good for about 350whp if it is well maintained
