i had the greddy kit on my car, outta the box with the large greddy front mount i ran 8lbs of boost, towards the end i had a stock bottom end running everyday on 14lbs of boost, put out 280 to the wheels, so i think thats about 350hp, i beat the 3 jrsc'd tegs around my area, was definitly better then the blower in the long run my mods included a 3mm head gasket, afc, avcr for boost among other things, and a long dyno morning
