Can i make 400 HP with a GT28RS and my motor and tranny be ok its a 98 A4 1.8T 5 speed

 

no way man. u need a gt30 turbo, rods, intake, exhaust, stage 5 clutch, chip, injectors, BBK, manifold maybe, and maybe new coilpacks. there's prolly more u need but that's wut i can think of off hand.

 

Is someone creating a new user name and just posting the same thing to bother us? SEARCH please, this is like the 12th turbo question this week. I doubt you could get 400hp with a gt28rs. Maybe maybe maybe if you got some agressive tune and did evey supporting mod you could get something like 380 at the crank. There are a bunch of people who know better than me. If your lucky then will chime in but their probably as sick of this question as I am.
