i have an s4 b5 i wana upgrade my turbo but i wana get about 500 wheel hp i here t28 and t35 garret turbos are good any one have any advice on what would b the best turbo to push me to 500 if not way over i wana b able to no i can get alot more out of the car if i want

 

your going to need more than just a turbo lol....

 

you can get 500 whp out of rs6's on stock internals, probably out of gt's as well but if your going gt's you might as well build your engine and your heads.. go for 700 whp.. you can get about 400 whp out of an aggressive k04 setup with dumps, meth and such, but youd be pushing it.. anything more than 450 to 500 whp you need to get new rods..

you need to check out the s4 threads and search some similar titles, theres a ton of info in there..

 

thnx for the advice dude also im planing on boering it to a 3.0 if the block is able to handle that i gona upgrade all the intrnals and everything
