turbo gurus ?
 

I got a street ported s5 that Im going to use for the track(road course), I want a turbo that will spool quickly, hence track racing but, I also wanna be able to make 400+ so I can have my highway fun every now and then, what do you guys recomend?

GT35R, Apexi RX-6, A-Spec 500R

t3-t4 hybrid or t60-1 with 95AR, imo. Since you are street ported you dont need a huge one to get 400 hp.

60-1

for fast spool I would say gt35r or 500r like classicauto mentioned. Only problem is unless you have deep pockets then these turbos can break the bank. The 60-1 is a good turbo as well like node said that should get you that power at relatively low boost 16-18psi of boost. This turbo is a bit cheaper however you have to also look at everything you will need to go full turbo upgrade like wastegate, manifold, oil and coolant lines, downpipe, ecu, injectors, pump, alky injection (if you want reliability), etc.. etc.. etc.. If you want close to these hp levels for less than a bnr hybrid turbo is the way to go. With one of these turbos basically you can bolt it right on to all the stock stuff and go. Of course you will need suportive stuff like injectors and ems but then you don't have to buy everything else. go to www.bnrsupercars.com for the turbo info.
