if you had your choice between a GT3571 http://www.turbobygarrett.com/turbobygarre...71_731413_1.htm

and a t04e "60"

http://www.turbocharged.com/catalog/compmaps/fig16.html

for a setup shooting for 350hp without a whole lot of lag.

o and this would be for a s5TII

Any other suggestions on turbos that i should consider would be appreciated. Thnx

personaly go with a t70 or atleast a to4s. both the t70 and the to4s spool qwick and have a much broader power band. the gt3571 and to4e tend to fall off at the big end.

GT3582R with a T3 exhaust housing. The Falken FD makes 518 at the wheels at 22psi with the same turbo (just retuned Monday). It runs a .82 A/R hotside. Starts to make power at about 3800rpm and the hp peaks at about 7500 and torque peaks at about 5500. It also makes 442lbft of torque. I would say that 350 at the tires in an FC with that turbo isn't too hard and would provide a nice powerband.

The to4e especially the ford heavy truck version for about 700.00 is pretty good bang for the buck. Mine did 365 rwhp at around 13 psi on an s4 with a 1.15 a/r. on 91 octane.

Why not spring for the GT3574 from A-spec? Only 900 bucks, and is capable of big numbers as well.

Or you could always upgrade your injectors and go with Brian's stage 3 bolt on upgrade at http://www.BNRturbos.com

Hes getting like $775 for the upgrade and told me his FC is making like 350rw. Very pleasant to work with and a real cool guy too.

At least that is what I am going to plan on in the future. 4x720cc's and a stage3 from BNR Supercars.
