my car will be my daily driver with occasional autoX'ing. So i want to keep it streetable (which rules out a massive turbo like a T78 or T51 KAI). I am also infatuated with the V-mount setup. So any other opinions?

I make 400RWHP with the GT35/40 Spools quick compared to larger turbos that are capable of same or more HP. Dual ball bearing cartridge. Garrett GT series Turbos are top shelf components. Make sure if you get the Garrett get the 1.06 A/R exhaust. You should be right at 400 RWHP@15psi with similar set-up as mine. I made 404.2 RWHP on a stock reman motor with this turbo. I am now installing a Street Ported motor that i hope will make close to 450 RWHP@15 psi. The GT35/40 comes in a smaller A/R .86 as well so you would get full use of your low end power for AutoX. It will still make 400 hp but probably not at the same boost as the larger 1.06 A/R.

the v-mount from rotary extreme i *believe* is most efficent around 15-16psi. not 100% sure on that. How long will it take to get 15psi on the 1.06 a/r one? btw, what does a/r stand for? im a newb to singles.

I am shooting for 400whp on a stock s5 t2 block at 15-18lbs on 91 gas with a to4s. I have seen plenty of 400+whp with a to4s at that boost, but not on a stock block.

HEY I made 410 rwhp 335 tq last week on 17 psi with an old diesel turbo modified by me, at 3800 rpm my tuner said it explodes with torque at that speed and goes to 7000 rpm quickly. lightly ported, 2 mm seals, stock block, street vehicle, 1500 rpm in 5gr. pulls smoothly no problems, on the street its torque, on the drag its hp. thanks Ron
