Just tryin to get some info....I have SR stage 2 single turbo kit and I think I might go smaller for better response....lookin for thoughts on turbos.....thought about the t78

 

How much power are you looking for? RX6, GT35R and GT35R(T4) are all good choices if you are looking for quick boost response and 380-450 rwhp.

 

well if i could get a turbo to run me in the 11s to mid 11s i would be real happy.

 

A-Spec GT35R T4 for sure, or go with A-Spec's new 500R kit
With the T4 I made 436 at 16psi, 16psi by about 3500rpm give or take a few rpm (damaged turbine wheel)
With the 500R I've made 448 at roughly a bar thus far at around 3400-3500 rpm and around 250ft-lbs of torque below 4k

 

Thanks I will start doing some research

Also did an unofficial run with the 500r and made 503 at 20psi just fyi or at least that's what I was told by the guys at A-Spec

 

old school and much cheaper 60-1 or t04e 60 trim can get you into the 11's with full boost between 3300~3800 dependant on set up (manifold type, port work, tunning etc). Of corse, the GT35R and the gt35r t4 variants can do the same and hold more potentual to make more power (close to 500) for added cost.

^ depends.
i fit's a t3 35r, i'd rather go with a t61, or something in that area. the t3 turbine just chokes it out up top. the t61 is a very similar compressor, but with a p-trim, you can really taylor your spoolup vs. hp by changing the a/r.
