GT35RT4 A'R's?
I currently have a GT40 on my car. .58 Cold, .94 Hot. I am around 11psi by 3600rpm, on the stock port 76k Mile engine, Wich is awesome.
Recently Ive been looking into going down to a GT35R. My Power goals are 350-370whp.
My biggest question is, what will be the best Cold/Hot A/R for my application? This is mainly a street car, with the occasional Track day on a road course.
Engine setup as Follows:
S4 13BT, fresh, with a Heavy streetport
550s/1600s
Walbro 255
Haltech E6k
NPR FMIC
Any insight is appreciated!

Another turbo you can get would be the GT4082. It's a very responsive turbo on a rotary and it's much cheaper than the GT35RT4. It'll fit perfectly with your power goals too.

I appreciate the advice. If you get a chance can you pm me a price for the Turbo/Manifold combo? It has an SS Autochrome Manifold on it, and I would love to switch that out as well.

The 1.0 will give good response and With the RS you will have a much better time up top. Big difference in eff. at 20lbs. 67% versus 75% The 1.06 will be slightly off in response. If I get a chance I will swap housings out on the dyno and I can then show you the exact difference. It's up to you really tell me what you want.
