ATP Turbine Housing, T4 Divided inlet 3" V-Band outlet, 1.06 A/R (Version 2 Model) for GARRETT GT3582R/GTX35R. How much would this help a gt3582r with t3 inlet produce power on a powerlab setup? Thanks in advance. Would moving up to the t4 inlet increase the flow to allow for more boost resulting in increase power?

 

You will need twin scroll exhaust manifold system to take advantage of T4 divided turbine exhaust housing.

I would say it will help some, but for high power numbers you should step up with turbo size too.

 

I would say yes. TQ may drop off and actually make the power band safer if your not running a built motor. HP should increase

 

While true alot of supra guys run divided turbos on non divided manifolds running a quick spool valve.
