1.06 T4 sounds huge enough, but because it is a twinscroll housing, it isn't overly large. Also, FWIW, it is the smallest readily available T4 twinscroll housing that fits a 35R turbine. I have one on my 2.0L with HTA 3582R (a 700whp turbo), and I see 20 psi around 4000 rpm.

I'll be 100% honest...I can almost count the number of people running our twin scroll stuff on both hands...Every single person i've spoken to loves it. We are running a similar turbo (gt35r 1.06ar t4) on our Evo X. Inital tuning shows 20psi by 4250 ish and i think there is some more left on the table...

Why is that that people think that no one can make a properly made, precision fit manifold that will not lose performance. All of the AFI stuff I have seen was flawless. The flanges are all machined if I remember and look great along with all the welds down the manifold.
