rbs14kouki: the T4 flows a little more air than the T3. Full Race sells T3 and T4 flanged versions for the SR20DET. Their twin scroll T4 manifold is for the big power players.
The one I have is a single wastegate but has a GT4088 mounted to it, and though the original version may have been a T4 single wastegate, their current single wastegate version is a divided T3.
Anyway, I have a tentative deal in the works for a GTX3076R for which I will be buying a .82 AR Garrett divided T3 housing. This should make it as responsive of a setup as can be had in at a 3076 power level.
From what I have read, the GTX3076 will spool about 300 rpm faster than the standard GT3076R, and when combined with a divided T3 housing should make it spool as quick as possible.
I should have it all built and installed in about 3 weeks, then custom tuning on the dyno. Maybe I will have a dyno report by the first week in February.
