James, even with kyles intake the head flows only ~180cfm and the stock manifold is said to flow 240cfm, IIRC.
Today i got taken for a drive in a ta23 with a 1g with the same turbo I have same microtech etc, intercooler etc just a smaller rear housing. at 16psi the setup produces 240rwkw, which is more than enough, I also will be using cam gears which he did not.
Craig (the guy who took me for a drive) retains his TVIS, I will be also just with the 4mm screw mod to the number 1 and 6 runners to enable even flow (kyle himself notes a 10cfm differential betwwn the other runners and number 1 and 6)
