DP3,
I'd be interested in the 52 trim 3037/3076, I've held off buying a turbo [for several reasons, $$$, hunting down a HKS cast manifold, getting it honed and coated etc], but would be very interested in this turbo set up for my RB25. I can wait a bit longer, but would have to reassess my options if March drags into april into may etc. If Garrett have them out by March, the timing would be spot on.
BTW I'd be looking at an external wastegate, but if they are internal then I guess I could plate over the external mount on my HKS cast manifold. But an external wastegate should be no big deal because the changes are on the comp. side, not the turbine side.
