Evo X bolt on Garrett GT30R turbos
Lookie what popped up on the Garrett website today:

Based on the numbers posted on the garrett site above, the 3071r looks to be a 47 - 48 lb/min offering while the 3076r looks to be a 52lb/min. I think the main differences between this turbo and the Dom / Red series would be seen in spool and top end power (hot side should flow better than machined stock housing used on the Dom / Red.)
Two MAJOR differences between the Garrett offerings and the FP Red/Blouch stock frame turbos: bigger A/R turbine housings and ball bearing CHRA. Oh yeah, also the ported shroud compressor housing so that you won't get surge like some have reported on the Red.
Both the 0.73A/R (GT3071 option) and 0.94 A/R (GT3076 option) turbine housings on the Garrett are bigger than the stock turbine housing. As you know, if you want to make more power, you need the bigger turbine housings.
I'm going to make up some numbers to illustrate, i.e. not exact by any means, but to get the point across. With the FP Red, you'll probably see 40psi of back pressure in the exhaust manifold. If you have 40psi in the exhaust manifold, and 25psi in the intake manifold and both intake and exhaust valves are open (overlap), which way do you think the air will flow? With the 0.94 A/R housing, maybe that backpressure in the exhaust manifold drops to 25psi.
This is mostly why the FP Red is only good as a meth/race gas turbo, and not so great on pump gas; the turbine housing is too small. Another thing with the Red, I'm not sure how well the turbine wheel mates up to the turbine housing, meaning it probably doesn't fit 'optimally'.
So with the Garretts, I expect the larger turbine housings to slow spool some, but the housings are designed to fit the turbine wheel properly, so I think that will offset some of the lag. Also, the dual ball bearing will offset some lag also.
My GUESS is that the 3071 will spool faster and do the same as the FP Red on pump, and the 3076 will be a little slower but make more power on pump (and maybe race gas as well).

If you do a search for distributors you get a list of Garrett turbo suppliers. D&W actually even has an office locally (Rochester, NY) but I'm not sure how much they have dealt with Evos. I would rather support a company that deals with a full lineup of Evo X performance parts if possible but local is good too. Likely I'm going to install this by myself but Street Tuned Motorsports would be another good option.
That's why the 3076r has my interest! I plan on getting my Exhaust manifold extrude honed or maybe a stock positon tubular setup although I think the former would have 90% of the power gains while retaining the stock heat shield. Getting an AMS or Ultimate racing O2/DP combo pipe, 1000cc injectors, and a fuel pump upgrade would complete the setup.

Very nice I'm getting excited. It's between the twin scroll gt3076r, fpred, or a TS htagt3076r(best of both worlds as long as there's no surging. But the most $$. I'd love to see some numbers on E85 which I'm planning on running.
