EVO Green vs GT3071R
Well see the thing is yes the GT3076 is a step up from the Green...how big well not huge. On pump gas the GT3076 will easily be over 400whp with the right supporting mods and cams. Race gas 500whp is doable. Most from what I have read and reviewed is you will post about 20-30whp more on pump and about 40-60whp more maxed out on race gas. Of course you will add about 500rpm spool and less torque but one thing to remember the GT3076 will hold its powerband much longer. I have seen similiar dynocharts of similiar mods and a GT3076 made almost 80whp more at 8000rpm versus the Green. The reason you dont see whole bunch of people using this turbo is beyond me but everybody goes to either the green or jumps to a GT35. Most people choose the Green because its bolt on and makes good numbers on pump....the only other comparable turbo is a 50trim and that still cost $3500 or more for marginally any increase on pump. Too me I believe for a stock engined Evo that doesn't rev past 7800 the GT3076 is probably the best *kit turbo* for all around. Basically if you can hit 10.8's with the green a GT3076 would be likely to hit 10.2-4's. Too me a GT3076 to a FPGreen is about what a stock IX turbo is to a Green. Bang for the buck nothing is going to beat the Green plain and simple...unless a FPRed comes out that is 
Well yes seeing as I meant an average of 60whp gain. I believe with the GT3076's ability to hold higher boost more efficiently and showing 80+whp gains in high RPM's with race gas I believe another half second could be knocked off.
dbsears87, I think what you stated is close to what I believe also. As far as the Green's times, and as long as we're bench racing, I think we'll make 10.4's before we quit with it. We already AVERAGE 41whp more from 6000 to 8000 rpms than we did when we ran the 10.87. Those numbers were based on dyno runs on Buschur Racings Mustang Dyno. With those power increases, better 60's due to the 10.87 runs being made in 40 degree temps, and some weight reduction, we should easily hit our goal of 10.5's and very possibly a best of high 10.3's. The power is already made, no bench racing there. That puts us very close to your estimates for the 3076. As far as the 3065, its very nearly a 35 since it is actually a 65lb/min turbo vs the Green being a 47-49lb/min turbo. Street spool would be dramatically different between the Green and the 3065. Not at all a fair comparison. The 30's we're talking about here are the 3076 which flow more like 55 or so. As long as you made the 3065 comparison, however, Jrod's also ran 10.8 at 131. That's a 65lb turbo vs our Green 47lb'er which also ran 10.8 at 128. That puts the performance of the Green in proper perspective. The mph difference is due to the 4th gear, which has been proven to be about 3mph diff. I'm sure we'll see the GT3076 be used more in the coming season, as I think there's a 'hole' between the Green and the 35R, as they are currently being used. I would like a turbo to hit peak torque at 4000 and still make 525 whp on the Mustang. I think we'll see something like that this year.

Zeller, I understand what you're saying. At the same time, OKIX and I are just like every other person with Evo's. We buy every part ourselves, tune the car ourselves and are no different than anyone else is. We just chose to push the turbo to it's limit. My point is, I continue to hear about how the 30 WOULD make more power if SOMEONE chose to do it. So far, no one is choosing to do it. Rather than just make an assumption about it, it's time to see it done. The Green is now proven, either by our time and money, or by someone else. I feel 100% that the GT3076 COULD make more power, but when is someone going to step up to the plate and do it. I'm not talking about Dynojet numbers at a peak point, then not backed up on the track. 445whp on a Mustang ran 10.87. Lets see a GT3071 or even GT3076 do this. Name me one that's run 10's. I can't think of one, YET. I hope to see one, maybe even us. I've always said, I don't care what it is, as long as it performs. I think the GT3076 is a nice 1 step up from the Green, but no one seems to be doing it. Who's running 10's with a GT30? Forget the choice of fuel, boost, yada, yada, yada. Just do it. No excuses.
I understand what you are saying and agree that no one has pushed the gt30 to the limits. I hope to attempt to do a little of that this spring with my GT3071R even though I won't have all the parts and am set up more for road course's but I am going to get a fully pushed to the limit tune for drag also. I agree that the green is a proven and good turbo, I just get tired of people saying the gt30 isn't any good when I do believe that it is a very good turbo just nobody has use it to its full potential. Also so many people seem to think that they put a green on and be in the 10's, when OKIX's car has had lot of work done to it to get it there (and good driving, which can be hard to find). Also, I have a lot of respect for what you and OKIX have done to your cars "by yourselves", it says alot!!! Anyway until a gt30 gets maxed out all we can do is talk.

Spools up faster-yes, green. Power up top-GT30. So essentially a maxed out gt30 should catch the green. A properly set-up gt30 shouldn't spool that much slower than a green (depending on what size gt30).
the gt30R will spool noticeably slower than the green, ALOT slower honestly.
we just tuned a 50 trim, and spooled a TINY bit slower than the green, but ultimately made the same torque, but made 40 more whp at the same boost. Granted the car went to a 3.5" exhaust when we did the turboswap, but i think all that did was hurt initial spool a little....
just some thoughts...
the green is a nice turbo, and performs well, especially on the street,
but I also agree, that a 30R has never really been pushed to its max, I know we havent pushed one.

If you search in another current thread("CBRD and ETS build"), in this same forum, you may very well find the answer to your questions concerning the origin of the 50-Trim kit in question.
