Possible New Upgrade for Greddy Turbo?
First off to start I know there has been tons of discussion of Turbo upgrades, from upgrading the stock greddy with a 20G or a 57 Trim Wheel, to the BNR 60-1 Upgrade to the MM GT3071R. The thing about the 3071R is we don't really know the details of the upgrade(ie: Modifications made to the turbo for it to fit, A/R Sizing and such) and from what I gather he no longer offers it. I came across this turbo while browsing ATP Turbo's site and I was curious if this is possibly a good fit for a bolt on upgrade.
Here are the specs:

So what do you guys think?
Any insight would be great!
Here are the specs:
Based upon the same turbo as the HIGH flowing, larger framed GT3071R, but conveniently packaged into the same style turbine housing as the popular GT28Rs/GT2871R turbos. This turbo is uniquely configured with its own turbo wheel trim, turbine A/R, and compressor housing. Unlike, the GT28RS and GT2871R, this turbo now has a much larger compressor housing to support the much higher flowing 71mm compressor wheel. Comes with T25 style inlet flange.

You are still going to have to modify the turbine inlet flange.
We are working on a Greddy hybrid upgrade; bolt in, water cooled, billet compressor wheel, bigger turbine wheel...

I came accross this a while and almost bumped some old threads on the subject for some feedback but I figured the "experts" would jump in and start fighting and just confuse the hell out of me so I just decided to go another route

some one here long time ago, they use the same greddy manifold, but he jsut made teh extension to the top. so you jsut need to get a new downpipe and discharge..it looks good though because he used the GT25 , somethign like that

The details I was referring to were the Turbo Specs and the modifications made to the Turbo so it would physically fit in the stock Greddy location.
I was hoping to start a discussion that would lead to this information becoming readily available for all of us and to give us the option of using a GT3071R or even GT3076R with the Greddy kit. Basically we need to know the housing sizes that would physically fit, this turbo seems like a good option to me and sounds like it should fit.
Can anyone offer any insight as to why it wouldn't? Turblown mentioned a modification to the Turbine inlet would be required but why? It's a T25 Flange.
Also, can anyone comment on the AR sizing and the power potential of this particular turbo combination?

You have that backwards the T25 Flange is the inlet for the Turbine/hot side of the turbo, the compressor/cold side has a 2.75" intake, modifying or making a new section of piping to adapt it to the rest of the Greddy piping is the least of my worries, I'm more concerned with whether or not the turbo will physically fit in the Greddy location and also if the housing sizes will offer good spool characteristics and about a 325-350rwhp capability

I think that compressor is a little better than the stock greddy but will still be too small .
The ideal compressor wheel for the renesis for anything below 350whp is the 60-1 wheel (59mm inducer/76mm exducer) used in the BNR upgrade . The fact that nobody has made that power is more to do with the lack of understanding of the issues (or the unwillingness to deal with them) than anything else.

Oh, and next time try to search because there's no point in this thread that couldn't have been better served by bumping the one that already exists:
https://www.rx8club.com/series-i-major-horsepower-upgrades-93/question-about-mm-greddy-turbo-upgrade-162615/
he basically welded a spacer to the turbine housing, the compressor housing will be too close or hit the Greddy exhaust manifold otherwise as he also put an insulation shield between the manifold and turbo. You can see it more clearly here:

not sure if there is enough room for this external WG housing?

There's a lot of great stuff in that thread on the S2K board still going over everything there.
I saw that External Wastegate housing on ATP Turbo but kind of just wrote it off as I didn't think there was anywhere close to enough room to mount a External WG in that position. It looks pretty close though, possibly with a low profile wastegate, but without actually mounting it up who knows.
