garrett GT3071r (WG) good upgrade for greddy turbo kit??

You can get a T04e compressor housing with a 2.75" turbo inlet that will fit on the manifold. I have one and it fit on the manifold fine, the problem I had was fabricating a oil drain.

Driving my unreliable rx8
I went with a piece of 3/4 copper tubing 5/8 id. -10 fitting on the turbo and the oil pan drain.

In another thread I posted this link in Brettus 11 thread
FC3S Pro v2.0:  Turbo Tech - Compressor Maps
Looked a bit further:
Turbo Compressor Chart
But I'm struggling to understand it. I was wondering if the "Super V- trim" would be more laggy than the 57 trim? Compressor wheel has smaller diameter, as far as I can see, but same average(60-1 is larger, means more laggy I presume). At the turbine(hot) side, it say "see below", and I do not understand how to interpret it. Could someone assist/explain?

The map that is commonly associated with it seems to actually be the wrong map . The 57 trim is actually very close to the 60 trim that they rave about in that article and in practice performs better than they suggest. I really doubt the 60 trim is capable of 400whp as they suggest though as you need around 60lbs/min for that.
The other problem with the boxes that they display in that article is that a 13b will flow a lot more air (at higher rpm and PR) than they show there . Past 7000 the Renesis will flow around 53lbs/min at a PR of 2.0 .

So if you were looking to hit that 310-320 WHP range would you recommend the To4e 57 or 60? I know I've read in other threads that it is pointless to run the 60-1 unless you plan to push high boost (15+ psi) and attempt over 350whp....

Seems like you have stepped into a wormhole of questions here Brettus
I really appreciate that you bother explaining, thanks.
In the map, you have marked points, and at 15PSI you have written 10PSI at UIM. I read this as you have a pressure drop of 15-10=5 PSI over IC? And this pressure drop makes the turbo perform better, and therefore barely are supporting our Aux ports. So if running 10-12PSI, then you should have second thoughts fitting "mother of all IC" in your setup.
So I'm wondering the same as RotaryMachine, would a 60trim be better maybe? Or would the drawbacks be bigger than the advantage for a 310-320WHP goal.
Another thing I notice, is that surge line at the 20G seems slightly more forgiving than 57trim, is that to any advantage for us? Making 20G might be the best option?

What the map shows quite well is that the 20g,57 and even the 60 trim wheels are a little small to have the Aux ports left open. If you were to transpose the stock Greddy on there you would see that leaving the Aux ports open with that turbo is pure folly.
The power figures quoted on the map are a litttle inflated.I should redo it .

Well, 2.5 is almost a 5% increase. This means you can go from 315 to 330+whp, with the same margins. Or 400RPM extra at the same torque. Maybe what we will be looking for to keep rev range high and APV open?

Oh, I thought you meant it was a wheel you could upgrade to with the Greddy the same as the 57 or 60 trim...... I've still got alot of homework to do and not enough time to do it at the moment haha

I just went back and checked my emails for the specs on mine when I had it rebuilt.
• Water & Oil Cooled CHRA
• BIG TD06H Turbine Shaft
• 54 Trim 44lb/min Billet aluminum compressor wheel from Comp Turbo
• New Bearings
• New Seals
• Machined Compressor Housing
• Machined Turbine Housing
• Balanced
She will be back in boost next weekend and at the tuner soon after so we shall see how it goes.
