All the numbers and maps you want should be on Garrett's website. They aren't cheap!

Basically, the GT2871r's max at 750rwhp, GT3071r's max at 850rwhp and the gt35r maxed at 1038rwhp.

So, how not cheap is not cheap, lol? Ballpark? Didn't see any prices listed on Garrett's site and don't know who distributes them?

Do the gt3071r's mate right up to the incon manifolds? How much are they exactly? I'm guessing $1,200 per turbo ballpark....?

They should mate up with the flange.

It's been a while since I looked into them, but last time I checked they were a little north of this number. I want to say around $1350 ea. Check the web, I'm feeling lazy.

Something to keep in mind (or check), I believe these are water cooled from what I remember.

Flowmaster is a great y merge....be curious to see if it's worth any power.
That looks great.
What size pipe do you have coming out of your turbos? Was the flowmaster y a big difference on fit from the one you had before?

Right off the turbo flange it is 3.00, then it necks down to 2.50 in each pipe going to the Flowmaster y. The Flowmaster y has two 2.50 inlets and a 3.50 outlet (which is why it is soooo much better than the Borla y...Borla crams two 2.50 pipes into an odd shape and necks the outlet down to 2.60 inches....3.50 merge in the Flowmaster vs 2.60 in the borla...) The end of the Flowmaster necks down to 3.0 to fit a 3.0 catback.

If they are watercooled and are available with an internal gate, they'll work perfectly.

They are watercooled, have an internal gate and are "supposed" to bolt on.

Those are all ball-bearing units right? Could you get something cheaper with a conventional bearing??

Are all of the Incon style turbos watercooled? How do you plumb the two turbos with water - and keep it flowing?

However quick question concerning the exhaust setup here because my kit didn't come with the original incon Y-pipe. I would like to keep as much ground clearance as I can but don't want to hinder the turbos by going too small. Does anyone think that I would gain much going with three inch pipes to a collector into my hooker cat-back? Now I know that the hooker cat-back isn't the most turbo friend so I will be running dual QTP cutouts right after the turbos or just behind the front seats. So since I will be running dual cutouts does it matter much if they are 2.5 or a full 3 inch cutouts and pipes?

I may just try duplicating the Y-pipe setup of TTSSZ and run it into my hooker cat-back.

And has anyone ever run a hooker cat-back on an incon kit or other turbo just so I can get an idea of the performance lose.
I went though the same questions on the y before I did my set-up. The Incon y starts out at 3.00 at the turbo and necks down quickly to 2.50" (about 6 inches). At 625rwhp stock GM cats cost ~ 35 rwhp on an Incon TT. So IMHO the gains from a catless 2.50 y to a catless 3.00 y would be close to zero....a lot more clearance issues with a 3.00 y also with the Incons.
