Anyone upgrade the turbo on Greddy kit yet?
I need to get my car dyno tuned very soon but I was thinking to upgrade to the GT2871R turbo at the same time.
I know that I need a fuel pump and injectors but what else do I need?

you need to get the 2871r configured right- GT 5-bolt discharge housing with built-in internal wastegate, T25 inlet housing, 0.86 A/R turbine housing, and a 0.60 A/R compressor housing.
New P2 fuel injectors and fuel pump like you mentioned
The air intake pipe will need to be modified to slip onto the inlet of the 2871r.
The new Garrett turbo is also water cooled, so you will need to run coolant lines to it. The easiest way is to do a throttle body coolant bypass mod and use those coolant hoses.

look it up in the DIY section.
Basically, there is coolant flowing through our throttle bodies. You can disconnect the two 3/8" coolant hoses that connect to either side of the throttle body and the connect them to one another, thus bypassing the throttle body, so you don't preheat your intake air with hot coolant. Instead of connecting them to one another tho, you can extend them with two 3/8" brass barbs and route them to the turbo for the coolant hoses. You will need some extra 3/8" emission hose.
However, if you live in a place of the world where it gots cold, I wouldn't recommend bypassing your throttle body. If you do, there is a chance the throttle plate can get stuck in cold weather.
Just noticed you live in Canada, so I would advise against the throttle body bypass mod. You will need to tap into something for your coolant lines. You could put two brass T-fittings on the throttle body hoses, one for feed and one for return.

Makes perfect sense.
I do plan to drive my car thru the winter so I agree that its best if I just tap into the coolant lines.
Thanks for your help bro!

Just to add to what CW mentioned:
You will also have to "clock" the turbo and move the wastegate actuator.
Not a big deal, but it may require a new bracket.
If you are comfortable fabbing the new discharge pipe, the WG actuator bracket will be a piece of cake.
I just made one for my new actuator on the old turbo this afternoon. It took about 10 - 15 minutes.

Even with clocking and moving the wastegate actuator it still will not fit onto the Greddy manifold without contacting it and will not sit flush. You would have to fab some type of flange adapter or spacer to make it fit flush and clear the manifold. I tried but lost interest and sold both my turbo and kit.

MM, you should sell the correct turbo with the proper modifications so that people who want to upgrade have an upgrade path.. cause it seems no one else out there knows how to do it, or is willing to sell such an upgrade.
Just a thought....

Folks, I'm going to have a 2871R put in my car with the help of Jeff (MM) and myself, and there will be a full write-up about it posted up with pictures. We will have detailed pictures showing would what needs to be modified and how you install the new turbo. Just be patient, it won't be until late November probably.

I've been using this turbo for 13k miles btw. And the smoking doesn't happen all the time. Randomly it does it.... maybe 5x so far, but it's a lot of smoke.
