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.

 

Wow, that was a great help. Thanks man!

Could you be a little more specific about the "throttle body coolant bypass mod"?

 

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!

 

I thought the 2871 RS was the one to get, not the 2871 R, since the RS flows a lot more?

 

Everytime I read about the upgrade it's always the GT2871R. This is the 1st time I hear of the "RS" version.

 

Where did you get the idea that the "Disco Potato" flows more?

Read the flow maps:






FAIL!

 

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.

 

You didn't get the right turbo.
The 2871R is exactly the same size and shape as the TD06-18G.

 

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....

 

That is an EXCELENT idea. I would be 1st in line!!!

 

Really? I am pretty sure that I got a genuine 2871r. Wish I still had it so that I could compare it.

 

Working on it.

 

good, cause my turbo is starting to smoke at stop lights, and I had the oil restrictor in place

 

SWEET!!!!

Do you have an idea when the kit might be ready? Ball park?

I will place an order for the interceptor-x at the same time.

 

No ETA. Probably before Spring.

 

sorry - could not help myself ....

 

Heat/carbon damage to the journal bearings.

How long do you idle down before you shut off the car?

BTW - New bearings are only about $10 and are real easy to install (once you get the turbo out of the car).

 

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.

 

dyno sheet by tomorrow or it didn't happen

 

Well, it hasn't happened yet anyways! I am still waiting on some parts, mainly the turbo. It won't happen until November or even December.

 

Or January or February...

I'm still in the middle of a bunch of other junk, Dave. I'm leaving for SEMA tonight, so I'll give you a call when I'm heading north and try to swing by your way.

 

I don't idle very long. But I stay out of boost the last 5 minutes of my trip before I park the car.

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.
