New Garrett GTX2867r

[boostfreak27]

So it is time to replace the turbo on my Sr. as the seals are going out and leaking oil. The gt2871r was my original and simple choice. After hearing about Garrets new expanded line of their gtx turbos I decided to stretch my budget and see how these perform on the sr. So I ordered the Gtx 2867r and am setting it up for an external wastegate. Turbo came in yesterday, and i still have a few loose ends that i need to finish before getting the car on a dyno for a tune. I haven’t seen anyone run one of these on an Sr yet so I’m excited to see how it does. Just thought id give everyone a heads up , and hopefully we will have some dyno graphs to check out soon!

[brndck]

please give details, dyno graphs, etc,
before and after?
these are still single scroll, no? pix of exhaust side?

[AdrenalineS14]

Mmmmmmm I def wanna know the results! Def interested in how this turbo performs!

[Croustibat]

Very interested too. A friend of mine is going to fit it on its CA, and i might as well next time i blow a turbo.

[Seraphim38]

Yup I am curious as well, though I have a 2871R .64 with less than a thousand miles on it that I will be updating with the T25-EWG-44 .72 housing, which means I won't be buying the OP's discussed turbo any time soon...

[didderson]

Keep us in the know man!

[boostfreak27]

Yes, the turbo is still single scroll. I never had the car on a dyno before, but im sure there are plentyof base line dynos you can compare to.
Engine mods are:
CP pistons
H- beam rods
Comtech hg
Arp head studs and main bolts
Bc valve spring and retainers
C/S ras
Tomei 260 cams
Megan exhaust mani
Front mount
Nismo 740 cc inj
Greddy ProfecII boost controller
Aem Fic

Looking foreward to getting this thing done. Ill post a pic of the turbine housing soon.

[!Zar!]

I must say this is indeed interesting.

[Walperstyle]

This effieiency of these turbos is amazing. Way less chance of compressor surge. I wish I would have purchased one of these, but they are expensive.

Hi,
Although I dont own any of the cars on this site, or even a car with a SR engine. I've been watching this thread. I'm placing my order for the gtx2867r this thursday. I was told it has a anti-surge housing but its hard to tell in your pics. Can you verify this?

Looking forward to dyno results.

What are you getting the turbo for?

I have a built zx2 with the zetec powerplant. Engine is fully built, coated internals, cnc'd head with a hand pnp, OS valves, arp throughout, aftermarket block, aftermarket mains, coated acl bearings, 3 stage dry sump with a peterson tank, aftermarket intake mani, crown vic tb, 2.5" ic piping, hargett clamps, full mandrel bent 304SS exhaust w/v-band clamps throughout. Megasquirt for tuning.

Just recently (a week ago) sold my gt2860rs, had a tial v-band housing laying around so I'm doing that with this turbo. I've yet to order. Pulled the engine last sat to do a few other mods to it..and found oil in the exhaust port of cylinder 3. I've yet to investigate it but I think its the valve stem seals. Not to worried about it.

You should get a 240

^ford escort? Pending your fuel choice and tune, you could get 400hp+ with this turbo, and the housing makes it way better to avoid surge. If you go to Garrett's website you can see graphs of how this stacks up with the regular turbo's, as well as go through the 'turbo selection app' to figure out approx what turbo best fits your car.

You should also consider sticking with hot side no larger then .70 ar. It all depends on what your goals are, but 4 cylinder engines want smaller exhaust housings.

I had great luck with the .86 hotside. Someone with the same gt2860rs made 360whp on 21psi. The new gtx3076r another guy made 602whp on alittle over 30psi.

Currently I'm running 93 but will be swapping to e85 after this turbo. My goal isn't so much as overall whp but because I have a dry sump I can rev incredibly high. A gtx series should suit me fine for higher rpm's.

Escort/zx2 whatever you want to call it.

What is the displacement of the engine? I have a .82 hotside on a GT35R turbo and I've calculated that not much is going to happen till way later in the RPM range. .64 makes for faster spool.

You have a dyno graph, I always like to see.

stock displacement is 1998, I should be a hair over that with the bore.

On the gt2860rs with .86 a/r I was hitting 1 bar around 3100rpm's. This isn't from watching gauges. This is what datalogs tell me.

The gt35r never worked real well for the zetec.

Yes it is an anti surge housing. Sorry for the glare. Ill upload a few mor pics of my progress and turbo tomorrow. Thanks

Awesome can't wait to see.

That's because AR isn't the same for different Turbo groups. A .86 AR on a 35 is much larger than a. 86 on a 28.

[boostfreak27]

Okay so time for a little update. Got the turbo mocked up. Everything fit together quite well and looks great. I'm still waiting for my wastegate to arrive, i have a little over 4" to the strut tower. The new Tial vmr wastegate is a little smaller than their previous version so hopefully everything fits! Next step is to install the wastegate and weld up a new 3" intake and dump tube at my shop.

[Walperstyle]

sweetness sweet

[boostfreak27]

Sorry about that, should be good now.

[EsChassisLove]

How much was this?

I have a fresh 2871 on my SR and I am rebuilding right now. I might sell the 2871 and get this bad boy.

[Seraphim38]

Finally some pics! and not only that, pics include the housing that enables external wastegate mounting! I have been considering converting over to the T25-EWG-44 housing on my current 2871R but so little info exists from actual users.

By the way, ATP sells a v-band 90 degree bend elbow so that you can mount a standard 44mm Tial v-band at whatever angle you want. It's much more convenient than trying to fit the wastegate directly on the housing. $69

44mm is hella overkill for that little turbo. lol

[Freddy]

oh please provide dyno charts

please

I had no issues with the gt2860rs and the tial 44v. Considering this turbo is good for nearly 40psi, I say a 44mm wastegate is fine.

[Bubba]

I am very interested to see what you do with this turbo on the SR20 since I have been looking at the GTX3071 and 3076 setups for my KA-t.

I'm not shooting for high numbers as much as I am shooting for response time.

Can't wait to see a dyno graph.

[jr_ss]

This looks promising... I'm currently building a VVL setup with a GTX3076R w/ a .82 hotside.
