New Garrett GTX2867r

[240sxfan6882]

Still no updates on this I'm anxious too!

I'll add something to this thread too.


I have a KA24DET and Im converting to bottom mount with stock SR mani converted to KA24DE.

I ordered a GTX2867r with .82AR with the ATP T25 Plus external gate 2.5" V-band housing. It should be here next week I hope! The conversion should only take a few days at most (i hope).

Ill keep ya'll posted!



Thanks a ton to shiftdrift (a member on here) for building this up for me.

any reason you chose the .82 over the .64 w/ the t25 plus housing?

seem too large for a t28 turbo, but you have .4 liters more displacement so maybe not

Yes there is: it was almost free lol. The 82 tends to work better with the ka.. specially since I have a .5 litter more than an Sr, and port and polished heads and 9:1 compression. Move quite a bit of air. I'll let u know

[240sxfan6882]

I got mine in today! .82 T 25 Plus housing with 2.5" V-Band on a converted to KA - SR manifold. I hope to test fit it to the car next weekend I hope! It took 2 weeks for me to get it.

Cant wait to get that puppy going!

[ka-turbo]

sweet!!!!!!!! cant wait to see a fellow KA results on the same turbo...and hopefully you have results!!!!.....wth is going on with ppls results on this turbo!?!?!?!?!?!?!!?

@ cody ace.

You are the t28 frame guru so I will see what you think. I have been back and forth between many different turbos and Ill outline my goals and see what you guys think.


My current SR setup consists of:

s14
tomei 260s
VTC working
CP pistons 8.5 comp
eagle rods
acl bearings
Apexi intake manifold.
Greddy type LS intercooler
tomei expreme exhaust manifold t2 IWG
dbb t28

Im adding 820cc injectors a aero 340 lph and a cobra MAF is needed.

I have 3 turbos in my hands.

A dbb t28 from a s15
a gt2871r .64 AR t2 Internal gate
a gt3071r t2 external gate

I want to convert to a GTX t2, t3 external setup.

Im looking to try to push the gtx2867r to the limit. Im going to be spraying 50/50 water/meth

My goals are as responsive to just over 400whp. Ive looked into twinscroll hx35s twinscroll gtx3071rs and they just dont seem worth switching my setup for these. I can mod the current mani for t2 t3 or EWG thats not an issue.

Now are there any ADDITIONAL things I can do to the gtx2867r to give me slightly more top end? Im going to use a dremel on it and try to make it AS smooth as possible.


Im trying to get as much power as possible out of the t28 frame and just wondering where the limit is? I dont want to convert to a top mount setup. Like you said any top mount setup making less than 500whp is IMO a waste of time.

Alot of the non nissan community around here seems to think t28 turbos max out at 300whp. Which is perfect for me.

Cody is the master of this and hopefully can answer your question soon.
What he will probably suggest is getting the manifold extrude-honed (High Performance, High Output Racing - GetHoned) to smooth out the air flow in the manifold and increase the volume slightly for more CFM. I was considering doing that to the manifold but its $500!!!
The reason I wanted a stock SR manifold is because of the strength of it, the fact that you can attach a stock heat shield to it, and the pulse pairing. But... with an external WG setup like I did mine the pairing is pretty much destroyed.
Ill be mounting mine soon, just ironing out some minor stuff on my KA

Just adding my info for others.
My set up is
s15 motor
GTX2867 .63ar internal gate
JWT s3 cams
Greddy intake mani, (stock small ass TB)
Tomei EX mani
Moonface full down pipe, 3in ex with cat
Haltech PNP
removed stock fan
stock head gasket and studs.
E85 17-falling to 15 psi
looking to turn up the wick in a few weeks.

[unijabnx2000]

You should of gotten the .86 ar housing IMO

[eflove]

Not worth it IMO.

[240sxfan6882]

eflove: Nice power for being at only 17-15psi. So your falling to 15psi at around 6k rpm? It starts to pull like a mother at 2.5kRPM! Im about to start converting mine sometime next month

this, this is like

[hoggie]

very nice power!!

i have tomei arms 7960 turbo kit on my red top SR

my engine is stock,

it made 347whp 372whtq at 16.5-17psi on a dyno dynamics

just tossing it out there for comparison for people shopping around.

S13 SILVIA CONVERTIBLE SR20DET TOMEI ARMS 7960 - YouTube

[e1_griego]

Here's my gtx2867 .64 dyno:



Redtop s13
Stock hg, stock pistons
HKS 264 Step 1
Power FC L-jet
Tomei 740s
codyace modded stock ex. manifold with Tial MVR
stock intake manifold
PBM cobra dp
15psi

This mustang dyno generally doesn't read as high as the dynojet I had my car on before (where it did 340/300 on a gt2876 @14ish psi).

I much much much prefer this turbo. What the dyno doesn't show is that this turbo makes some boost every time you put your foot down. Full boost is still ~3800, but some boost all the time. It gets going much quicker than my gt2876, that's for sure.

240sxfan-It feel like a 400hp car bc of the TQ everwhere. I just drop the car off with my tuner. I don't have the data logs so I'm not sure when it's dropping.

Z33dori- thanks man. I spent a little extra time and had everything powder coated this time.

[steve shadows]

Sick, Sexy Turbo. End of Story. I got to talk to a lead Garrett tech about it for a few hours again recently too. Garrett is still the ish guys. Good/Great stuff!

Excellent! And you even used a real dyno! haha Dyno Dynamics!

Great numbers. Exactly where you should be. PS what octane were you running?

I am still getting people around 300 WHP (with the regular old 2871R .64 housing) on Dyno Dynamics on 91 octane out here in shit gas country I am sure you have some better options which really helped up there as well. Thanks

I live in Toronto, Ontario, Canada, highest octane we have available here is 94.

that's probably the 20-30whp difference from octane ratings..lol

do you have a ignition system? like MSD, Splitfire, circuit sport dis

i got the circuit sport DIS sparks were so much better it probably made 10whp from that mod alone, and its cheap price wise compared to others...made for SR20DETs specifically too, should get one if you dont have one!

I tune other peoples cars mostly now, by request or personal appointment when it comes up. But from my experience the octane difference does help a lot. Especially 94. But I think even with 94 we couldn't have gotten those numbers on that dyno down here with a reg ole' 2871R. Cheers to Garrett at the end of the day...oh and cheers to your tuner/you did a great job nice graph!

Oh and on the ignition thing. I typically consult people to just stick with stock. Unless you're up over 400 whp you're not really going to have real blow out issues if the plugs and grounds and everything is working right. If you just want better spark then there are some minor benefits but usually don't see more than 10-15 HP on the smaller turbo hp setups.

Just as an example for my last 240, we did over 450 WHP on the dyno dynamics with a gt3076R on 19 psi with 91-100 mix. Mostly 91 though. That was with stock ignition, stock fpr, STOCK PISTONS AND RODS, stock fuel rail modded for the greddy IM. The Q45 TB helps a lot though. Greatest upgrade you can do for the money for response with any turbo. When that thing is barley taped you're sucking in as much air as a stock TB and they are practically bullet proof and almost never break if the cable is anywhere near rigged up right. I would love to see what we could do with the new GTX3076R too...

[hoggie]

^ nice! i'll have to look into the Q45 TB for my car...haha

i got the OEM intake manifold for my red top SR20, would this be bolt on or adaptors would be needed? or if it even fits at all?

im just superise to see that my tq is more than the hp...because its different from most charts i see on this thread....im not a tuner, so i wont know why it came out that way...but the tomei kit is made by garret...just a beefed up version of the 2871r. would you mind explaining why?

[BlackZenkiS14]

So is anyone running one of the gtx2867r's in a bolt-on setup with internal gate on stock manifold, and stock style turbo outlet?

I pretty much just want to replace my s15 turbo with one of the new ones and not have to change a Bunch of other parts in the process. I'll do some s3 cams eventually. I'm trying to decide which would be more effective to get first, cams or this new turbo.

My current setup is 740cc nismo injectors, z32 maf, jwt tune, Greddy intake man, and 50/50 watermeth injection on a 7gph nozzle. I just want to add this new garret turbo to this setup, and make 350whp, how possible does that sound?

Horsepower is a made up number based off of torque. It can be caused by many things in your case it looks like a slight overboost as you hit your target pressure caused a increase in power. HP is a function of torque and rpm.

[eflove]

Just a heads up if you want a bolt in turbo you'll have to order from atp. garret doesnt offer the 2 bolt in 3 bolt out style cover but atp does. They bore them out to fit the GTX family.

[JFoxx]

not real impressed with the #'s i was making better # with my hks gtrs and ive had that for years.......

[usdm180sx]

^Good to see. The gt-rs is the only turbo upgrade I've done for both of my 240's =) Can't deny the spool up, power and fun!

That's what I was figuring. I don't mind ATP, a lil pricey, but good shop

[huffandpuff00]

new ATP t25 plus .63 housing all welded up. Should be a considerable amount more of clearance for the WG given how low this flange is placed compared to my other ATP .72 housing. Also Alex from PSI, being the amazing welder he is, welded the inside of the flange to insure the weight of the WG wouldn't cause any problems down the road. Still deciding if i want to go 2863 or 67...

[huffandpuff00]

@240sxfan6882
I don't know if you saw that atp makes a flange that fits on the t25 plus housing and excepts 3" exhaust pipe. Because we are still bottom mount i know theres not to much room between the turbo and firewall, so if the 2.5 to 3" flange adapter doesn't work out, check these out.
