Garrett Gt2860 -9s

[levinboy]

Huge cams for that turbo and engine setup!

Cams are working quiet nicely on this set up and sound awesome

330rwkw @ 16psi up top & then drops to 300rwkw @ 20psi up top on the 2nd graph (4psi more, 30rwkw less!) - If nothing else was changed that is very interesting!

Not 100% sure if anything else was changed, i know i dont have to rev past 7 the way it is set up at the moment

Will be going in for more fine tuning before nationals as this was done just before WTAC

all in all very happy with the car

Just read the whole thread, all 14 pages. Good read, it helped me realize that 9's is what I should be running due to using my r33 GTR as a daily and not yet chasing insane power figures.

That said, I think I remember reading g that 9's do not come with actuators? What ones do you guys reccomend and why?

[Moodles2]

There are 2 types of -9's, 707160-9 without actuators, 780371-1 with actuators. You can buy adjustable garrett actuators from GCG that are cheaper than HKS adjustables.

great thread , helped me a lot in choosing turbos

i am about to buy pair of this ones : GT2860R - 739548-9

are these those super responsive 9s you guys are talking here?

it has 64 rear and 60 front and stated that its bolt on for rb26 .

is there any major difference between 739548-9 and 707160-9

turbo part number gurus help would be great

thx

[wedge_r34gtr]

739548-9 are not bolt on for a rb26. They have a different exhaust flange.

Part number tells you what is bolt on, and what is not - almost impossible to get it wrong.

[avoiee]

it is bolt on , this is what it says : Turbine wheel is cast from "Inconel" material for extreme applications, Essentially a GT2860RS Disco Potato turbo with a GT2560R compressor housing , Upgrade turbocharger for GT2554R (PN 471171-3) and GT2854R (PN 471171-9)

430609-230 0.64 Wastegated T25 5-Bolt - rear housing

i am just all confused with all this part numbers, just wanna know if these are 9s that this thread is about? or this ones are more like 5s or 7s?

thx

[wedge_r34gtr]

sorry should have been more specific.

The part number you quoted first is the '2860-9' turbo with the SR20 style flange, BUT this turbo with with the option 430609-230 exhaust housing is what your after (i.e. the -9 of this thread). The correct turbo part numbers for the rb26 are a few posts above.

Ok these are specs after search on garret

739548-9 446179-66 47.20 60.10 62 0.60 53.90 76 0.64

707160-5 446179-51 47.20 60.10 62 0.60 53.90 76 0.64

707160-9 446179-65 44.50 59.40 56 0.42 53.90 62 0.64

So i am looking on more like 5s right? just shra's have different part numbers rest is same . shit already purchased them so i got lugy big turbos for my stock engine

when i saw 9 at the end i thought thats the ones i need

wedge_r34gtr

what you are saying is that these are 2860-9s for sr20 but with different exhaust to suit rb26 its still the ones i was looking for?

could you plz take a look numbers above and would you still thing that those are 9s for rb26 ?

sorry for my english as well

[wedge_r34gtr]

mmm... my garatt catalogue has the wrong part number for -9's.

The 707160-9 is what you were after. Email the shop and make sure thats what your getting. I don't think these come with actuators either...

[Serpandrew]

Just had a full read of this also, made my choice and i'm dead set on it now. -9's it is.

As for the actuators i'll have to decide on that when the time comes

Good choice

[Serpandrew]

This thread should be pinned and name changed to "Garrett turbos for RB26's -5 vs -7 vs -9" or something.

Probably would be really useful to most GTR owners looking for advice and results on which turbos to go for. All of this is great info is in one spot (Aside from the RB26 turbo upgrade results thread).

Heck i'd been trying to decide for a while reading a million different posts and sources on other websites, this thread educated me and made my decision.

Hey guys,

Just went on nengun and it reads that HKS have changed the compressor wheel, compressor housing and turbo housing. Not sure if its fibs or not?! Can anyone confirm this?

Cheers

No reason to think they fibbing, they are aftermarket turbos after all. Wouldn't be too popular if they had the same specs as stockers.

You are not doing english correctly. All that says is this:

Compared to stock turbos, they are larger.

It is NOT SAYING that "GT-SS" are magically bigger than "Garrett -9s", which share the same part number.

[M34N-R]

Not doing English correctly?! At no point did I mention that they are magically bigger. I am basically only asking whether this sentence:

The clearance and shape of the compressor wheel, compressor housing and turbo housing are redesigned to optimum specs.

Means that HKS have done more then just put their actuators on garrett -9s?

[Moodles2]

This may not be 100% accurate but it's close enough: HKS used the -7 and redesigned the compressor wheel and tweaked other small things and called them GT-SS. Garrett made these turbos for HKS (with HKS stamped compressor covers) without actuators (because HKS fitted their own adjustable actuators) for 5 years until the deal between them expired which allowed Garrett to sell that turbo to the public which they called the 707160-9 (or -9 for short). For acouple years now, HKS GT-SS kits have been coming with Garrett stamped compressor covers. Difference between the HKS and Garrett stamped cover in the GT-SS kits? Nothing, just the old kits have HKS covers, and new ones have Garrett covers.

[Hadouken]

And we can clearly see the mark up due to having a big jap name on something.

Mr meanR you however have to cap your anger, this is a internet forum and we are not mind readers. If you want something then you have to be detailed and precise. So just go and buy the pretty hks units oh I mean garrett.

[M34N-R]

Cheers Lance, so just to confirm, do the GTSS's still carry different internal specs over the -9s? I understand there the same size and the compressor covers are the same stamped regardless. Cheers mate

Hadouken, at not point did I get angry, my apologies if you think otherwise. Was just replying to a response.
