Garrett Gt2860 -9s

Doesnt boost automatically raise when cam timing is changed via gears??

If so i think we're only seeing part of the picture as we cannot attribute those gains seen "just" as a change in cam timing but also an increase in boost

Would have loved to see a boost plot on this graph too

peak boost wasn't changed. 15psi before and after. i've posted the power v boost graph before I'm sure. someone better than me at searching could probably find it. as the man said, it may bring boost on earlier so it hits peak sooner but it didn't change what that peak was.

I wasn't running stock actuators. I was running HKS actuators and a profec B II and peak boost didn't change. only thing changed was the cam timing. the EBC kept the boost where it was.

ok quick update on mine if ppl were curious...

front pipes (big fat mofos) are in

aftermarket cat is in... its a justjap item (it hasnt been bashed out)

3.5" exhaust in

the car still has its original tune so there is not much difference in lag.... i think there seems to be less lag in on/off throttle response

gonna wait till i get all the other stuff (cam gears, injectors, afms etc) before retuning

new exhaust will def provide more power tho... straight after the exhaust was done the car started backfiring and misfiring at high rpms

time will tell

Any body know if this turbo and the 780371 - 1 (same unit but with actuator) is available from garrett now??

The supplier here say they are on back order

???

Some place on ebay is selling dash 9's WITH actuactors for 2250 total delivered, pretty cheap.

Or if you are really keen they can be purchased from the U.S for a good price with the dollar nice and strong, only issue doing this way would be shipping costs.

Note: These turbos are more commonly called GT2859 rather than the GT2860-9, so try that when searching for suppliers.

Pretty sure there is an RB26 dyno thread sticky with all of this information in it.

PM 6boost.com, Matt's pricing is pretty sharp and a local supplier/support.

Not in Aus

Not in US

Just want to know if the distributor here is giving me BS as they claim they deal directly with Garrett

Getting mine through 6boost pricing is very good and really good to deal with!!! Just FYI stocks are low of the -9s in Australia so you will be looking at a 3month wait if not instock!!!

Lucky mine are in the mail

[J'z-R33]

Hmm.. better confirm my order..

[J - Rad]

I think you're nearly better off buying the HKS GT-SS kit. Comes with all gaskets and studs, so when you add the price of turbos + actuators + gaskets/studs the HKS kit is pretty on the money for a better item

With the price I paid I got everything including gaskets for alot less then the GTSS kit which is the exact same turbo just with HKS stamped on it, but each to their own I guess I'm happy with my purchase!!!

[usmair]

i think I paid $980 each for mine... had a friend who got me a good deal

[Don Dada]

Well since there is NO info on this here I just thought i'd put this up and update as I go along.

The comparision below is results for the -1 turbo which is the -9 that comes with a 8.8psi actuator from Garrett, compared to stock R33 Gtr turbos.

The top window is the -1/-9 which reaches the same level of boost(13.3psi) about 200-300rpm later than the stocks, and the car drives basically the same as before.

The ONLY thing changed was the boost level was raised only one notch on the controller (profecb2) to get the same level for comparision....start/gain etc was left the same and the pfc tune was untouched.

My boost control kit reads 1psi low for some reason, hence 13.3psi

Ignore the scale on the bottom as this would be different due to the length(secs) of each log

[dori34]

when are you gonna put it on the dyno don dada ?

[smithy85]

Good job Don Dada, always good to see the actual evidence.

I am in the same boat at the moment.

My car made 233kw with the standard turbos, full exhaust, power fc, cam gears and profec2. I have just installed -9's last week and have been driving the car to work and notice that these turbos come on a bit later -200/300rpm later, although this is on the same tune. The car pulls a touch harder but really don't want to rev it hard at all, so without a tune it is hard to compare turbos.

I do think there is massive potential to be had just from the tune + cam gear setup and believe these turbos can give boost response as good as stock. The car was previously tuned by JEM and will be back in there next week for the new tune in which I want to get as much mid range as possible, because I am not overly interested in revving the ring out of the engine just to pull an extra 10kw and blow it to pieces.

I will have definite results and comparisons at the end of next week. Should be interesting.

[SiR_RB]

Your never gonna run more power with bigger then stock turbos and expect stock turbo response.

-9/-7 are gun choice for "near" stock response

[N1GTR]

Good on you Don Dada for trying something new.

Always wondered how the other "dash" turbos would go against the 4 common choices

[smithy85]

Well 'seat of the pants' the old turbos pulled hard at 3500-3700 @14.5 psi, so the newer -9s don't have much to beat especially if setup purely for boost response and mid range torque, rather than peak power. We'll see.

[Don Dada]

when are you gonna put it on the dyno don dada ?

Dyno tune will be a while still when I'm ready to adjust the cam gears.Until then its road tuned

N1GTR.. Technically the only thing new about this is the actuators, and I'm sure if you purchaced -9 from gcg etc. they would put on the same 8.8psi actuator like what I got. Otherwise, same -1 / -9 / Gtss unit.

I think response can be tweaked further with the tune and also with boost control as there is no creep and very minimal spike(1psi) as is right now, so definately some gain to be have there, even if minimal.....and then there are cam gears

Have only been driving it a few days, but it does pull a touch harder on 13psi, But so far I'm satisfied that I have turbs capable of 300rwkw with stock like response.
