Garrett Gt2860 -9s

[levinboy]

10 psi!!!! Jesus.

For sure will be looking at new dumps in the future. But I wish to enjoy the new found power. Besides it keeps me interested in the car if there is always something to do.

Are you running mafless?

I'm running twin Z32s with stock airbox

Haha don't worry you will find plenty to do to the car if you really look

[Hadouken]

Ah excellent.

Hmmm... As in my 4x4 status?! Lol

Just read all 13 pages, not to much mention of the -9's though they seem to have a totally diffrent opinion on -5's.

Main jist here seems to be -7 or -9 with stock motor, -5's for a storked engine.

Yet they are claiming to be making boost by 2000RPM and on song by 4k. Non stroked motors.

a few posts from a couple boys here aswell

Also don't forget that thread is quite old for the most part (2008 etc). There won't be a lot of talk of -9s as they didn't come onto the market until ~2008/2009 IIRC as they were still under the HKS GT-SS banner and expensive, and then Garrett released them etc.

I mean claims in that thread that -5s are "really into it" by 3000rpm are just plain silly. That same user then posted a graph - 4000rpm not even 170rwkw ... lol... really if that's "into it", i'd be worried.

Yes they might be building boost - but in 4th gear it'll still takes you longer from 3000rpm-4000rpm than it does from 4000rpm-8000rpm on a 2.6ltr, once the turbos are well into their sweet spot and the motor is working.

End of the day it comes down to ones 'definition' of what is/is not laggy. Turbos that come on @ 4000rpm-8000rpm for ~370rwkw or turbos that come on @ 3300rpm-7500rpm for ~330rwkw

Basically the same power band - just totally different delivery & RPM use. Then there is also response onto boost in/out of gears, on/off throttle etc.

End of the day - do what we've told you. Jump in the passenger seat and see for yourself and what you prefer.

Ok, Sifted through the rb26 turbo upgrade thread,

Looked at all -5 and -9 setups with similar mods ect

-9/hks gtss

3k rpm= 130kw

5krmp= 254

100km/ph= 16kw

110km/pk= 130kw

-5/2530

3krpm= 85 kw

3krpm= 100kw

3390rpm=80kw

5400rpm= 200kw

100km/ph=100

100km/ph=110

110km/ph=140

Not many -9/gtss examples, Though

Taken a while to sift through it all, So i thought id post this up for reference to anyone else making the choice, These are all on a std 2.6 capacity

Was actually going to go against everyone's comments and get -5' this week. But this proves the -9s shit all over there bigger brothers, Unless you plan on doing ridicules speeds.

Can u checkur numbers again

[Hadouken]

Dude, are you still trying to make up your mind?

man you just need to take the plunge and go and get whatever your goal is.

Is your goal 300-350kw? -9's

is your goal 350 - 400kw? -5's

Done, go spend your money

haha you think there off? They could be... what looks odd?

wish it was that easy....the KW range is not my goal. Although it easier to strive for a particular figure. Now im more looking at the driveablilty.

All fair and well to say you have 400kw....but its not very practical to have that at 150km

Main reason for me doing this is to compare the power at the lower range. And to me it looks like the smaller set up has alot more usable power. ( if ive read then all correctly)

Smaller turbos more driveable and have more power lower in the rev range?

Who would have thought?

[Hadouken]

Isnt that the main reason why people say go for -7's -9's if your using your car on the street?!

Then if you a bigger power figure for more competitive reasons then go -5's?!

I thought all of this has been covered before

[zebra]

Yes

At least 500 times now

[sydking]

ive taken the time to post my findings for people in the same position in the future...Dont see the big deal?

All good i see what u have done now. U changed from rom to kmh

Nah thats not the problem. What is working on my nerves is, we have said countless times, if you want it power sooner ie boost sooner, then get -7's or -9's and they will yield 300 - 350kw!

If you dont car about lag and your car is not a daily and you want peak power then get -5's and once again, they will yield 400kw's.

I see no fine print in this, it looks very straight forward to me.

has anyone actually got 350kw from -7's or

9's

[R31Nismoid]

I think someone did 360rwkw, but it's never been repeated (or confirmed).

Common is 320-330rwkw realistically and what people should expect.

+1 to comments thus far. I'm kinda sick of getting PM's about the same topic & questions
