RB26DETT Huffer Upgrade

[gun-r32]

looking for advice on replacement turbo's on RB26DETT. I have 5K budgeted including labour, will this get me a decent upgrade? Im aiming for 300 rwkw and nice fat torque down low. Cheers all

HKS GT-SS or HKS GT2530 are the two main options at this price range. it will be tight to do it within your $5K budget but not impossible.

either of the two are proven performers @ 300awkw.

[ferni]

yeah i agree with the GTSS or 2530s

[600hp]

Your going to struggle to make that power with that amount spent.if you want 300awkw you will need.

power FC

at least 550cc injectors

some adjustable cam gears

GT-RS turbos

and a big fuel pump.

and then when you want more get a set of 270 tomei cams and some valve springs and more boost.

[600hp]

sorry i should have said that yes both turbo's GT-SS and 2530's can both crack big power but the GT-RS turbos will get you to that power quicker.

we've seen 367awkw with our GT-SS turbo and i know of someone who makes over 400awkw with 2530's.

GT-RS turbo's kick in like a big single,sounds mad on the dyno.

[gun-r32]

any idea the retail on GT-RS terbz?

[Gts-t]

You should check out the trust bolt on turbos, they would fit your price range better as they are only oil cooled like the standard turbos. I think a pair of the T518Z can flow 700hp. As they dont need water lines made up they are cheaper to fit.

Trust say all sorts of fancy things about the comp housings on them, about being specifically designed for the gtr for good responce and so on.

Another bonus for your budget is that you are forced to run blended(cheaper) dump pipes allowing you to perhaps spend more on some nice front pipes i dont know.

The dude from willall racing rates them or something, im really singing his song.

zzz time

Standard GTR turbines ARE water cooled.

5K will get your turbo kit including fitting, but not much else. Budget another couple of grand for and ECU and injectors at least.

In my opinion, if you are going to get 2530s, you might as well go for GTRSs...as they are much more modern, make power easier and aren't much laggier at all. I don't think 2530s are available anymore anyway.

Otherwise, if you really want low down power, get GTSSs.

Apparently, another good option are Tomei Turbines, but no one knows much about them our here.

N1s are another good option, but you have to be careful, as there are quite a few different types.

R34 N1 ball bearing turbos are definitely the better of the N1 range

[Blitz]

2530's are still available but being replaced by the 2530KAI.

GT-SS will make 300rwkw no problem, no need to go for GT-RS which are not popular for a street car anyway. GT-SS will give you an excellent and responsive package for a reasonable price.

[Mik]

Blitz...I don't think you can get the 2530KAI in T25 flange for RB26, can you?

[Ronin 09]

The way i've understood in terms of power level (as long as you have all other support systems etc) from low to high

Standard

N1s

GT-SS

2530s

GT-RS

Can anyone confirm this understanding?

the two best i have seen going aroud

R34 N1 Ball bearing

HKS 2530

both about the same size in hp

and if i was to try and spell the differences, in my opinion the R34 N1 work better at the lower boost (comes on a little quicker)1.3 to 1.5bar BUT the 2530 has more potental for high boost 1.7bar onwards

summary for every day driving is the better option and to go out and out high boost 2530, thats only in my opinion and i am happily run 530rwhp out of my 320hp garrets at 20psi

[600hp]

I've seen N1's make 350awkw

[williamsf1]

so who can spell out which R34 N1 turbos are the "gun" 320hp variety.... Im after the serial number so I can plot my way through this maze of 34 N1 turbos (last count there are 4 types!)

williamsf1 I'm taking my turbos off very soon to fit new stainless manifolds will send you the model number then

[williamsf1]

ahh ok pete! I didnt know you had R34 N1's I thought they were the garrett equivilent of the HKS 2530?

anyhow Im still searching for a set of N1s or 2530s..... hmmm

[DAN00H]

gun-r32 I'd stay away from GT-RS for a street GTR. 2530 or GT-SS is what you want.

I don't know why everyone seems to think this. The difference in lag between GT-RS turbines and 2530s is minimal.

[williamsf1]

G'day Mik, so what sort of engine did or do you have these GTRS bolted to? Im looking at just a stock motor with tomei cams bigger injectors...PFC etc...

and what revs are you getting 1 bar boost at?
