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

The add doesnt mention -9s - that's something you've read into it. You appear to have assumed the HKS statements are in comparison to -9s, which is not correct.

do the GTSS's still carry different internal specs over the -9s?

No. They come out the same factory(s) (Garrett's factories around the world, my -9's came from their Mexico factory etc), it wouldn't make sense if Garrett built the entire complete turbo to HKS' specs (minus actuator), and then for HKS to just go and open them up and change it again.

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.

Yes you did, you copied the ad - which is comparing GT-SS to factory turbos. NOT to Garrett -9s

HKS and Garrett items are identical.

I didnt know garrett made the turbo to HKS SPECS, i asumed that HKS got the turbo's from garrett and from that sentence i posted earlier... I misconstrued to be HKS putting their own internals in. (Just like -5s to 2530s)

Anyone that says GT-SS & -9s are different, is full of shit.

The only difference is the actuator - HKS supply it with the kit. With Garrett you need to order.

GT-SS were under licence from Garrett for a few years, and thus -9s only came onto the market by Garrett around 3-4 years ago where previously you could ONLY by then from HKS - with the ridiculous mark up.

2530s and -5s however there IS a difference in the wheels, and this is signified by the different CHRA numbers and ID tags.

Hks Gtss CHRA = 446179-65

Garrett -9 CHRA =446179-65

Same CHRA number means same ball bearing center WITH same size/spec wheels attached, and as we already know the comp and turbine housings have the same A/R between the two.....

Sooo.....Go have a beer, and reminisce on the good ole days :yes:

Out of interest I was told by a turbo whore friend who used to have a bedroom full of car parts that the HKS turbo use a steel ball bearing cage where as the Garret are plastic. Any truth to it or maybe that was one of the things that differentiated the 2530 and -5s

Ok thank you GOJIR4, I just saw the GT2860 and thought I was in the right place.

Yes I'm aware that the turbo is not a bolt on, the reason for my queston was because the factory air intake was on when the car was bought. I guess thats why its now carcked and has a rough idle, some one has fitted a 2.5 over a 3inch (must have heated it up).

Thread bump. Great thread guys!

Ive had -5s and GTSS, the -5s felt exhilarating whereas the GTSS IMO were boring. But like many have suggested, depends on your application.

I'm pulling off my GTRS snails at the moment...what fun that is working out of the engine bay.

Mine is far from a weekender which is sad but true.

GTSS setup made 325awkw @ 23psi

-5 setup made 340rwkw @ 19psi (I question this though as that number sounds a bit high, maybe a happy dyno?)

Thread bump. Great thread guys!

Throw those RS' s in the dumpster where they belong!!!!

If anything, that's a tad on the lower side. Ash made 365 ish at around 19 psi IIRC.

Reading posts like this always makes me wonder if i went the right way with my -9's Dam you!!

    • This. The R34 handbrake icon DOES come up when the brake fluid level is low. You might be sitting right on that threshhold. I have been down this diagnosis path and this was the solution (and it was pretty much as full as your picture is to begin with).
    • Unfortunately the cavaet to that is that while any scan tool should be able to read the code, the workshop will need a consult plug to OBD socket adapter. You don't have a location on your profile, where are you based?
    • @Haggerty this is your red flag. In MAP based ECU's the Manifold pressure X RPM calculation is how the engine knows it is actually...running/going through ANY load. You are confusing the term 'base map' with your base VE/Fuel table. When most people say 'base map' they mean the stock entire tune shipped with the ECU, hopefully aimed at a specific car/setup to use as a base for beginning to tune your specific car. Haltech has a lot of documentation (or at least they used to, I expect it to be better now). Read it voraciously.
    • I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.
    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation.
