Hey guys,

I really would like to know what are the Garrett equivalent of the HKS GT-SS turbo's?

I have researched for a bit to find many mixed results that they could be either the -7's or -9's

based on the source. However, from my understanding the -7's are actually closer to the

N1 turbo's off the R34 GTR's.

Also, does anyone which is suppose to output more power between the -7 and -9's?

Thank you.

GTSS is EXACTLY the same as -9. It's the same part without a pretty badge. This information is in just about every thread started on this topic since SAU started.

For the rest, use the search button. It's been covered so many times, in great detail. There won't be a single question you can think of that hasn't been answered already on those turbos.

There's a 300kw GTR thread, 400kw thread, RB26 dyno results thread, 7's vs 9's thread (not this one) plus more. There's ECU threads, Fuel system threads, exhaust threads, dump pipe threads, intercooler threads, air box threads, clutch threads, radiator threads, brake threads, wheel size and fitment threads. It's all been covered before :)

This may seem rude, but members on here who have taken the time to give very detailed answers and information in the past will find it rude that their past contributions are neglected by other users who are too lazy to take the small amount of time to search when they've given their time to answer the questions already.

Le sigh.....

Will -9's (GT-SS) go well with a 2.8??? :P

No one has asked that yet!

My guess is awesome low to midrange, then a choked top end and drop off after 6500ish due to smaller hotside compared to -5's, and smaller cold side witth more heat if you put in more PSI.

+1

....but, They will make more hp than the -7 due to the larger trim on the comp. And a -5 might be too big for him

gtr.uk confussed me so much mate, there quite old posts aswell but people keep saying gtss are -7s ect ect, or they say -7 is bigger then -9 ect ect

The pommie forum has really taken a dive in quality over the lasts few years.

-9's are SS's without actuators and a badge.

The difference between HKS GT-SS and -9's is nothing. GT-SS used to come with HKS stamped front compressors but now they have the same cover as Garrett -9s (and have had it for ages now). GT-SS come with adjustable actuators, -9's don't come with any actuators (Garrett do make bolton adjustable actuators to suit though that can be brought seperately).. although if you wanted standard actuators on -9s then you would want "-1's".

    • I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.
    • Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.
    • Thanks @jtha7 I will have a look around tomorrow but it is a prick of a spot. These are some photos i tried taking 
    • I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
    • Hi @Chupapy i had several leaks from coolant pipes being corroded, i also had one leak on back of the head onto transmission. For me that leak was from the turbo water line. Follow the line to the back of the head The hose and metal pipe had perished these are the best pics I took of it at the time
