Gtr Gt-ss/707160-9 Turbo Pics ?

[discopotato03]

Hi all , does anyone have pics of the turbine side of an RB26 type HKS GT-SS turbo - or the Garrett GT2560R 707160-9 which is suppoed to be exactly the same thing ?

I'm just trying to find out if their turbines are the usual base model Garrett GT25 BB turbine style - 11 bladed and the fronts of the blades lead forward - you'll know what I mean if you've seen them .

The Garrett maps of these turbos (CHRA no 446179-65) look pretty good BTW .

Cheers and thanks , Adrian .

I can get some for you tonight if you still need 'em. got a pair of HKS GT-SS at home. and another set on the 32 in the garage. they are pretty good. spool up pretty hard. 15psi at 3700rpm.

Yes Beer Baron that would be much appreciated .

I've been reading up on small/medium sized Garrett GT25/28 based turbos because I need something smallish for my daily dinosaur Subaru Leonie RX Turbos engine .

I looked through the maps on the turbobygarrett site and it looks to me like the 707160-9 turbo is exactly the same as the HKS GT-SS GTR turbo - except possibly the waste gate actuator .

Could you possibly confirm for me that the GTR GT-SS turbos ID no's are 707160-9 and or CHRA no 446179-65 .

Also interestingly the compressor wheel OD is slightly different (59.4mm 56T) to many BB GT25/28 based turbos that usually have 60.1mm OD 60/62/63 trim wheels . It makes me wonder if it was a special cooked up by Garrett at HKS's request .

I'm also going to talk to Brett at GCG to see if its practical to fit the lighter/larger trim GT28 NS111 turbine to this cartridge and use the more common SR type GT28BB turbine housing . These housings are a little wider at the inlet than GTR ones and the mounting holes are plain rather than threaded for RB26 apps .

I dont suppose I could talk you into showing us a pic of the compressor wheel with the housing removed ?

Cheers and thanks , Adrian .
