Garrett Marketed Gtss Equiv - Or Is It ?

[discopotato03]

Hi all , I was sniffing around some online compressor maps and came across an interesting thing .

I've seen people here speak about the Garrett marketed equal as the 707160-7 turbo which is a replacement RB26 turbocharger but I reckon its not the same cartridge (CHRA) as the one HKS speced for their marketed GTSS turbo .

The CHRA used in that 707160-7 is the 446179-54 , I believe the real GTSS CHRA is the 446179-65 and the good oil is that Garrett also sell it as turbo number 707160-9 !

I'll post the links so you can see the two compressor maps and compare . Also take a look at the dimensions of the two compressor wheels because they are not as different as the comp maps would suggest .

At a glance the two turbos look (I think) identical because they appear to use the same housings in the same A/R ratios .

At Freshalloy.com someone has a thread asking about his genuine GTSS turbos because it seems these turbos don't have "HKS" cast into either housing , the actuators seem to have HKS stencilled on them .

That feller quoted 707160-9 on his SS's ID tags which is a bit interesting isn't it ?

If you look here, It says the same.

It all points that way , I reckon if I had an RB26 and wanted GTSS performance at a Garrett price I'd be asking for a pair of 707160-9's . People say that HKS actuators can be bought for them as well .

Cheers A .
