Hi all , The HKS GT-SS is getting a good rap in Australia for SR20's as being a good mild punchy upgrade . My searching shows that it has the 76T NS111 turbine with a 56T 60mm (GT30?) compressor so similar cartridge wise to the GT28RS but with 56 rather than 62T compressor . I am hoping that someone with one can give me the cartridge number from the turbos ID tag ie 446179-00xx . From some of the turbo gurus is there also any Garrett GTBB CHRA's that use smaller trim ie 52 or 50T 60mm compressors with the NS111 turbine . I ask because someone here is trying to find the ultimate turbo to park behind a 34mm restrictor for his class of motorsport .

Cheers and thanks Adrian .

Edit : GT-SS compressor 60 trim not 56 .
