It was on a shelf. Not really much to look at... almost the same as the regular Garrett beside it... but when I saw the GT28RS label, I stopped in my tracks... mukhang familiar, ah...

Sid told me to try spinning it... compared to a regular turbine, it feels like it's free-wheeling.

It's bolt on, I suppose... but I don't know if it's application specific or a universal fitting (I'm no turbo expert.)
