Garrett GT2560R small difference (1-1 vs 1-2)
#24
#27
Just for info (I'm not IDing this turbo!), I believe the T28 Journal Bearing predecessor to the GT2560R is the TB2815.
As fitted to the SR20DET in the Silvia/200SX (S14). Same compressor/turbine dimensions as the GT2560R.

Wow, the 3" exhaust does wonders then! I may have to add to my shopping list as mine def comes on far later, I top out just under 1bar (~13psi).
I just used generic ebay alloy inlet/outlet adaptors similar to above, they came with basic gaskets that seal fine. Personally I'd avoid the Kinaguwa Turbo outlet shown as it has that superfluous wastegate port. As per various threads on here, it appears to be a better option to take the Wastegate feed from just before the Throttle Body, NOT direct off the the adaptor as show.

it's not shocking at all. there's at least the same amount of exhaust pressure as boost pressure, plus all the extra pressure from the combustion. I'm sure the exhaust pressure before the turbo is double the boost pressure, then you're trying to force it all out of a 3" pipe while it's cooling, slowing, and expanding.
