Copied from drift works.

Good for over 500bhp and with the ideal and rare as fuck 10cm turbine housing (about .73 a/r), is pretty much what I use on my RB20, and would be a weapon on a SR, RB, 1JZ, etc.

Considering it's a beast of a turbo, it spools like fuck, I see boost under 3000rpm and full boost by 4000rpm on my RB20, and they well known to be worse at spooling turbos than pretty much any other 2ltr, and it's spastically fast too- I can hit 7000rpm in 5th from a 20mph rolling start within 400m! Got to be around 450bhp and it's running 22psi. These are good for 45psi.
7 blade HX35 compressor (ie good for 600bhp no worries), but turbine wheel and housing is a little smaller than a 12cm HX35, but tbh not by much so it might be capable of not much less power, though I'm not sure.
T3 flange.

They internal gate, but TBH 99%
of the world would just wire/weld it shut and run an external gate.

And they sound fucking insane, mega turbo spoolup and spooldown noises.
