Hello guys newbie here. I'm having trouble finding what turbo a have, to start of with the compressor side has part number 20192 as for the exhaust side it has the "T" casting on it and the A/R .81 and for the backing compressor backing plate its not the blue, red and gold. its just the aluminum color. I found some numbers 409322-12 dTc and its has a ribbed casting on it. as for the center section of the turbo it has the oil passages and also water passages. as for the compressor wheel these are my measurements from a micrometer the inducer is 2.244 and major is 2.743. this is the best numbers I can get making sure its accurate, but its difficult since the blades are curving so more info the inducer blades there are seven blades and for exducer there are 7 as well just throwing that in there. my goal with this turbo is to make for 450 480 rwhp on ls1 fbody if possible ill will try to post pics as soon as possible any help would be great thanks

Is there a serial number sticker that has a number beginning with T- like T-22222?

No there is not I looked at this thing and no luck the unit seems to be in great condition , my goal is to find out if it can produce around 450 to 500 rwhp without killing it. thanks

Well the 20192 on the compressor side indicates its a T04B Super H I'd need the exhaust wheel meausrements to tell you what that is. The compressor map for a T04B Super H is below.

The compressor is good for about 500 CHP of air but based on what turbine it has it might be a bit too small for an LS1. You'd have to run a fair amount of boost on that compressor to make that power. Typically T04B units would be used on Hondas or other 4 cylinder cars. I typically wouldn't got much smaller than 60-1s for an LS1
