i've looked everywhere and can't find anything about it...
it says IHI turbo on the outside, turbo spec myav9706, serial number rhc6 190540, parts number 119195-18030... it has 6 fins in the inlet... it has a huge exhaust housing but it has a pretty tiny compressor housing.. here's two pictures... what flange is that? t3?

 

it's a rhc6



comes from a duramax 90-94 diesel.

searching owns you, first ------- link on google

 

i looked at that and it said that the outlet is 2.5" and the inlet is 3".... i measured this one and the inlet is about 2.5 and the outlet is like 2".... it doesn't make sense... i searched that and that's what it came up with... i'm confused..

 

and the flange on this one is different then the one on google...

 

flanges change depending on what company used the turbo. what are you using it for?
