Hi Guys - What kind of exhaust housing do I have here?

I took it to get rebuild but was told it needed to replace. Also, any leads where I can buy one??

Also, is this a 14b or 16G?

Thanks.

Found the info | https://www.dsmtuners.com/threads/td05h-turbo-part-numbers-14b-16g.313105/

The turbine housing is 7cm2 per the turbine housing: 78-11830. And its a 14B.

78-11830 is a standard 7cm2 housing, the D2 casting. Your compressor wheel has a 68mm exducer according to your measurement but that's all I can tell you about it without an inducer measurement.

The assembled turbo is a 14B with a turbine housing and actuator from a knockoff 16G.
