Looks like an old turbonetics with a stock turbine and a .82a/r ex housing. Basically a mismatch of wheels and will hit exhaust choke flow before the compressor is done. I can't remember what compressor they used but the turbo is the equivalent of a Garrett stage 2. I don't think compressor is a 60-1. If it measured 59mm inducer it is. It will be really lazy on spoolup with a stock converter. There are cheap turbos available with a lot more mass flow potential
