OK, it's a Garrett turbo with a 52mm compressor wheel. Can't determine a part # from the A/R (area to radius) ratio and foundry casting marks on either the compressor cover or turbine housing.
reading about compressor and turbine A/R can be done here:

This spec data from Precision has it maybe being a TA-52.
The TA-52 would need a higher rpm stall converter than stock. Also, for any turbo you are looking at, you'd want a turbine housing A/R of .63 and not the .82 housings. The 82's are fine for top end rpm at the track, not so great on the street.
For a stock or nearly stock powertrain, the stock turbo will handle up to 20 to 22 psi boost. Upgrading to a TA-49 over stock does not make much difference. Only feel a difference once boost is greater than that 20 to 22 psi level. maybe get 20 HP more with TA-49 on the street at 16-18 psi boost with a TT chip.
Search feature on the site is working again - maybe do some reading. On a stock powertrain, an upgraded turbo by itself won't do much. In some cases, it can hurt. Cost wise, a rebuilt stock unit is the way to go if you will keep the boost level below 20 and controlled by the chip, whether TT or the factory chip.
