Please help identify turbo

[OneQuikSix]

I am trying to identify an old Precision turbo with the old H cover. The compressor looks exactly like the picture in the understanding turbos thread that is stickied at the top of the page. The compressor cover has a 4-inch inlet and 3-inch outlet. I have the compressor cover off of the turbo, but I am not sure where to measure using my dial caliper. The base of the compressor wheel measures exactly 84 millimeters while the small part of the compressor wheel measures 63 millimeters.

Thanks.

So after measuring the wheels, it appears the compressor is 63 mm and the turbine is somewhere around 67 mm. Anyone know if this turbo is worth hanging onto? It's obviously got a few miles on it but ran fine and didn't smoke when I took it off the car.

I'm not exactly sure what the name of that turbo is due to the compressor housing,but it should rip really well.
I'd keep it or sell it to someone who wants to upgrade.

After some research I found it is an older Precision unit with the older H cover compressor...before they started casting their logo into the housing. I'm torn because I don't know how this old unit compares in efficiency with some of the newer units with respect to things like backpressure and such. I have a feeling I will end up running it out of sheer morbid curiosity!
