It's a 60-1 compressor and t04 69 turbine. It's good to high 10's or faster with the right stuff. It's about the same as a te62 but the 62 uses a p trim turbine
You would measure the wheels inducers/exducers and give the blade count. The 60-1 compressor is 7 blades and if an imaginary circle was drawn around the inducer it would be 59mm
My old 85 with a funky inter cooled setup went 123-124mph at 25-26# with a TA-54, mild cam, 3200 stall and other supporting mods. I was pretty happy with that turbo way back when (10+ years ago)
