[96-GT_Josh]

Ok, So I've had this Garrett Turbo for about 6 years now sitting in my garage. I got it off a good friend of mine who works on F-Bodys and he was going to twin rear mount it on a Camaro.

It is a Garrett GT25 Ball Bearing turbo, oil or water cooled. Serial number 700716-5 I searched and it is from a 99 Isuzu 4.7L truck. Internally gated at 7 psi. Brand new so no shaft play or nothing.

Comp side is a A/R .60, Turbine is a A/R .80. No trim specs.

I did look on turbos by garrets website and the A/R sizes are almost identical to a GT2860R. Turbine on mine is .04 smaller, or the GT2860R has a turbine A/R of .84

1: How do I find the trim size
2: What rpm will this hit full spool
3: What RPM ranges will it be good for
4: Do I have to oil and water cool it or can I just choose one or the other?

I'm going to kinda answer some of my own questions here but I just want verification.

The website says:

GT2560
Horsepower : 200 - 330
Displacement : 1.60L - 2.50L

GT2860R
Horsepower : 250 - 360
Displacement : 1.80L - 3.00L

I know it is too small for the GT but my younger bro has a 94 Probe GT and he is interested in it and I wanna make sure it will work for his car before I give it to him and he spends a lot of money on a turbo set-up.
