Are you the guy that bought that turbo from me? Cuz that was my old turbo. I took those pics, and those ARE MY SEXY HANDS.

The exhaust is definitly .48, as its stamped on it. Im not sure about the A/R on the compressor, but my best guess is .60. If im not mistaken, I believe its a 50 trim wheel.

Its a great turbo, especially for a b16. I could have pulled high 13s with stock b16a2 at around 9-10psi. Unfortunately I cracked a ringland before that happened.

I would have thought that turbo would have spooled great for me, but I have a log manifold, and mine didn't start to spool till around 4Kish RPM, and full boost was around 5Kish.

I have a 79 dat b 210 with a 86 vg30t with some mods. in matter of fact i have posted a mssg abut an up grade for my car subject (vg30t). i can tell you this much @ about 12 psi you can say your are pushing the turbo close to its limits. at 14 psi you have max it out. In matter of fact @14 psi my v6 does 260hp @ the wheels, with a decent up grade 14psi get me 320 or so. hope this help. if not check www.z31.com its all about the single turbo 300zx.
good luck!!!
