Picked up this turbo locally, I think it may be too big for my project, but should work well in a rwd car utilizing the original outlet elbow. Came out of a wrecked Mazda Cabover Diesel, here is a link w/pics:
Comprssor a/r is .60, turbine is .84, I am not sure on the wastegate actualor pressure or the trims. I can probably get a small regulator and pressure gauge to find out though.
