    Forgot to say- This turbo is a little... weird- I know AGdieseler said that there should be no play- in this case, there is no play, up down left, right... but it is a little stiffer than I remember turbo's being. Im familiar with most import turbo's (made by IHI or Turbonetics) but this one is a lot stiffer. Its not that it takes much force to spin, but it certainly doesnt free wheel like those either.

    Should I be concerned? Should I try and run some ATF through the oil passage and try and clean things up a bit?

    if it's been sitting for a while, I would oil it and spin it a bit to loosen it up.

    I would be concerned if it was that stiff.

    Nice. I think you'll like your GM8.

    Definitely squirt some oil over the bearing and give it a spin. If you're still unsure, turbo shops usually check the condition of a unit for free.

    Next, I would start fabbing an intake (or pick up a 6.5TD setup), then an airbox, an exhaust, and so on. Just keep acquiring parts as the pocket book allows.

    Is this truck parked, or is it a DD and you are going to have to do the swap all at once in a weekend?

    Kinda a little of both, I have other vehicles to drive during this time so its not terrible. Im not going to begin until I have all the parts anyways. I just wnated to make sure that the turbo wasnt toast.

    Little Update- I've got a Short ram and k&N cone filter to bolt up directly to the turbo. THe intake is still baffling me. How big of a diameter do I need for proper air flow?

    Do you mean the intake to the turbo, or the intake to the engine. Try for 2.5-3" and 4" respectively.

    I meant intake into the turbo- Intake manifold I already have a J- Code (no divider). I went for a 3.5" intake. It was free! /forums/images/graemlins/rotfl.gif
