    Drivetrain tech questions on 1990 4x4

    So i have some questions on my 1990 Mitsubishi MM 3.0L 4x4.

    1) I have the V5MT1 trans. What is the power/torque limitations of this trans? Seems pretty stout
    2) my front diff is an 8". Starions seem to be limited. can I swap out with 1st gen MM rear diffs? Are they not 8" too?
    3) sounds like my 9" rear gears might be interchange with ford 9". Is this true? Also I know that the second gen monteros have a higher pinion and not swappable but are their limited slip diffs still interchangeable with mine?

    I ask these questions because I will be going 1 of 3 directions depending on my limitations. I will be going:

    -6g72 TT. I have a complete TT block in my garage. This would be the most complex due to the exhaust and location of the turbos. Still not as bad as customer manifolds on a 3s.
    -6g74. I have a local provider with one that I can drop in along with the matching wiring harness and ECU.
    -6g75. Little harder to source, but I can get one. Parts are a little less common, but still solid motors. With these last two options I would first go N/A and later explore going TT.

    My background is with the TT 3S's. I have a couple fun projects in the making and decided to take this one on as well. Could really use some answers on the above questions, so I can get this girl rolling.

    My other project


    Appreciate your time.

    Somehow I feel I may have asked too many questions in my first post.

    Thanks for the link. Saw that one earlier. Good build info for guys going from 4 cyl to 6. Hopefully he

    Still could use answers to the drive train questions mentioned above as he didn't mention those.

    You didn't ask too many questions in your post, but the main question is ...do we get to test drive it when it's finished?
