    Hi there,

    Wondering if the front diff from the W4A33 transmission fits into the W5M33? I'm currently running 3.545 rear and want to swap over to 3.307 for drag racing.

    Thanks.

    no. and you dont want that. All the faster gear is gonna do is eat up clutches faster. If you really think you need to try it, you need a front and rear ring/pinion from a w5m31 that has the 2.864 rear. I tried it as an experiment, and unless you are running some kind of small turbo stroker, it's all wrong.

    Thanks for the reply. It's for my big turbo stroker. Was just trying to trap a big higher in 4th. Sounds like I should just stick with the 3.545.

    Just curious since you stated it, but you're saying you ran the auto front diff/ring gear, or the 2.864 ratio?
    I'd be interested to know what the 2.864 came from, galants?

    Awesome, thanks Hiroshi!
    Biggest reason I was curious is the auto front diff is vastly different from the manual, though I have considered seeing if custom work could be done to make it usable. Honestly I believe thetthe ringbring gear is too large in diameter, and a custom pinion would need to be made.

    I'll have to keep my eye out for the RVR stuff.

    Yes I ran the 2.864 stuff. It came from my 90 galant gsx. it's litterally too tall to use. 5th gear is 90+

    Understood, I'm interested as my next plan is a tq build and cruising rpm being low would be great.
