Seems to be a lot of f***in? around with this Z33 trans. Other option I?m considering is R33/Z31 transmission w/ Alpha Omega for the KA then just switch to RB25 bellhousing when I go RB25.


@mint240 ?> Regarding diffs. Taking into account cd009?s 6th ratio @ 0.794, any diff. 3.5-3.9 would be good ballpark (for street/highway) and depending on preference and application. I myself plan on going w/ a late Q45 @ 3.69 or a Ford 8.8 @ 3.73
I have a thread on diffs and am pretty well versed on the combinations especially for S13. If you need a hand message me. Q45 diffs are cheap btw @ like $250 or less.


I saw somewhere that using a piece from the xterra truck I believe changed the diff gearing to something tolerable. Any input on that? I just went CD009 on my JZ and I already have a Kaaz 2 way I?d like to preserve
