The everything cd009 swap thread.

[Bleakley]

What’s the consensus / review on the Collins adapter kit?
I currently have a KA and the end goal is RB25DET.
With this kit it looks like I can kill two birds with one stone.
(I do see the mazworx KAVQ kit w/ GKTech shifter a good option for KA, but leaves me with figuring something out later for RB)

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.
