Ok, I'm trying to make chicken soup outta chicken ---- here, but I've got a 94 Si tranny with a busted housing, think car wreck and sheared bolt holes, and I've got a 92 Cx hatch. Are the two manual transmission casings the same? Will the Si internals fit into the casing of the Cx?

Bone1

internal can be swapped IF you know what your doing, mainshaft WILL have to be reshimmed.

It's been covered a little on D-series, I just posted last week what you'd generally have to change.

Bone, what is your name on D-series?

This 'hybrid' tranny will be going on a Z6, all this is on the cheap and easy. How hard would it be to take the Final Drive outta that Si tranny, put in the Cx tranny? Would it require the shimming? I don't have all the calipers and dials to do something like that, and I don't want to spend the money. I know 2-5 gear is different, but they aren't off in left field like with the Cx FD.

Also, since I'm gonna be opening this sucker up, and I plan on a turbo I'd love an obx lsd. What do you guys say about my situation? Is the cheap and easy fix for the 5-speed would be take the FD outta the Si, and take the Diff assembly outta the Cx. Then throw in the lsd with the 4.25 in the Cx tranny. Would this FD swap be possible? Would one lsd fit both ring gears and cases?

OBX won't fit small bearing CX case.

$650 Quaife I have sitting here would work

FD swap is easy, no shimming needed, but the 1-2-3 ratios will still suck, 3-4 will rock if you highway racing from a 75mph roll.

Gotta do the math, read the helms, and take pics.

I see things in pics most overlook, like the ZC tranny thread on D-Series with ebay link, I called it a Y tranny and amazed everyone. If anyone took the time to PAY ATTENTION.....they'd seen the same thing.
