Hey Guys,

I'm about to build a ZC/Si Hybrid Tranny and am just trying to gather info. I've got a 91 CRX Si Tranny and a ZC that I've had in my car. I opened up both trannies and have read my Haynes manual about 20 times on tranny overhauls. Has anyone done this before? Any pointers or things I should do? Please help me out.
I'm going to use the ZC 1st-4th gears and the Si 5th gear and FD. Would I use the Si Shafts since I'm using the Si FD or would the ZC shafts be used because I'm using most of the ZC gears. Is it critical to replace the bearings and syncros? Are there just certain things I should look for on those that'll tell me if I do need to replace them or not?
Please anything you've got that'll help would be awesome. Thanks in advance.

Later, Ahknodd

 

last tranny I did I just put the si final drive into the zc trans. You can use either shaft. I've he to rob shafts out of parts travvies from people having bent rails from being installed in correctly. don't force anything it should go together easily
