Parts I currently have on hand for use:

89 JDM Integra ZXi
- Transmission Case
- Differential

89 USDM CRX HF
- Differential

I'm using the 1-4 gears of the ZXi (Same gears as CRX Si/DX) along with the HF 5th gear and the ZXi Final Drive (Differential Ring Gear and Countershaft) of 4.4375 which makes for a small difference in shift times.

I need to know if I can even use the ZXi case otherwise I'll have to purchase another case/tranny.

The ZXi tranny case uses the larger Differential Bearings (80 OD x 40 ID x 18 Depth) while the HF Differential used (72 OD x 35 ID x 17 Depth). Can I find a bearing that will work? (ie. 80 OD x 35 ID x 18 Depth) Is that 1mm of depth on each side going to hinder my chances of using the case (trying to save money and time)

Thanks!
John

 

All the bearings I can find on civics/crxs are either 72mm OD with 35mm ID or 80 OD with 40mm ID. I need to find a bearing that is 80mm OD (to fit the case) and 35mm ID (to fit my differential)

Unless I can use the 35mm OD Axles in the 40mm OD Differential... Don't think I can. Swap differential internals? Not likely I think.

 

I have seen tranny cases for 6 bucks on ebay before. They were b-series but maybe you can find one on their for cheap. If you can not find one a good welder can do wonders with aluminum. Good luck.

 

Yeah, the old case is WAY past fixing... it's in about 5-6 Large chunks :D
