Nissan WC T5 for L6

[ezzzzzzz]

I've been busy building a WC T5 for my SC'd L6 project. The premise was easy enough. Build a close ratio gearbox, bolt on the bellhousing, top shifter plate and tailhousing. I've found a few stumbling blocks but nothing too serious. starting at the front the bearing retainer required a bit of reaming to clear the larger OD of the WC input shaft. The top shifter cover was a direct fit. I knew I'd have to relocate the speedo drive gear using shim stock to build up the OD of the mainshaft which is a simple task. After I cleaned up the tailhousing I decided to replace the rear bushing. Whoa, the new bushing is much larger than the old one. I mic'd the splines of the mainshaft and then tried the old driveshaft. No go. I realized that I'll need to mill out the tailhousing for the new bushing. Because that thins the casting wall (about .125" but primarily on either side but not top and bottom) I think I'll have to tig some additional aluminum in those areas to build up the thickness prior to milling to add strength. It then occured to me that speedo gear wouldn't fit either. I ended up turning down the Ford gear OD and opening up the Nissan gear for a press fit and super glue. I know there are other transmission options but I wanted to try something a little different that wouldn't require cutting and banging on my tunnel. There's a KA conversion I built a while back installed but the 3.90:1 r&p makes first gear pretty much useless.
