complete CV conversion


Recommended Posts

Does anyone know where I can get a complete CV joint kit for a 78 280 w/ a 3.7 LSD in it? I wnat ot replace my current U joints which have a lot of slack in them. Also is there a website on how to do the conversion? Thanks. I want to get this done before the drag races in Reynolds, GA!!

Talk to Ross C at Modern Motorsports Ltd

 

He can set you up with the CV adapters (he can have your 280Z companion flanges welded to his adapter), and then all you need are a left and right 280ZX Turbo (or 2+2) CV half shafts. Ross also has bolt kits for this swap, and bearings and seals if you choose to replace the stub axle bearings. It's probably not a bad idea to have the stub axles checked for rust and cracks at the flange/shaft weld as that's an area prone to failure, in racing anyway.

I didn't realize they were getting scarce. But then again, I did get a couple extra sets for myself a while ago :D .

 

Very interested to hear about a 300ZX CV shaft conversion though. Is that Z31, I suppose? I guess those will be more plentiful for a while.

Im working on a complete z31 turbo mod so it will work on the 240/260 rear struts. so far have the stub shaft installed in the strut housing. If the NA shafts are shorter then the shafts will fit ( i hope) if not im going to have a custom length made. then its on to the brakes. they to are z31 rotors and calipers. heres a brief writeup on what i did

I would hold on to all the ZXT shaft parts that you have, just in case.

Sure, I still have some 280ZXT CV adaptors and if you find a set of shafts they seem to last just fine.....rebuilders rarely have them as noones turned in bad units!

 

The Z31's are intended for use with the NA Z31 axles (anyone have lengths on turbo Z31 axles??) and I should have some initial prototype customer feedback shortly.

 

Here's the specs on the axles I've used so far for the prototypes:

here's the CV measurements I took......taken from the flat face of the wheel side flange to the opposite face of the 'seal cup' at the diff side (ie. add my lengths plus the stub lengths and it would be the total length of the shaft)

 

Z31 NA CV, Right and then Left side, Extended, 17-5/8 ", 17-1/8 ", compressed, 16-3/4, 16-1/2, stubs are 3-7/8's and 3-1/2" long, all measurements right then left side....
