Exactly what calZ said... I understand where you are coming from. Theoretically you could build a mount and connect s13,14 hubs to a long nose diff. The r200 is a strong diff short or long nose. The parts hanging off of it are the failure points. If I decided to connect a old style stub axle to the short nose r200 same issue. I'm just saying you can alleviate those failure points with the t3 kit. The s14/z32/q45 hubs mount to a bracket then the axle goes in to the hub (if the axle breaks the wheel stays). The older r200 uses the stub axle as the mount which is held together with a big bolt and some bearings. Then the axle is connected to the stub axle. Stub axle breaks wheel goes. Per SlippyD's 2nd question. "Then why do t3 sell the conversion kit for them? Maybe I missed something?" Neverdone gave some detail as to why you might want to switch. Stub Axles are one of the main reasons for me. Wheels falling off at high speed is the kind of stuff I hate.

I am actually not. Stub axles connect to your wheels. Diff axles connect to your diff. You can also run CV joints which does not resolve the issue of the stub axles. That is what I was running before I switched. Stub or hub axles are the weakest point. Replace axles with CV Joints, then replace stub axles with heavy duty billet chromoly or just switch to t3 r200 short nose kit where the wheel hubs bolt to the mount. If the axle breaks they do not come off.

I know this post is a couple years old @SlippyD but just wanted to add my 2 cents. Couple reasons to run a shortnose diff. 1 availablity the older long nose r200 are getting harder to find. 2. Stub Axles. With 280z stub axles, when they break, your wheels roll off into the sunset and you probably end up in a ditch or wall or tree, etc. The S14 hubs stay on if the axle breaks. Considering how much money and time I have dumped into this car it is a small price to pay for that piece of mind. Some people run really expensive stub axles that help with the breaking issue but if for some reason they did break your in the same boat. 400+ HP and a lot of torque I am running the t3 swap with q45 shortnose, the t3 axles and s14 hubs. (kind of the same answer as above but with a bit more detail.)
