So I found a couple interesting things

1. In rockauto they sell a 300zx turbo driver axle for $90. Is this the unicorn axle? Whats the catch?
NI8399 is the brand new Q45 driver side axle
and
NI8467 is the 300zx Twin Turbo axle Driver side

ATM my plan is email(ed already) the axle company (trakmotive for example) ask them whether this NEW axle is strong enough like the OEM axles to support 800horsepower etc...

2. In car-part.com if you search for Q45 axles it differentiates between 90-94 and 95-96. According to every website they should all be the same 6-bolt axles for 3.54:1 ratio diffs. But car-part.com will show you MANY people have the 90-94 axle. and NOBODY has the 95-96 axle. ???

edit: I found this:
" Possible exceptions for the J30 LSD fitment (cut-and-pasted, from Asad):

From a search on www.car-part.com for a 1995 J30 VLSD...the years that come up in the interchange are:

1994-1997, with production dates "from 1/94" often given for the '94s (meaning it changed during the '94 model year)... and "Thru 6/96" given for '97 diffs (likewise, meaning it changed sometime in the '97 model year)... In addition, some of these diffs have in the comments "3.92 ratio" or something to that effect. If you search for a '97 J30 differential, you get 3 options: "Thru 6/96", "From 7/96 thru 11/96", and "From 12/96"... meaning there were actually TWO changes during the '97 model year. What those changes were...who knows???"

So... Who knows? The site that I got that from has it all wrong too. its rlly old.

update:
so here is what I wound up doing. I was able to contact "trackmotive" and asked about axle strength, and they gave me the "up to OEM standards or better" speech so I guess its worth a shot. I bought a brand new 300zx driver side axle from Ebay "trackmotive". then I bought a complete Q45 subframe from a junkyard Q45 1994. It didn't have ABS sensor in the input flange area so everything (driver side axle, hubs, and differential 3.5:1 ratio, my same driveshaft length) bolted right into my S14 240sx and I used that new driver side 300ZX axle for the driver side of the 240sx. The only 'custom mod' necessary was the drilling of the input flange of the 3.5:1 diff. I was able to keep ALL my stock arms in the rear end. Which seems like it works really well for launching this V8/4l80e on a 3.5:1 ratio
