hmm. . anything's possible... but I hope you know how to weld & fabricate lots of stuff, like driveshaft & axle flanges, mounts, etc. I don't know the ratios in it, but since Infiniti Q45 is a pretty high up luxury car, it's probably a good quality differential.
but I bet it'd be cheaper just to get an LSD from a 84-89 turbo 300zx.
then again i still have my stock r180 and i've never touched it other than to change oil. so what do i know?
Makes CV adaptors and Moser custom shafts
It may be a little more expensive to do than a 300zx R200 LSD, but they are easier to find, and are much stouter and stronger from what I hear. You can also get a R230V from a 300zxtt (3.7 ratio) which is bigger than the Q45s.
Here's a side by side comparison of a R200V and a R230V
My mistake, it was 90-96 having the R200V, not 90-97
The Z Doctor,
Were you running into any problems with the diff? Did you fabricate everything yourself or did you use adaptors, etc. from Modern motorsport? Just wanted to get an idea since I'll be doing the swap in the future.
I'm a little busted here. I didn't do it, one of my employees did it. He fabricated everything (driveshaft, front mount, mustache bar etc.) The axle problem was approached by shortening the stock halfshafts by one ball, and welding the four bolt ujoint flange to the machined-out stub axles in the R230. Crude, but effective......
Thanks for the insight. My R180 is starting to pipe up with clicking already and I'm in just my first 500 miles with the new 83zxt motor. This truly is a perpetual project. My wife could be a threat to my Z's health about now.
