w5m332 means they are for turbo AWD 4g63 powered 1G, GVR4 and evo 1-3 (don't know about evo iv and beyond, anyone?).

nq -> is for the GVR4 (US and JDM)
np -> if the the US 1G and some 2G cars (up to 96; in '97 MMC switched from np to mu for the 2G)
c50ph -> is the switchable tranny (2wd/4wd)
c51ph -> if for the 88-89 JDM VR4 (early GVR4s) and select foreign market (a specimen was reported in Australia for example) GVR4s

All of the above are compatible with the GVR4 3 bolt and the 1G 4 bolt rear diffs.

wq -> is for the GVR4 RS and the evo1
evo2 and evo3 -> trannies each have letters that are different from all of the above and from one another.

The wq and evo2 and evo3 trannies DO NOT work with the US GVR4 3 bolt nor the US 1G 4 bolt rear diffs. The above data was gathered from multiple lists over a period of two years. I have found no exceptions to date.
