AFAIK, should be exact same gearing, including primary and final ratio, for those 2 boxes. Can verify by stamped code number. Here's a prev post by me:

C900's gearing, info/options

Checked workshop manual and various sales spec's. Best I can tell for USA 5-speeds:
-> all c900 turbo and 16V-na had same overall gearing, resulting in 68 mph at 3K rpm. The 8V-na had taller gearing, getting 73 mph at 3K. Seems
euro 16V-T's got this same taller gearing.
-> final drive ratio is 3.89, except 3.67 for M82-88, all markets.
-> USA primary sprocket overdrive ratios:
M80-81, .78 all
M82-88, .84 turbo(all) and 16V-na
M82-88, .78 8V-na
M89-93, .78 all
So to drop revs in M82-88 turbos, just use the .78 sprockets. For others, .72 sprockets are used in M89+ euro turbos, .... should be getable.
