compare to a us sr20de standard tranny a sr18 tranny seems to have shorter gears but longer final drive/ sr20de longer gears but shorter final drive compare to a sr18 tranny haha.. so they're both different but with same results.

i hear ya...with my old DE i could do 30mph 1st gear and only 60mph in 2nd....with stock rev limiter

yeah, i will prob be stuck with 7.2s 0-60mph even with sr16 trans installed haha. we'll know soon enough

Wouldn't be cheaper to get the final ratio from gspec?

4.44 gear ratio (2.0 w/LSD only),

Gear shaft and ring gear from JDM model with 4.44 gear ratio. Must be a B13 or B14 originally equipped with LSD. Also fits G20 thru 1999 if originally with LSD.
