the best would be a cable b16 tranny, it would have the shortest gears of the b series cable trannys. the best hydro tranny would be the ITR tranny. but it really depends on what you plan on doing to the engine. for boost, i'd recommend a hydro gsr or if you can get a cable gsr, stick with that. for all motor the ITR and b16 have the shortest gear ratios. only thing is that the 5th gear is pretty short, like 4500 rpm at 70-75.
