best tranny

ok here's the thing. my friend has a 92 dx hatch, with a b16a in it and has a Type R tranny in it, so down the 1/4 mile ive seen it take on turbo 2000 SI, and many others expensevly modified hondas. and the car is only equiped with a dirty K&N intake filter and a busted cluth and still runs like hell, when it shift to 3rd gear it launches forward, and all we can think of is the tranny ratios. so, heres my question, what is the fastet tranny in the 1/4 mile for substitute on the original s20 that comes with my 94 ex coupe? i know theres many racers out there that have tried diferent ratios on many civic so let hear how fast can go.
