check out the arch rival website, honda-tech. com, couple guys there have designed, an adapter plate where you can mount a B-Series tranny, to an
H-Series block, then u use hasport B-series mount kit, dont have to convert to cable shifting, use shift linkage, dont have to chop frame, almost straight bolt in, and from what they've said 100 times better gearing with B series tranny, save 8lbs on swap, and i've talked to mechanics at my work and i guess adapter plates are old news, so it seems to make sense, and also it looks like a few people are picking these up so wait for there feedback first then make the call, thats what im waiting on right now, seems to make sense, hope this helps, maybe i confused u
too
