[TaKashi]

the final drive ratio of the DJ25 tranny that comes with B21A1 is a 4.27, short gearing much like that of a gsr tranny.

I've never heard of anyone using that tranny on a b18 so i cant be positive. Why not sell it and get one that you know will fit??

it won't fit. the mounts and everything for a 3rd gen prelude are waaaay different than any other b-series
