I just bought an LsVtec engine from a friend. It is a b18a1 bottom end from a 93 integra with an si head, the engine is already obd1. I just need to get mounts, tranny, axles, etc... but I need to know if I can use any hydro tranny? I always thought that I could just bolt up any hydro tranny from any b series motor. But the guy I bought the engine from said something about the "input shafts" being different??? I don't know what this means. Is he just stupid or does that have something to do maybe with the axles? if so, I will just get axles for a hydro tranny, right? Or could he mean that the clutch or flywheel on a motor that came with cable tranny won't work. If so, why couldn't I just replace the clutch/flywheel with one for a hydro tranny? Does anyone know what he is talking about or has anyone done this before first hand? cuz i can get a really good deal on a hydro gsr tranny right now, and I need to know before I buy the tranny. Sorry this is so long but I want to make sure people understand my question.
