I'm new to the import scene and I'm thinking about swapping a H22 prelude motor into a civic...preferably the 99 or 00 model(is this referred to as 6th generation?) I see the H22 motors on ebay for anywhere from $2000-3500. They say they come with hydraulic transmission. What do they mean by "hydraulic" transmission? Also what else will i need to complete the swap? (axles, etc) Any advantages, disadvantages? Sorry for all the questions but I'm a newbie. Thanks guys
