obviously they are from different years, but my question is, is it possible to take a h22a4 sh model block and use an 1994 h22a (JDM) internals (crank, rods, pistons, journals, etc.) and the h22a head with out any problems...also why is it that people say the trannys aren't swappable aren't they typically the same scing both bolt to the h22 block??
