I'm looking to eventually swap a new engine into my 1990 GTS and convert it to manual. Mine has almost 128k miles and needs a pick me up to kick more Honda ass. I definitely want a Japanese engine and need to know the work involved in a swap and manual conversion. What kind of engine is the best? How much power does it have? Is it costly to convert to manual? and what will I need to add to the engine to eventually put in a turbo kit? Thanks.
