So I would have to replace with the HX engine and tranny. Plus convert my automatic into a manual. Sounds like a lot of parts, expense, and expert know-how required. Unless there would be a way to take my current transmission and modify it to match the gears of the HX transmission to go with the HX engine?

I've heard too many horror stories from people changing their own timing belts to attempt to do that lol.
