I've got a 1990 Geo Tracker I was trying to find a replacement engine with a little more pep than the 8V 1.6.. Anyone know if the GSI 1.8 DOHC would fit? Or does anyone know any easy dropins that can replace the current engine? I was trying to find one of those japanese engines that are so cheap but it seems hard to catch one for the 1990. Also I have a 3 speed auto, anyone know any tranny's that would be a bump up? Maybe 4 speed or 5? I dont like running at 3.5k rpms or higher on the highway.. kinda kills the theory of getting good mpg.

Hopefully this forums thrives a little.. I don't see much going on in here but there aren't many options for tracker enthusiasts.

Thanks in advance.
