I recently blew the engine on my 2.3 but im on a real tight budget and it costs too much to buy the same size engine (about $2000)... does anyone know if a 2.0 can be swapped in directly? what kind of adjustments would I have to do in order for it to fit correctly? im pretty sure ill need to get the ECU but not completely sure

feel free to post links, vids, pics or any additional info that helps.

thanks
