You say the engine would be smaller - do you have an particular engine in mind ? If so - what and why ? Is your present engine worn out or ...what ? As curtis said , swapping fwd engines means normally having to swap the entire drive train ( transmission , axles , and differential as well ) unless the new engine will fit the present drive train . Also the new setup would require modifying the shifter , wiring , and all the incidentals that make vehicle work . It can be done but it's a major job ! Keep us updated !
