your 1600 is a 4g32, completey different engine to the 4g62 or 4g63
a 4g62 (1.8L) or a 4g63 (2.0L) engine will bolt up to your gearbox, and you can get engine mounts from a rwd that uses the same motor.
problems will be with clearances for the thermostat housing and possibly the CAS that are now on the back of the head closest to the firewall,
you also need to cut and weld the throttlebody flange to the other side of the manifold cos it too faces the wrong way now
if you are electronically inclined you might be able to get a copy of both vehicles wiring diagrams and wire up the ECU for the lancer motor yourself.
http://projectzerog.com/ is a website dedicated to rwd 4g63 conversions... ALOT of info there
