lol yeh there are alot of engines that will go in, finding the one u want for the right price is hard tho
if ur located in qld i would be looking at james deans front cut he mentioned ^^^^ cheap as chips and has everythign u will need to do the conversion
even tho going from a 1.5 --> 1.8L doesnt sound like much better power it is, the 1.8L engines have a better head and flow nicer and have plenty more performance parts out there for them
failing that look out for a 4g94 engine (2.0L) they are fairly cheap (in comparison to other conversions) and they are pulled out of newer lancers maybe 2003 lancers so they are quite easy to find if u look long enuf
they are ur most realistic options, if u have $6,000++ then sure go an evo engine or an fto 6a12, but really i think you'll be looking at a 4g93/4 which will give u plenty of power for street with loads of room to upgrade performance with bolt ons in future
