Does anyone know if you can put an older 1.8L carbureted engine into a 1993 Loyale with the 1.8L, if you swap over the fuel injection intake?

Are you talking about swapping over the longblock (block and heads) and installing your current intake onto the carb longblock? If so, then any of the non-mpfi EA82s will work. Might be some issue with EGR, but can't remember at the moment.

it bolts right in. long block is the same, but you will have a lower compression with a carb long block.

eliminate the egr on the carb block and plug the holes on the side of the exhaust port. Use the spfi egr and it's pipe where it screws to the top of the head. The egr ports on the side of the heads exhaust ports is what North Wet is referring to about the egr being different

define: "older 1.8l carbureted"

You mean, early EA82? or EA81? both are possible, but a fairly different project.

It's a 1983 1.8L. But I just pulled my engine out and tore it apart and as I suspected it's the main bearings. I think I might just rebuild it. Decent junk yard engines are hard to find around here. Thanks for your responses.

'83 would be an EA81. Fairly different design (good thing though). the Ea81 doesn't have timing belts. it's pushrod, OHV, with a single gear-driven cam in the center. Much simpler, which makes it typically more reliable.

It is definitely possible to swap the intake manifold and sensors over from your EA82 to have a Fuel-injected EA81 in your loyale.

General_Disorder did an EXCELLENT write-up about putting Ea82 SPFI control system into an EA81 car. it can be found here:
http://home.comcast..../EA81_SPFI.html

Now, keep in mind, the vast majority of that writeup talks about putting the ECU and wiring from an EA82 into an EA81 body car, which is not applicable in your case. You pretty much just need to check out the sections on the intake manifold and distributor modifications, which aren't too difficult.
