The motor might with some modifications, a big difference in years and systems, though both are OBD-1. Not even sure the '86 is injected, or is it carbureted? Better off looking for an engine nearer to your '93. There could be multiple issues with sensors and their wiring between the two. Don't use shortcuts, scope it all out beforehand, or you could wind up with a half finished '93 with a forlorn "pond jumper for sale" in your driveway. good luck, Craig.
These are different engines. You are about to open a big can of worms , I have not done this swap my self so if the engines do not look identical (ie DOHC MPFI)on the valve cover and air snorkle, I would look elsewhere for a decent 2002 model car because the 02 is a 2 valve per cyl. car and the 03 is a 4 valve per cyl. car and I can mostly guarantee the ECU wiring harness for them are different. not to mention there are different EGR locations on this 2,2. This is a 'throw away" engine meaning it's not worth rebuilding.been there, got the t-shirt.
are you sure those intakes are inter changeable? if you still have the 98 intake and your 93 block ,sit there and look for any differences in holes or hole locations. another way to check is when it is running remove the oil fill cap and see if it stalls or picks up speed.
I can't give you direct knowledge, from having personally done this swap before, but I can offer you that the 1990 Cavalier, did have a V6 as an option. The 3.1 Liter V6 with MultiFuel Injection System.
Of course, you're going to need the ECM, (Computer), and the complete engine wiring harness also.
My recommendation would be to go to autozone or pepboys and buy a "Haynes" manual on the year, make and model. They go for about 14.99. In this manual it will show you step by step directions on how to take the door panel off and put it back together. That way you can investgate further.
To get a higher compression ratio you can do one of three things.Get domed pistons with valve recesses,mill the block or the easiest mill the head.Take a few thousandths off the head at a REPUTABLE machine shop and bolt it up but make damn good and sure your valves will clear the pistons while at TDC (Top Dead Center) before you mill that head and check after it's milled with the head torqued down,otherwise you'll do all that work only to destroy ALL of the valves AND pistons!Boring it out will ONLY add to your displacement ie. CID/CC/L maybe from 2.2 to 2.3 or so depending on wether or not you go .030 or .060 over if it will handle it.Then larger pistons and rings to match.That will help with the HP pluss mill the head to get 10:1 compression and run 93 octance and she'll purr nicely.Throw in a header,a good exhaust,highflow cat and muffler,knock off the AC compressor,cold air intake and she'll be top notch.Don't know if they make roller rockers for these or not.It really all depends on how far you want to go with it.Hope it helped and good luck boss!!!
