Hi guys, I'm looking at buying a 91 Loyale with a blown ej22 in it. The engine in the car is a 95 and the harness is from 96. I have an ej22 from a 91 legacy ready to bolt in. Would I be able to use my engine with that wire harness? Or would I have to change a bunch of stuff?

From what I remember off the top of my head...

 

 

You'll have to swap all the wiring on the engine, including the crank/cam sensors. The engine/wiring in that car may or may not have provisions for an EGR valve, but I think your '91 engine will have it regardless, worst case, you have to block some or all of it off.

 

 

The '91 engine definitely will have dual exhaust ports on the head, the '95 engine should as well....but depending on the production date, or whether it's actually a '95 (we've probably all bought cars with an engine swap, or even just loose engines, that turned out to be different than advertised), it might be single port. In which case, you'll need some exhaust. The 90-94 2.2 stuff is a pretty different configuration, but if you get a "manifold" from a 2.5 (or aftermarket, Borla or similar), it should bolt onto the existing cat pipe with no other mods.

I still have the donor car my engine came from, so the exhaust manifold isn't an issue.

 

So swap the wiring from under the intake, cam/crank sensors, and possibly block off the egr?

My bad, the car I'm looking to buy is a 91 loyale.

no problem.

use the ''new block with heads,

and bolt on the existing intake manifold with wiring.

it will match perfectly .

 

the only possible issue would be if the existing 95 ej22 has EGR and needs EGR.

then you would have top do the EGR ''work around"

since the 91 ej22 does not have an egr port threaded in the head.

but the work around will correct that, if needed.

and it is easy enough to do.

 

so check to see if the existing engine has EGR.

or not.

the 91 engine will fit and run.

no problem.

 

good luck.
