Thanks

IIRC, the heads on the 2.2 and 1.8 are the same, so as long as the engines are of the same years , or matching years , it should.

yes it'll drop right in and bolt right up. some notes below:

 

there are some minor issues. the EJ22's usually have single port heads and the EJ18 has dual port heads (don't know if there are any single port EJ18's but i've never seen one).

 

95 automatic EJ22's are the only ones with dual port exhausts and EGR.

 

if you use a single port exhaust EJ22, that's no big deal, you can just swap an EJ22 exhaust manifold with it as well. that opens up your options to 95 automatics and 96+ EJ22's. and maybe even early EJ22's, but i'm not as familiar with those.

 

or you can ignore the EGR issue (i hate the EGR system anyway, it's like installing and increasing unreliability - so i intentionally install blocks without EGR or remove the EGR altogether).

 

so you'll need to decide what you want....retain the EGR, or not?

 

the easy way is to install the EJ18 intake manifold to the EJ22 block, it bolts right on then retains all your original wiring and plugs right in - plug and play. personally the EJ18 intake manifold is an ugly beast and it would be nice to swap the EJ18 wiring harness onto an EJ22 intake manifold, since those are much simpler and cleaner. but i don't know if that's possible, i have gone the opposite direction and end up with a clean EJ22 manifold anyway.

 

EJ18's don't have a knock sensor and the EJ22 will. since you're installing in an EJ18 vehicle that doesn't mean anything except you'll have an unused knock sensor in the top of the block. leave it or remove it, you can't use it.

 

the Ej18 will also have a bizarre contraption on the passengers side exhaust port in the head. there's a pipe that's bolted to a hole in the head there. the EJ22 will not have this port (well, maybe some really early one's do, but i've never seen it). so there's no place to install this EJ18 contraption. there does not appear to be any sensors associated with it (like the EGR has) so it seems like you can just remove it. i've removed it on my swaps and block that EJ18 port off, but i'm going the opposite way and an EJ22/EJ25 vehicle doesnt' have this set up anyway, so it's a no brainer.

check out my notes above, that's not always the case. easily interchangeable with very simple issues though.
