The heads go to the ECU....so what ever heads you use you need their corresponding ECU to make things go the easiest.

ej22t HG....unsure what your talking about??

Sounds like your looking at stand alone ECU tuning and some harness merging. Like AEM or Mega Squirt

Oh "HG" ...duh

For the most part the head gasket hole patterns are all the same. You can widen the holes in the gasket a bit to more accommodate the block. You should use HG to heads IMO, because the block is going to be same/same weather 2.0-2.2-2.5. The heads IMO determine the end result turbo or NA gasket.

If your looking for an easy head swap onto the 2.2 with a turbo in the mix, and dont want to do a harness swap or merge. There are few things you need to confirm:

- what year is your car and are you OBD1 or OBD2
- are you SOHC or DOHC now.....I assume SOHC since your single port
- how many cam position sensors do you have ....1 or 2

Just an FYI.... changing heads and turbo charging an NA platform is quite and undertaking.

For any real tech-y questions Id call www.metricmotorsxtreme.com they do suby sand rails and crazy turbo to head combos.

Head gaskets match the BORE. Always.

The stock EJ22T pistons protrude past the deck a few thousanths. A proper/OEM EJ22T head gasket is thicker than normal to deal with this. So, unless your going to use custom pistons, use a stock EJ22T head gasket or do lots of math to prevent piston to head contact.

Yes^ I should have explained that far better.

The HG is to the bore, I should have said the water passage holes are basically the same on the HG no matter the motor size, and can be widened to accommodate the blocks passages.

Cometic makes a thicker HG for the Turbo 2.2L

Why not use newer 2.0L heads, harness, ECU? At this point they are just as cheap as any other heads and you will have a car that runs well and is tunable.

Using the old stuff and a mish mash of NA parts will work, but it's not going to run particularly well and you won't really be able to tune it. You'll go thru a lot of hassle and won't really be saving any money.

I just have all the parts for the build i was thinking of but did not think about tuneability.. So will probably wait on it and find some wrx heads, harness and ecu... Make it worth while
