I thought I would pass on to y'all a PN for thin headgaskets for the EJ22. I just picked up a set I had made through Cometic gasket in a thickness of .027" as opposed to the OEM .040". If you're looking for good gaskets and want to bump the CR a bit too, these'll fit the bill.

 

PN: C4262-040........EJ22E SOHC 16V, 98mm MLS .040" (stock)

PN: C4262-027........EJ22E SOHC 16V, 98mm MLS .027" (thin)

 

These should run about $90 for the set. Enjoy!

What does it bump the compression ratio up to?

 

Would i have to run a higher test gas?

Other thing to consider, you may have made the engine an interference engine now....

I don't know how much the CR is effected yet. It shouldn't require higher octane.

 

Post 97 EJ22s are already interference.
