Cool Ej22t vs ej22 n/a pistons

So i have an ej22t that broke some ring lands so i pulled the pistons out and i have a ej22 n/a block siting around i was wondering if the pistons are the same like interchangeable?? like i know they will fit because there both ej 2.2L engines however are they the same pistons or not?

Not the same. The 2.2 N/A had higher compression. Stock is 8:1 I think that will bump you to somewhere around 9:1

Not the same but a good option if you are switching to DOHC heads...

Unhappy

Ok so it looks like ill drop in some n/a pistons than and get that 9:1 compression however i am planning on installing a wrx turbo and inter cooler onto this engine as well and Im going to be using the ej22t heads with it will i have any problems with this higher compression ratio?

Also now that i have the block down this far and it has over 200k origenal miles on it and it ran out of oil for apx 5 seconds w/ 2 busted ringlands im thinking of spliting the block and inspecting components and replacing all the bearings main and rod bearings so im wondering is there a tork spec for mainand rod bearings and should i use plastic gauge or is there a special way of installing new bearings? or can i just replace them and trok them down or what thank you.

IIRC, the EJ22T heads have the same comb. chamber volume as the N/A heads.

So if you throw in N/A EJ22 pistons into an EJ22T block, you get the stock 9.7:1 compression ratio. Stock EJ22T piston dish is 28cc's, 12cc's for the N/A pistons.

Once you look at the condition of the block, and see the damage, you will be able to make an informed descision on what to do next. You have to torque the block down a certain way. It isnt hard, basically start in the middle, and work your way out. I have the specs in my chiltons manual. But of course, I dont have it within 20 miles of me.

New EJ22T pistons can be bought for around $400 from Weisco and they are forged. Being that you are going to be running boost, I wouldnt cheap out or you will be doing this build again in the future. Just get the forged pistopns and be done with it. Do it right the first time, or youll be doing it again later IMO.

Has anyone seen EJ22 forged pistons (high compression)?? those paired with an EJ22T block / 205 WRX heads would keep the compression up a little higher- be just about right for E85 Some good rods etc.... hmmm....

Ron at Raw Performance (formerly of Axis Power) has built a bunch of Ej22T bottom ends with custome pistons mated to Ej205 heads. Because core Ej22T's aren't readily available anymore he doesn't list Ej22 parts on his website, but if you contact him, I am sure he can still get the pistons. IIRC, they were made by Wiseco and you may also be able to order them directly from them...

I'm sure that Ron can offer you a set of custom made CP pistons for this application.

It makes me chuckle when someone is trying to put together a custom engine configuration and they aren't able to do the most basic engine builder's math of computing a compression ratio.

I have noticed that there are a lot of pricks on this site. Just because you have a lot of experience doesn't give you the right to be a jerk. People want to learn about subarus and its people like the ones on this site that give subaru owners a bad name. People come here for answers. Not to get made fun of. Thanks for being a prick leftho0k. Much appreciated!

Cool story bro. I've just dumped 20H heads on an n/a 22E. I didn't go crying for help. I researched the **** out of it.
