Default Want to go ej22 with ej20 heads need advice

I need some help guys. Ive been looking at a bunch of threads that do a build up but none are really helping. im looking at getting an ej22 block (dont know if it needs to be the turboed version or not) and matching it up to my ej20 heads. I have heard i can run the stock internals in it as there pretty strong (dont know how much power the block can take) any help would be appreciated thank you

You really need to know about the block there is a huge differance between a turbo block and a non turbo. Find out and I'm sure people will be able to help you.

let me suggest another often replicated (tried and tested) option

ej205 wrx heads and a ej255/7 block

nothing on the 22T block makes it better than a 255/257

The only benefit you get from the EJ22 block is bigger displacement. Which means better low end power, and probably a lower rpm spool. Hell, you could just buy a Phase II EJ25 N/A block and throw that in there. If your power goals aren't sky high it will work just fine.

Are you deliberately trying to blow up this guy's car? NA Ej25 with Ej205 heads will be a compression ratio in the 11's. I don't think his WRX will run very long like that...

You can use the NA Ej22e block for what you want to do. I honestly don't know why more people don't do this. You'll have a compression ratio somewhere around 8.8:1 +/-. You'll pick up 10% more displacement and you can get those blocks in good used condition for a couple hundred bucks. Get a custom tune and wala.

People poo poo the ej22e because it must somehow be weaker or inferior because it's NA. Bah. It's the same crank and rods. Troy Matta ran one with twin cam heads and a Garret t3/t4 hybrid turbo at 1 bar of boost for YEARS! And he'd turn it up to 18psi on race nights for running the 1/4. It's a great set up. It's budget. It's replaceable. It's reliable. What more could you want?

I should have been more specific, I forgot to mention the fact that he would need new pistons, my bad.

I don't think I've ever seen a EJ22T block crack the cylinder walls like I've seen on the EJ257. Only thing I've seen fail on the EJ22T are pistons and rods. Things I've seen failed on the EJ257 are pistons, rods, AND cylinder wall.

I can tell you that my EJ22T makes wonderful torque and ALSO revs SMOOTHER than a 2.5L would.

thats because its not possible to slap on a turbo and make 400 whp with a 2.2t in stock form

there is no reason why a 22 short block is any smoother than a 25

Sorry Keith, my car is N/A, not turbo, and I have to run premium. Matt is the one that inspired me to do it...

i know it's NA! i was just pointing to the 11:1 CR while slightly amused. wondered what octane you needed for detontion issues.

not poking fun, honestly!

just get an ej22t and stroke it. its a better block because its a closed deck and the 257 is semi closed, you can boost more with the 22t

ej22e + ej22t pistons or forged

nice motor.

ej257 + ej205 heads is hard to tune apparently since the CR is kind of high...clark said on 91 its finicky.

Like Matt said, use the EJ22E block, it gets you around 8.65:1 CR,(if you use the thick 1.52mm HG (.060'') and the bore is a closer match to the EJ205's heads. Dont even worry about the open-deck thing, you would need to throw some serious boost at that motor for it to be an issue.

x2, i think most stock blocks with the right internals are good to 400whp or so

I'm glad to hear this, I was surprised to actually find any info researching. I'm considering doing this myself since I have what I need to pull it off. And honestly, compression ratio aside, there really isn't much of a difference between stock WRX pistons and the n/a ones as far as material/composition and ringland thickness. A bump in compression and more displacement should be a blast on the stock turbo. I'm still looking, but does anyone in particular sell the .060 head gasket for the ej22? Cometic I assume?

Stock OEM and ebay EJ22 HG's are 1.52mm. No need to spend huge $$$$ on Cometic gaskets.

Are these multi-layer then? It's a real pain confirming actual thickness vs correct part number. The numbers change every search.

* I thought at one point the ej22 gasket changed thickness with a certain model year, I just want to be sure I don't get the wrong one. I did dig up this:


97/98 ej22----------11044AA114
99 ej22-------------11044AA542

11044AA282 turbo

I ordered gaskets and ended up with the composite ones...are these worth a damn? I'd really prefer the mls ones. (sorry to hijack thread)

I use the '97-'98 EJ22E HG. They are 3layer multi layer steel. I use them on my Hybrid WRX swap with GREAT success! They are thick enough for the stock 22T pistons to clear. Been running ALL SUMMER with them and driving hard too.

Rod bearing went out after all this hard driving all summer long; about 10k miles worth with OEM bearings. I have a spare EJ22E block I will be rebuilding to sell with my swap.

OK, thanks.... that's what I was looking for, a little confirmation. I would imagine the 97-98 gaskets are probably the 1.52mm noted abv.

Trying to understand this:

1) EJ22 "E" block vs. the EJ22 "T" block?

2) Rex Head or name your best substitute head.


And uhhh...where exactly does the turbo part fit into the equation or are people just using the turbos connected to a Rex OR installing them onto this setup if you don't already have a turbo'd platform?


Curious why the EJ22T block isn't used vs. the EJ22E block and if it has to do with:

1) Cost difference

2) Better direct bolt on kit vs. having to deal with the venerable 2.5 heads with a 2.2 Block

3) Block is powerful enough to support the HP people are wanting to achieve?



One last thing...does anyone around here know how much Torque this setup produces AND also what the MOST torque any Subaru turbo setup has produced? Saab comes to mind when thinking about Torque since a 250WHP Saab will also put down 320-330+ Torque, whereas the same is never said about the Suby with respect to hp and torque figures respectively.

THanks All and hope I'm making sense. Midday break may have set my head off a bit
