EJ22T info

what are you looking for...whole engine swaps or EJ22 short block swap?
I swaped the whole motor into my car (was a 1.8L). I got the motor, crossmember, and ecu/wiring harness for about $1000. Everything bolts up fine, the only issue was the wiring. We ended up using my stock wiring and had to change some connections to match all of it. My CEL is on, but the error is "idle control valve", that's it. It runs rich, but a Wolf 3D or a Tech II will cure the ECU confusion this summer.
anything else you would like to know?

Why bother? The pistons and rods are week in the EJ22. The only benefits are the oil squirters and closed deck. The power loss to a turboed EJ25 is huge. I've been in an 18psi EJ22 and a 10psi ej25, the bigger block was way faster.
that may be so, but how many blown 2.2's have you heard about? I can think of atleast 4 blown 2.5's... :boxer:scoobyrs25 said:
Dan Evander's 2.2 blew. (built by B-spec, or B-suck) The 2.5s blow due to bad tuning, just like Dan's 2.2. Nobody has blown a block due to it being open deck.

your point was that the pistons and rod were weak in the 2.2...not the type of deck.
I have a friend running 13psi in his Legacy w/no IC and no problems, sounds strong to me. My point is the EJ22T was a purpose built turbo motor...and I didn't have a 2.5 in the first place.
you can debate the engine size all day, but remember...

I'm not saying it is a bad motor. All I'm saying is that it is not the holy grail, and does not offer the most power. For anyone with a 1.8 or 2.0, it is an excellent choice.

How do you figure the pistons and rods are weak? How do they compare to stock 2.5L pistons and rods?scoobyrs25 said:
As for the faster ej25, is it really faster, or does it just feel faster due to the torque differences or different suspension setups.
Also, a boosted ej22 will have more hp and less torque so it might help avoid broken gear boxes.

Both engines suck ass to turbo. EJ22T is definetly capable of more horsepower out of the box. THe pistons are stronger on the EJ22T. I broke a EJ25 piston at 4psi and have yet to break an EJ22T piston at 10psi and no engine management.

The ej22 does not have forged pistons or rods. I guess weak was a bad word to use. What I should have said was that there is no advantage using the ej22 over the ej25 when talking about strength of pistons and rods. A boosted ej22 will not have more horsepower than and ej25. A smaller displacement does not equal more horsepower. More torque with equal horsepower is indeed faster. Guys! the only two special things about the ej22 short block are the oil squirters and the closed deck. You can have both of those mods done to the ej25 and have more ultimate power! In case you think I am talking out of my ass, I have indeed held in my hands a bent ej22 rod and a fried ej22 piston. They are in no way superior.

Eric, your motor's days are numbered. Get some control of your timing or buy yet another motor.

Actually It's been broke for abouta month so you are right.scoobyrs25 said:
However I must argue that the closed deck and oil squirters are not hte only advantage. One other nice advantage is the Rod-to-stroke ratio of the EJ22T. It is much better suited to high horsepower higher revving turbo motors.

you need to do some research... what years were your rod and piston that were fried... there have been some changes to the block of the EJ22T by subaru...
Also your comparison means nothing... about a 18psi EJ22t and an EJ25... at 10 psi... what were the setups and what were the turbos etc.. I have the SOHC EJ25 heads and EJ22T block with a T-28 and WRX intercooler... 13.7 at 3600 ft. (non corrected) with 5psi in 1st gear no one yet has presented a much faster car than mine WITH EJ25 stock internals... i use the stock EJ22t internals...
i have an EBC now... much much faster...
if you say nothing is forged on the EJ22T read this...

It was a brand new ej22 shortblock ordered from Subaru. From the thread you directed me to, it sounds like you guys still don't know what is and isn't forged. All I know is I held a nuked ej22 piston and a rod with a 45 degree bend in it from the brand new short block. Instead of lowering your power by going to a smaller displacement, spend the same money in forged rods and pistons for your big block! That is all I am saying. I'm not ripping on the ej22. I just don't see any real value to it over the 2.5.

forged anything will break just the same as cast... forge does not mean will not break and bulletproof does not mean will not break... if it was bent... maybe the EJ25 would have actually BROKE! and then stabbed into the side of the block... Adam Bloom has broken EJ25 rods clean off...
out of the box you can't beat the EJ22t... and some even say that this block is the 22B block... JayUK i beleive.. now if that were true subaru would pick the strongest to be in its elite car don't you think? my dealer has yet to confirm back to me what is and isn't forged in the EJ22t... but you can be certain its something...

Wow this thread took off... I'm just looking at options right now. One of the much earlier replies mentioned weak rods and pistons, but I did specify "forged rods, etc." I'm not trying for a monster engine, just something to make the drive much more fun. If it's not too much to ask, I'd like reasonable reliability as well.

All this talk about the ej22 got me confused. Are you talking about the US ej22 that is on..say..my 2.2L or the ej22T from a turbo legacy? I was thinking of supercharging my 2.2 but now I have my reservations. Please clarify. Thanx!

We have been talking about the Legacy Turbo block, it is very different indeed.
