Default Limits of the stock ej22t shortblock

Hi i was just wondering what the stock internals of the ej22t can handle

For example i am thinking of taking a ej22t shortblock and putting wrx heads on it and merging that with my current 2004rs ecu.

I would plan on running a td04 and id like to have maybe 13lbs of boost (aka) wrx equivalent with more midrange and not as horrible turbo lag and low end.

So can a stock 2.2t shortblock take this? *by this i mean pistons/ rods/ crank

But not only that, how risky is this (should i expect failures in the near future?)

there are guys that have run 30+psi on BIG turbos on that motor...it will EASILY make 400+hp

what you plan is the purest waste of all involved of a nice 22t

dont **** up a nice motor doing dumb things to it

oh lol i dont plan on staying that way forever (and i know it is the high hp /high boost engine of choice) thats why im considering it, because in the future i plan on fully building it.

I was wondering what the STOCK pistons/ rods/ crank can take power wise and boost wise.

All of the people running 30psi have forged pistons better rods and a better crank.

I want to keep it at wrx power levels for a little while until i can save up the money for forged pistons rods and a better crank plus the turbo needed to make that power as well as a front mount/ injectors/ fuel pump /transmission /clutch setup ect....

I have heard that the stock pistons can take up to 14lbs of boost but i'm not really sure and that's why i was asking here among the gurus.

EJ22T has a problem with cooling, I believe.

Yes, you would be fine at that power level.

These engines are 20 years old now, keep that in mind, it could have significant wear.

In stock form:

EJ22T has the same crank and rods as the early EJ20G. Rods are the limiter in stock form, as on the EJ20G. The pistons are cast, and of the same basic design as the EJ20Gs - so power limits on those are also the basically the same.

Watch the compression ratio and quench, as the EJ22T pistons stick out of the deck a few thousands.

No they don't. Its a misconception. They cool fine. I ran an EJ22T block in my road race STi without any problems. And that was on a much bigger turbo than a TD04!

Some idiot on the internet looked at the deck and said, "Damn, the closed deck is going to restrict coolant flow to the cylinder head." Not realizing that it has to flow through a head gasket that looks like this, no matter what the deck looks like:

Listen to rallycoltturbo. He's right about the rods. They are good to about 350chp, and then they start to have issues.

Listen to eastcoastbumps about the cooling issues, or more to the point the fact that there are none...

as far as i know 2.2 r the engine to go with if u want reliable power. im curently in process of building an engine. i will use early sti heads to it. and perryn turbo about 20psi. some of those 2.2 have oil sprayers inside which is big+

On a high revving Subaru engine it is more important to keep your rod bearings well lubricated than it is to keep your pistons just that little bit cooler. I recommend plugging the oil squirters.

Really? i would think that the oil squirters would be one of the big bonuses of the engine .....also i dont plan on raising the redline or anything like that

You need the oil pressure to keep the rod bearings oiled way more than any cooling effect the squirters might have.

They are usually clogged or fall out on high mileage EJ22Ts anyway.

I had mine cleaned. The stock oil pump will make enough pressure to make sure everything gets the propper lube..unless we are talking about crazy high revs

Pull the oil pan before installing the motor.. The OE oil squirters tend to pop out...

Im running a 91 Legacy tubro ( Came stock EJ22T )

The EJ22T Block Amazing.
the EJ22T Heads BLOW
Interals are okay ( crazy power = buying forged internals )


Buying some EJ20G/K heads will help you
They will also give you more options on your intake manifold ( so you can run under intake inlet more turbo options without modifications )


Overall EJ22T is a very nice setup only most old schoolers know about! do some more research! A stock Ej22T with suporting mods and aftermarket tuning ( Such as robs tune ) will get you about 250-275 WHP on stock internals with the crappy EJ22T heads running about 19PSI on a TD05H. ( you wont get much more out of the EJ22T heads ) Thats of course if the engine is in good shape and not beat to hell lol

Ya from the old turbo legacys from the early 90's. They have oil squirters among other things. SOHC

As many have said. Rods will be the weakest part. Around 350-400 BHP is the upper limit since they are a lot narrower than the later rods. Pistons are cast but are OKish upto 400 BHP. Cranks have the thrust bearing on #3 journal which is a PITA when trying to find a new crank or you can have the block machined to accept later #5 journal cranks. The block itself is great and can handle LOTS!

if your gonna do it I highly recomend doing a dohc head swap before installing it. Its just easier to do it in the first place. I ran 13-15ish on the motor for two years before the age of the motor spun a bearing. now running 20 psi on a rebuild for about 9 months now. very reliable and drivable with the dohc. powerband is just way to early and short with the sohc.
