Default ej22t

if i plan on swapping an ej22t engine from a legacy turbo into a same year or slightly newer impreza (93-96) do i need to swap the transmission as well?

I've searched for a few days but all i find about this swap is mostly concerning sohc heads and comparisons against ej20! thanks

while i'm on the topic of my planned summer project

could someone refresh my memory as to how high the oem turbo on the legacy can boost and what hp/tq numbers i can hope to achieve? any websites and magazine articles on this topic would be helpful too!

thanks!

you don't need to change your transmission, but you will need to change the crossmember support for the motor. The EJ22 runs about 6-8psi, I believe(don't quote me), in stock form. This is good for about 160hp.

You don't have to, and its a pain in the rear to do it....

But I would reccomend it as the non-turbo gearbox is far weaker.

Sure, it will work, but the car will be a mess. FWD + Auto tranny + low compression motor = nasty drive.

You might think on buying a complete drivetrain from japan including the stuff to convert to AWD. I got a complete STi V1 setup w the entire driveline for cheap. The only part you might have to get is a fuel tank if Subaru used different ones in the FWD impreza compared to the AWD version.

what do you mean a nasty drive?? it will suck?...its possible though right?? but it wont be a good idea to run it like that for a while because AWD conversion is COSTLY...and will take up alot of work...i have been told its possible and it isnt bad at all...please follow up..thanks

The EJ22T is good for 160 hp, and 181ft/lbs of torque. The max stock boost is 8.7 psi, regulated by a less than adequate electronic boost soleniod.
Don't be fooled by these low output numbers, the 2.2T has a closed deck block with forged crank and rods. The pistons were cast , but coated. It has been reliable up to 300 whp (I wouldn't push it though)

At 15 psi for eight months, a fellow tech is starting to have problems with the 2nd gear synchronizer (what new ).-even the turbo tranny will need work (if you want to fly).

The AWD conversion isn't that bad, as long as you have the tools, lift, etc. The frame is built to accept AWD, but the gas tank will be a problem. You'll need a split tank, to have clearance for the driveline. The fuel level sending unit on split tanks is different, so keep that in mind. Get the complete rear end if possible, brakes, struts, lateral links, everything. This will considerably help install, so what if you have extra parts?!?!?
Also, try to get a 91 SS rear diff. It was the only year that the viscous LSD was stock. The gear ratio is 3.9:1, you MUST use a 3.9:1 tranny for this to work.
Contact me with questions and
HAPPY HUNTING ALL!!!!!!!

Default hondahunter...

so its not a good idea to swap the ej22t to a stock AUTO tranny of a 93 L?...as of for now, i am just trying to run it (ej22t) close to stock..maybe a few mods (exhaust, intake, etc)...and maybe try to work on increaing the boost..(not too much tho)..just for a better performance.....if I am just tryin to swap the ej22t to the stock tranny, the tranny should be able to handle 160 or so hps rite?....the tranny will only give up when I hit what certain amount of hps? but as for RIGHT now...i am not looking into going up to that much hps....hitting 250 hps will satisfy me...I am just looking for a daily/fun driving car....let me know..and thanks in advance

It will work, but you'll be wanting a AWD conversion before you turn around twice.

well..so i can do it rite??...anyways...i am planning on doing a tranny swap....but my main concern is swapping first...so that's why im asking on swapping engine to a stock tranny...OF COURSE AWD will be better...but its costly...something i cant do right now but WILL look forward in doing at a later time...so what problems might i come across by running the AUTO FWD tranny on the ej22t....(until i save enough money to swap to awd)??? thanks guys
