Default EJ22 vs STI engine

I'm a newbie lookin to get into subarus. My tentative plan is to buy an early 90's two door coupe, and swap in an STI engine, but i have heard that the EJ22 engine has a closed deck block and can handle up to around 40 pounds of boost. Is this true, and if so what would be able to give me more power and an easier swap? thanks

i dont know about your boost quesiton but i do know that most often the engines you speek of (2.2L) were rated at 276 hp, as opposed to 300hp from the USDM STi engine.

the ej22 has been know to handle 30psi, from a junkyard block with 100k on it. That said.

If you just want to slap a short block on to your heads go with the ej257 usdm sti motor, or if you like to rev high get a ej207 jdm sti motor.

If you want all the toys and have the money go to i speed or axis and get a 2.2,2.3,2.4 block with a nice redline, forged parts, closed deck.

My dream block is a 2.2 with a ver8 crank.

Price isn't a problem really> I'm lookin to get the most power into an early 90's 2 door, or possibly impreza wagon. I've also heard that for higher powered cars, audi transmissions are swapped in.Are they a better transmission, and easily put in. Thanks for all your help.

Never heard of useing an audi.... I think a 6 speed will be good for the 500-600lb tq range, other then that your in the prodrive 6speed case/5 speed gears dog box.....

what kind of power??

If you want huge power, and torque that will snap any tranny, and money isnt an option i speed makes a 2.6 and a 2.8, and axis' 2.4 is impresive, cobbs 2.5 is nice too.

first off the year you will be looking for is a 93 which it the first year for impreza in the states not really sure when they started making them in japan.

Second I also heard the the auto tranny handles more power then the manuel but your best bet would be to do alot a reshearch before you jump into anything.

With the motor,the 2.2 block out of a impreza is a semi closed block I belive you will be looking for a ej22t which will not be easy to find in a junk yard. You can buy the block from subaru for 1500. Just my .02.

Ya its not called an ej22t its just called it that here. I think the offical is name ej22g... but im not sure; as for the subaru auto holding more power then the manual. No...

And the only impreza that had a bigger then 2.0 block was the 22b in 98. This closed deck, that came out of a 90-94? legacy, isnt the same 2.2 the 22b has. The 22b does not have oil squrters.

www.subaruparts.com has the turbo legacy 2.2L blocks for 1500 and some change.

i'm not talking about the 22b. when it comes to the engine. You may be very well right about the code but I was assuming that he was talking abot the ej22t from the legacy not from the 22b.

As far as the auto I've read in sport compact car about a guy switching his wrx to auto because of the very reason of holding more power. Plus he switched it to handle higher levels of boast. Of coarse I am talking that the internals are rebulit to handle the power. Also I've read somewhere on the boards I will have to search that they are having trouble with the 6 speed tranny holding 300 lbs. of torque because they wanted to use the 6 speed in the new svx.

Here's an idea for an engine. The 2.2 closed deck block with DOHC 2.5 heads. That lowers your compression ratio to 7.5:1 and will be able to take big boost. Find the right turbo and the engine will have no problem holding the power.

As for a tranny. You'll find that you're very powerful cars usually will have an auto tranny. The Easy Street Motorsports WRX, which runs an 9.88, has an auto tranny. I'm not saying you'll get that much power, but if you plan on it, research some good auto trannies you can use for your Subaru dragster setup. To my understanding, the auto is able to take more because the torque converter in the auto can take the pounding that a lot of clutch disks can't take. I think you're probably looking for a more mild setup, so I think the Ver 8 USDM STi 6 speed might be your best route. That's because it's a fairly new tranny and the durability of it really hasn't been tested very extensively. Plus you'll get all the goodies that come with the 6 speed (DCCD).

Good luck.

Easy streets box is close to $10k and hardly stock, prodrive wont even sell the stage 3 power pack for autos because they dont belive it will hold.

There is not a impreza with the closed 2.2 other then the 22b. And its not the same as the 2.2 ej22g legacy block. The code is ej22g..... or k but im almost sure its g, I dont know what the code is for the 22b but that doesnt matter because you cant get one.

The guy in scc isnt using a stock box if I remember... as for you link it has little to do with what is out now and what is down the pipeline for cars that are not even in production.

You're right. The turbo Legacy block and the 22b block are 2 different blocks and 22b parts can only be purchased by 22b owners. The EJ22 in some of the Imprezas is an open deck engine, IIRC.

if you read my one post you would read that I said he had rebuilt internals which would handle the higher levels of boast. but in his case i do belive scoobyimrpza said it right that he will be satisfied with the 6 speed.

As for the link I posted it to point out that subaru said they were having trouble with the 6 speed gear box handling over 350 lbs of torgue.

As far as the motor that was my mistake for not saying the legacy.

Thanks for all your help guys, i appreciate it. I found a guy whose sellin a 2003 STi spec C with twin scroll turbo and intercooler, and 6speed DCCD gearbox. If i can get this i think that im going to do that. Probably put it into a '95 impreza L, if its gonna be possible for me too. Im not expert here, so if there are any huge flaws here feel free to rip me apart, i can use the input. thanks again

Front clip? or just the motor and tranny. If its not the front clip then you will need a front crossmember, search for more info. The 6 speed in to a old gc8 style car is going to need some "tunnel work" not sure what that means. I have never seen the swap completed, but I know its been covered as to what you will need.

It's been discussed that the swap can actually be done without the tunnel work.

As totoherbs said, you will need the crossmember for the engine. Hopefully the swap comes with the ECU and all the wiring also. Try to get as much as possible with the swap, so you have less additional stuff to purchase, like the rear differential.

if i'm not mistaken... the 2.2L in the Legacy Turbo and the 2.2L that showed up in Imprezas are not the same block.

Legacy 2.2T was a closed deck whereas the Impreza 2.2 was not.

I dunno, here on the interweb I develop a lot of boast very quickly!

But seriously... it seems a bit odd to me for someone who's never had a Subaru to suddenly be jumping into the middle of the crazy motor swap bandwagon like this. I mean... I know he's just fact-finding for now, but really... slow down! This sounds like a fantastic way to wind up with a half-completed project that doesn't fit together quite right

I agree with you, it is a pretty big first project, and if i was going to do it by myself then i would be starting off a lot smaller, but im getting the help of some friends who know what theyre doing and can teach me alot. Other than gettin a sweet care (hopefully) I'll be learning a lot so i can do things on my own later and give everyone else some advice.
