It has been done. This is not a new formula. I was steered towards the formula by more than one veteran tuner and master tech that first did this years ago. Single port or dual port doesn't really matter. JUST DO IT

So far my best source of Short blocks is from CCRengines at $1150 + shipping

Where do people who do swaps sell their RS engines ?

Mating between EJ25 short block and L-4EAT auto-transmission?

One of the salespeople at CCRengines said that swapping in the EJ25 short block to a EJ22 Automatic transmission could be a problem, since apparently
one of them has 4 screws and the other has 8 screw openings and they may not mate up

I think all off the Phase II engines 2.2 and 2.5 use the extra screws. But then, they are the experts

Well, FWIW, last week I swapped a working EJ25 from a non-working EJ25 Legacy Outback. It had 4 bolts but it was a manual transmission. Either way, the 4 vs. 8 bolts shouldn't matter - I know of a few people running L or RS tranny's (4 bolts AFAIK) mated to WRX EJ20 blocks (8 bolts) without issue.

Here in the private classifieds.

And if you do a search, you will find the 4 bolt vs 8 bolt thing was addressed years ago. 4 bolts is fine...

Matt , on your hybrids have you had to upgrade the EJ22 fuel pumps and fuel injectors ?
have you had to add knock sensors like MSD or J&S Ultra Safeguard ?

Fuel Pumps and Fuel Injectors may need to be upgrading when going from a 2.2L
to a EJ25 Hybrid, since there is risk of knock due to fuel starvation, when hp is grossly increased from stock

Would instead adding a J&S Ultrasafeguard knock sensor prevent knock and let us get by on stock fuel pumps and fuel injectors and perhaps even use lower Octane

I would never trust a 2.2 fuel pump in any performance arena. They tend to become unreliable garbage after years of use. Many people have problems with their fuel systems completly due to their old fuel pumps.

So what fuel pump do you recommend
I remember that you posted that the Walbro 255 caused gas mileage to drop a lot

But the fuel pressure regulator still comes after the fuel pump

do you just have to get higher compression ratio piston head to increase the compression ratio?? cause it seems too good to be true if thats it.... it seems to simple. Does anybody recommend to switch the fuel injectors? if you have a full intake/ exhaust system with a pulley kit?

Vincent,
Many of the guys in this discussion have cars that are 5 to 10 years newer than yours. And your SC'd fuel needs are much higher than us NA guys. Don't scare them with your talk. This thread has already had some of the same questions asked 2 or 3 times. We don't need to dip into fuel pump paranoia. Dizzy's car is running a stock 1.8l fuel pump with 214k mi on it on his EJ25/22 hybrid. We have contemplated dropping in a WRX or Legacy Turbo pump, but have only heard the car detonate once since we put it together. It drives like a beast and gets terrible gas mileage. I repeat, run the numbers guys, do the math. The stock injectors will be fine for 200chp...

OK - so I tried PM'ing Matt Monson, but I imagine he's as busy as all get out, so I'll pose my questions here for anybody willing to take a shot at them:

I plan on starting to acquire parts for the EJ22 heads + EJ25 block on my g/f's 1997 impreza wagon. It has about 150,000 miles on the clock which is "barely broken in," but I want to have a replacement motor ready to drop in for the day it finally decides to let go.

My first few questions are related to parts so I know what I should start looking for. I'm a mechanic, and by no means and engine builder, but I don't mind doing the legwork and research, acquire the parts and then give them to somebody to build for me.

1. What block should you go with? EJ25 Phase I or II?

2. Any prep work required on the block at all?

3. What head gasket should one use? (Brand and thickness)

4. What heads should one use? (Phase ?, Model Year?)

5. What is the target or believed final CR (if anybody has computed it)

6. What gas should you run? (93 and up octane?)

7. What other supporting modifications should be done at the same time? (Cams? Fuel injectors? Fuel pump? Spark Plugs?)

8. What ECU can handle this frankenstein setup? (Stock EJ22 ECU?) Is anybody planning on using any aftermarket engine management?

9. Did you have to make any wiring modifications? (Are all the sensors the EJ22 requires plug and play to the sensors on the EJ25 block?) Are any sensors left over? Any unused sensors or holes?

10. Gas mileage has been reported to drop significantly - how much has it dropped?

I don't know enough about the EJ25/EJ22 block/head setup to really offer any concrete advice. I'm pretty sure the compression ratio would go thru the roof with the 2.2 heads. If anything you'd want the EJ22T heads.

Others will know more and be able to guide you better.

D'oh! I'm sorry, I thought you had this setup in your car- I must be confusing you with somebody else. Thanks for chiming in though!
