EJ22 vs. EJ22E vs. EJ22G, Any Difference?

[91LegLS]

Are there any differences between these engines? Are there different generations of the EJ22?

The EJ22G is the engine that came in the limited production 22B Impreza WRX, so it is a DOHC Turbocharged engine, an EJ22 is a SOHC N/A engine, I'm not sure what an EJ22E is. So yes, they are different.

EJ22 and EJ22E are the same. EJ22T is the USDM Turbo engine that came in 91-94 Legacies (Sport Sedan or Touring Wagon).

Thanks for letting us know about the EJ22 and the EJ22E, and you are right that the EJ22T (SOHC turbocharged) was for the US model Legacy Turbo, but that wasn't one of the engines models he was asking about.

EJ22 used in the Legacy/Outback.

 

EJ22E used in the Impreza. Slight change to the pistons.

 

EJ22G as described, bored out for limited production in the WRX ( about 450 world wide was the number I remember ). Don't remember what countries it was sold in as the WRX's I have seen have been the 2.0L.

Sorry, but I'm going to have to once again say that EJ22 = EJ22E. Everyone just forgets the E part.

 

Picture is taken from my 1991 Legacy:

Sorry, but it isn't a bored out 2.0, it has it's own special block, and unlike the EJ22T, it doesn't not have the oil sprayers to cool the pistons. A better description of the engine might be an EJ22 block, with low compression turbo pistons and DOHC heads similar to the EJ20G. Like I stated, the limited production was called the 22B, it was available in all countries that have right hand drive vehicles.

EJ22 = just the first 4-digits

EJ22E = all USDM N/A 2.2-liter engines from 90-96

EJ22EZ = all USDM 2.2-liter engines from 97-98 (9.7:1 CR, solid lifters, single-port exhaust, but still Phase I)

EJ222/EJ223 = USDM 2.2-liter engines from 99-01 (same stuff as EZ, but Phase II)

 

There's some weirdness in the transition from E to EZ in 96, as some 96 2.2 owners report having solid lifters and single-port exhaust.

 

EJ22T = 91-94 USDM Legacy Turbo engine

EJ22G = Impreza 22B engine

 

EJ22T is NOT the same as EJ22G, despite what the Nasioc clowns tell you.

i have a 1994 legacy wagon the original paper work on this car says ej22g.  it is OHV & non turbo 2.2L   so ???? not sure how that works or fits in

[forester2002s]

Does the car still have the original engine?

There were two possible legacy engines in 1994.  Non turbo and turbo EJ22. run the VIN and it’ll tell you. One of the numbers in the VIN tells you if it was originally turbo or not.  

are you positive the original paper is actually the original for that exact car? And how do you know it says EJ22G?

It would be no surprise to blow a turbo motor and install a much cheaper and easier to find non turbo EJ22 particularly on those older models with simplistic electronics  

All 1990-1998 EJ22s are interchangeable with effort, in spite of a few differences. 

Electronics change in 1995 despite it retaining the dual port exhaust of 90-94 models. 

turbos were available 1990-1994. There were no turbo engine available in US market 95-98 legacy.

Please post a pic of the 'original paperwork' (block out any personal info). Also a pic of the VIN/chassis tag by the USA/Canada driver's side (LEFT) front strut tower. Here:

Hi folks,  have  2003 Baja, car is in magnificent shadow for the year,  142k miles, US model but out of Saskatoon, EJ21 engine I believe,  burning a little oil, thinking of either rebuild or install a donor one.  

Looking for thoughts on costs of rebuild or buy a donor,  see costs are quite reasonable for donor units. 

I assume al the mounts are pretty much identical. I dont want any less power but also no looking to go turbo although they are fun! Had an '06 Legacy GT.
