EJ2.2T bore and stroke

[SubaruAlliance]

i got this from an old post searching around.

 

EJ18 Bore 92mm Stroke 67mm

 

EJ22 Bore 96.9 Stroke 79mm

 

EJ25 Bore 99.6 Stroke 79mm

 

anyone know the bore, stroke, of EJ2.2T? I am looking around trying to get things together for a swap into my 03 baja. any help would be appreciated.

anyone know the compression ratio also?

Ej22t compression ratio is something like 8:1 or 8.5:1. Lower compression allows for greater efficiency and reliability on turbo motors.

 

Dunno about the bore and stroke. Pretty sure I've seen it somewhere around here though.

 

Whats the reason for the swap? Dead 2.5? Just want more power? Ej22T are probably the least easy to find of any EJ series engine.

the stock 2.5 is fine. just want more power. looking to build EJ2.2T with EJ2.0G heads on it. i am looking for the info on the bore and stroke so i can start looking for some aftermarket pistons. i would like to find something around the 8:1 range so i can cram the boost in. maybe something like 18PSI on cheap fuel. it's gonna be a long process, but the ultimate goal is gonna be a STI driveline swap (tranny and rear diff) build the 2.2 and shoot for 320-380 WHP. i wanna leave the exterior of the baja alone and have it sleeper status.

 

i can find 2.2T engines all day for around 500-600 from early 90's legacy.

maybe something like 18PSI on cheap fuel

That's a dangerous game. No way I'd run anything other than Premium gas in a F/I engine. Especially at high boost levels. Good tuning can only do so much to prevent pre-ignition. The fuel makes the difference between safe and destroyed.

 

Car-part.com is well known around these parts. Excellent resource for parts for any make of car. Thanks for posting the link for others to find.

An EJ22 is an EJ22: bore and stroke are all the same.

appreciate it guys. yeah the whole 18psi on cheap fuel thing, i am all about low compression, whereas some guys may stay in 8.5-8.8:1 i would love to find some 7:1 pistons but that will never happen. anyways i appreciate the info.

Don't need pistons, just get a really thick head gasket. There's more than one way to lose compression. You could play around with different lengths of rods, different crankshaft diameters. There are some nifty compression ratio calculators online. More than one was linked in the big Frankenmotor thread on NASIOC. Of course those guys were trying to get higher compression, so if you do the opposite of them you can probably get pretty darn low.
