I need to swap out my 2.5 5-sp. with a 2.2 auto motor. wondering if i can use the same ecu, flywheel, exhaust ect... anything else i should consider or be prepared for? I guess i'm wondering if this is a pretty straight swap? and where can i find out how to read the 2.2 engine code to see what year it's out of. it's (584116583045) Thanks for everything!

You can compare part numbers for the clutch and flywheel parts here... http://opposedforces.com/parts/

Use the flywheel from the 2.5 (it's the only one you have anyways).

depending on the year of the 2.2 motor, you may need the exhaust manifold, y-pipe. some are single port and some a double.

 

if you have the 2.2 car, use the power steering lines. the ones from the 2.5 car will work, but the 2.2 ones a little cleaner.

 

you have to use the 2.5 flywheel, it matches the the trans.

 

there may be a chance that the GT alternator has more amps , but either should work. (actually that may only be the outback, maybe)

 

leave the AC compressor attached to the hoses , just unbolt it from the engine and flop it out of the way. this will save on re-charging the system and polluting.

 

the egr system is a stumbling point for some of these swaps, but your 2.2 either has it or it doesn't.

 

do some searching and read up on it.

 

good luck

they have/had atleast 2 threads going about this swap.

 

So the exhaust and stuff I had mentioned in that thread - the thread where they have the engine serial# and want to know what your it is.

 

I believe some searching and reading is in order by the poster rather than starting mulitple threads asking common questions. But that's me. Just giving others a heads up. Several of us answering the same common questions deosn't make any sense to me. Especially when searching would have easily turned up the info to begin with.
