Ezeudu Posted August 10, 2017 Share Posted August 10, 2017 I have a 1999 Impreza Outback Sport with an EJ22 whose body is in terrible shape -- it would take much more than the car is worth to fix it. The motor is in great shape, however. I found a 2010 Impreza for sale in my local area with a body in good shape, but the seller claims it needs a new engine. Before I pursue this lead any further, I would like to know if doing a motor swap across generations like this is possible, or are there too many differences between the two for this to be viable.

GeneralDisorder Posted August 10, 2017 Share Posted August 10, 2017 Yes it could likely be done. It will require tuning to eliminate all the AVLS systems and associated codes. What you would end up with would suck a$$ though. Sell the EJ22 and buy the correct motor for the 2010. You can get reman short blocks from Subaru for $2300.

AdventureSubaru Posted August 10, 2017 Share Posted August 10, 2017 Sell the 99 and use the money for a good used motor off of car-part.com - a gates or similar timing belt kit too will save hassle down the road. Quote Link to comment Share on other sites More sharing options...
Subaru Scott Posted August 10, 2017 Share Posted August 10, 2017 ...or find a good older body in Colorado or PNW. Quote Link to comment Share on other sites More sharing options...

Fairtax4me Posted August 12, 2017 Share Posted August 12, 2017 Far too many differences between those engines. For a semi-direct swap with your engine you need a 99-04ish Impreza, 2000-04 legacy, or 99-04ish Forester. 05 was when Subaru started introducing variable valve control and electronic throttle and it gets more complicated to do a swap in a vehicle made after that.

Subaru Scott Posted August 12, 2017 Share Posted August 12, 2017 Although... if there are those of us willing to swap EJs into older cars with stripped-down harnesses, is it really so preposterous to go the other way? If all the "newer, better, drive-by-wire, electronica extravaganza" in my Tribeca starts to go on my nerves, I WILL be swapping in an EG33 w/harness Personally, I think we are not far off from super-cheap standalone systems that can do whatever you want. Then we will all be laughing at what we went through in the before time! Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 12, 2017 Share Posted August 12, 2017 It's not preposterous - it's simply ignorant and a terrible idea for the value of the 10. The 2.2 phase II engine was great at being an oil consuming pig and having slightly less power than the 2.5, similar economy, and the same problems with head gaskets, etc. Unfortunately since this bore size wasn't continued there is no updated gasket to solve the HG weeping problems like there is with the 251, and there are no good sources for the rings on the 222 except the dealer at $200 a set. All this combined makes it arguably the least attractive 2000+ Subaru engine. Very low production numbers, expensive and inferior parts.... The 99 to 01 2.2 is a great engine.... for someone else.

GD You're both right. Not preposterous to do a harness strip and install. Just not with that engine. I'd go either a 2000+ EJ251/3.........OR the best engine subaru ever made, the 90-96 EJ22e Quote Link to comment Share on other sites More sharing options...
Subaru Scott Posted August 12, 2017 Share Posted August 12, 2017 Yes, I was speaking in general. Not particularly that engine-car. Quote Link to comment Share on other sites More sharing options...
