Exclamation 95 1.8 to 98 2.2 swap

Hello to all,

I have not posted in awhile but the last time, it was quite helpful. I just completed a swap from a '98 impreza 2.2 into my faithful red steed, a '95 impreza outback. Well, needless to say, I need some help...all went okay except the wiring; I ended up using the old harness (1.8) since the blocks from the firewall were compatable, but when it came the emissions and other wiring, I was at a loss . I took it to a local garage and the guy tells me; "it can't be done, that I need to replace it with the exact motor that it came with" ; now I know from reading the forums that, this probably is not true. So, now, I am towing it back home and hopefully, not covering it up until next spring and then pulling the 2.2 and trying to sell it or worst yet, retiring my faithful Outback . I need an expert with some wiring help or any other help to get my steed going. Thanks in advance

Take the emissions sensors off the old motor and put them on the new motor. Use the same plugs with the same sensors.

PM me with specifics or email me pictures. It can be done......

First of all, stay away from that local garage if you were given that information by anyone but the oil change bitch. That person obviously doesn't have any understanding of electricity.

I swapped a 1997 2.2L in place of the 1.8L in my 1995 Impreza. No wiring was necessary.

Swap the 2.2 block and heads, reusing the 1.8L intake manifold, fuel system, wiring, etc. It's a cakewalk, I did mine on a Saturday afternoon.
