I have a 95 legacy with a good 2.2 eng. This car is an automatic. I want to put that motor in a 96 legacy brighton wagon that has a 5 speed. The exhaust ports on the heads are different; 2 hole for 95 engine; 1 hole for the 96. I know the At engine has a pressure valve?? for the Automatic and this is not on the engine that is bad. can I just swap these motors striaght up and move the exhaust Y over to the brighton? Will the ECM in the 96 recognize the 95 engine. Looking for some seasoned advice, thanks!
