dp213 Posted November 8, 2014 Share Posted November 8, 2014 I have a 98 2.2 from an impreza that I want to use to replace the bad 2.5 in my 98 outback. Can it be done without a lot of hassle? Do I use the 2.2 or 2.5 intake. Link to comment Share on other sites More sharing options...
ocei77 Posted November 8, 2014 Share Posted November 8, 2014 (edited) Direct swap, no need to replace intake. You will need the Y pipe from the 2.2 to match the heads. If cars are auto, you also need to swap the 2.5 flex plate onto the 2.2 block. Replace the separator plate on rear with the updated metal one. Do search for swap and you'll get a lot more info. You can also download the fsm for future reference. If you don't know the engine history now would be a great time to do the t belt and idlers. If over 200k, do the water pump too. O.
