dp213 Posted September 12, 2016 Share Posted September 12, 2016 So I bought a 2000 outback for my son real cheap ($200). The engine is done, can't turn it by hand. I'm looking to do a cheap as possible replacement. So my question is this. Can I use the 99 2.5 block and 2.2 phase 2 heads that are sitting in my shop and make it work. The block j know is good and the heads are brand new. I know I have to change the exhaust, but will this combo work? Thanks Dp213 Link to comment Share on other sites More sharing options...
dp213 Posted September 12, 2016 Author Share Posted September 12, 2016 By the way, the 99 block was from an outback, so it was kinda the phase 1 phase 2 motor they did in 99 Link to comment Share on other sites More sharing options...
AdventureSubaru Posted September 12, 2016 Share Posted September 12, 2016 Yes. Bolt it together and drive it. I have a single port Y-pipe For $20+ shipping if you want it. Link to comment Share on other sites More sharing options...
dp213 Posted September 12, 2016 Author Share Posted September 12, 2016 Thank you. I have a couple laying around. What head gaskets? Phase 2 2.2, phase 1 2.5 Link to comment Share on other sites More sharing options...
AdventureSubaru Posted September 13, 2016 Share Posted September 13, 2016 Phase 2. Technically that 2.5 block is a phase 2 block that had phase 1 heads. 99s were an odd year. Link to comment Share on other sites More sharing options...
dp213 Posted October 5, 2016 Author Share Posted October 5, 2016 What timing belt do I use? Phase 2 2.2 belt, or phase 2 2.5 belt, or are those actually the same belts. Also will it work with the older 2 bolt tensioner? Link to comment Share on other sites More sharing options...
AdventureSubaru Posted October 6, 2016 Share Posted October 6, 2016 Same belts. And as long as you have the corresponding bracket the two bolt tensioner combo will be the same. Link to comment Share on other sites More sharing options...
dp213 Posted October 12, 2016 Author Share Posted October 12, 2016 So I got it running. Started right up and runs good, but the valves are really loud. I set the valves at .008 and .010. Is that correct, or at least close. Link to comment Share on other sites More sharing options...
dp213 Posted October 12, 2016 Author Share Posted October 12, 2016 Also the idle is a bit high. All vacuum lines look good. Is there a way to adjust the idle Link to comment Share on other sites More sharing options...
