Trent Posted March 26, 2015 Share Posted March 26, 2015 I have an 07 legacy with a 2.5 no turbo and I want to know if it is possible to swap the motor for something better or newer. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted March 26, 2015 Share Posted March 26, 2015 (edited) possible with enough $$$$. Could easily involve some or all of the following (in ADDITION to the engine); transmission, wiring harness, ECU, rear differential.

Trent Posted March 26, 2015 Author Share Posted March 26, 2015 Doesn't sound worth it. I only paid 3600 for the car. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted March 26, 2015 Share Posted March 26, 2015 (edited) best ways to make the car more 'fun' involve reducing mass and stiffening suspension so you can throw it around corners. Lots of mods/parts to help with that. Otherwise, sell it and shop for a WRX. Edited March 26, 2015 by 1 Lucky Texan Link to comment Share on other sites More sharing options...
Trent Posted March 26, 2015 Author Share Posted March 26, 2015 The reason I ask is because the motor needs rebuild or replace. If I can find a motor then I won't rebuild, and if there are multiple motors that would fit it increases my chances. I love the car buy I don't want a money pit Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted March 26, 2015 Share Posted March 26, 2015 (edited) maybe look at engine prices on car-part.com probably need to at least do a timing belt service on any used engine. what happened to the engine?

Trent Posted March 26, 2015 Author Share Posted March 26, 2015 Camshaft bearings are making noise. I think the previous owner drove it hard. so a 2006-2007 2.5 is all that would easily fit? Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted March 26, 2015 Share Posted March 26, 2015 (edited) never read of that issue before.others here will be better able to advise you - just make sure you need an engine before proceeding. If the issue is 'only' in the heads (no overheating, oil starvation, etc. that would affect the other internals) - you could get used/rebuilt heads put on, with MLS gaskets, and perhaps have a more reliable engine than an entire used engine.

ccrinc Posted March 26, 2015 Share Posted March 26, 2015 There is no such thing in a Subaru engine as a "camshaft bearing". What kind of noise are you getting and can you pin down from what of the engine it's coming? Link to comment Share on other sites More sharing options...
Trent Posted March 26, 2015 Author Share Posted March 26, 2015 Oh really?! Maybe crankshaft bearings? Ticking sound from motor when applying consistent pressure on throttle. Sound goes away when accelerating or decelerating Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted March 27, 2015 Share Posted March 27, 2015 you need to fins a good mechanic. Could be just a little piston slap or a timing belt moving around or ??? how many miles on the car? we have a few Canadians on the board but, dunno if any of them are in your area - still, start a new thread asking for a mechanic near your city.

ccrinc Posted March 27, 2015 Share Posted March 27, 2015 1) To answer your first question, the choices of engine for your car are limited, unless you would want to do an entire swap, which it is obvious you don't. Therefore, you must either find an engine which matches your engine (between 2006-2009). If you have AVCS or VVT, it must match those. Also, the PCV hole in the top of the block, crank sprocket, left cam sprocket, EGR, and number of exhaust ports must match. The crank sprocket and left cam sprocket can be swapped: the other stuff...not so much. 2) Diagnosing the kind of noise you describe is nearly impossible without tearing into the engine. There are so many things which can cause it. So, without going into that any more, yeah...you need a new engine. Link to comment Share on other sites More sharing options...

Or it could be slight piston slap which may pose no real imminent problem depending on severity. Described as "ticking". Much more likely to be piston slap than if it was a knocking. To the OP. I would have the oil screen at the pressure valves on each head cleaned/replaced. Could just be vale train noise from lack of pressure to the AVCS( one intake valve per cyl has variable lift activated by oil pressure) Edited March 27, 2015 by Gloyale Link to comment Share on other sites More sharing options...

Could just be vale train noise from lack of pressure to the AVCS( one intake valve per cyl has variable lift activated by oil pressure) That's the problem: we don't know if it actually is a piston slap noise (which generally goes away when the engine has warmed up), unless it's gotten bad enough to damage the cylinder walls. Nor do we know if it is AVCS or VVT. It could be a cracked ring land, a cracked flex plate (if it's an automatic), loose wrist pin...the list goes on. It is also possible that a valve adjust could solve the problem. I'm just saying that it is all conjecture at this point. Every action at this point, without knowing, is just throwing money at it.

Trent Posted March 31, 2015 Author Share Posted March 31, 2015 Are there any other motors that would fit in the 07 legacy? Link to comment Share on other sites More sharing options...
