Question regarding the 2.5 turbo engines

[tbolt1003]

Do the turbo engines in the older Foresters and Outbacks have the same issues the WRX and STI engines have, like ringland failures, bearing failures, etc. I'm looking at a stock turbo Forester and an Outback, but don't want to deal with the failures if it's a common thing. Thanks!

Yes.  They all have oiling issues which is what causes the bearing failures.  In fact, the older ones are worse than the newer models.

 

Ringland failures are usually the fault of the owner: too aggressive on the tuning, stupid tuning, running too rich or too lean, constant redlining, etc.

 

We can hardly build these fast enough!

I would add that the Subaru stock tune is partially @ fault for the engine failures. They are tuned (too) LEAN from the factory to make EPA ratings look better @ the expense of proper fueling when in boost. For those of us that may actually 'drive' it as a performance car, this isn't to our benefit. This is documented over on NASIOC.

 

 

And as a recovering Subaru Turbo addict, I can tell you to 'just say no' to USED turbocharged Subarus. Unless your maintenance budget includes new/rebuilt blocks, heads (valves), HG ('though not as bad as the NA 2.5s), turbos, CV axles, wheel bearings......@ least the manual transmissions are usually capable (Autos are tough, but limit performance/enjoyment).

 

For about the same stock performance (but very limited upgrade options) the 3.0/3.6 H-6 engine-equipped models  are a better option over the lackluster HG-blowing 2.5 NA models. But you're stuck w/the 4/5EAT, which sux.
