January 3, 201016 yr My 2005 2.5xt motor blew a turbo and needs replacing. Can the motor be swapped for an H6 motor? Can it be swapped for a WRX STI motor? Will the wiring harness be the same? The mounts to the automatic transmission? Are there any used motors available? I live in northern Alberta.
January 3, 201016 yr I think the STi motor swap would be real doable. They are very close. But to go with an H6, it would be quite a bit of work with wiring
January 4, 201016 yr you can't swap 6 cylinder and 4 cylinder motors without significant wiring harness issues and actually more issues than that. you'll wan to stick with 4 cylinder stuff if wiring/full on custom stuff isn't your gig. turbo's are good for a lot of horsepower, i'd just plan on getting another block. "blew a turbo and needs a new engine"? are you sure the motor is toast?

January 4, 201016 yr ^agreed. it's not a simple swap, but it's doable. motor mounts and engine bellhousing is the same. so mechanically it's fairly simple as long as it's an EZ H6 (2000+). the EG33 (SVXs) is much longer, and will require moving of the radiator. wiring is not simple. a standard EZ30D (2000-2004) isn't too bad. not plug and play, but as far as subaru swaps go, it's not too bad. Still have to pull the whole bulkhead harness out of the donor, strip out the unnecessary, pull the dash in the other car, splice in the new engine harness, put the dash back, and go. EZ30DR/36DRs (2005+) have immobilizers. which make using the stock ECU in a swap nearly impossible. only way to do it is to swap EVERY electrical control box/sensor in the whole car. which isn't really possible unless it's into another outback/tribeca of the same body style. So you're left using a standalone control system. Hydra and Link will control them. Hydra using closed-loop AVCS control, but the Link G4 can run the AVCS in open-loop mode. Both would be a much simpler control than stock, so making a harness wouldn't be difficult.
January 4, 201016 yr What other issues?the one i was thinking of:EZ30DR/36DRs (2005+) have immobilizers. which make using the stock ECU in a swap nearly impossible.
January 4, 201016 yr Right, not like you to hold back information...i thought this seem very pointed. seemed to me he wondering if this was plug and play or not and specifics didn't matter. this discussion on the electronics has already happened on the XT boards (phil swapped one in his XT6) and it's been mentioned on the subaruoutback.org forum as well.
