Could it be done? Drop-in fit or would there need to be a lot of adjustments necessary? Just wondering since Forester is based on Impreza platform. For instance say if a guy had a connection in a fairly large auto salvage operation and if a WRX were to come in to their yard as salvage from a total loss accident where the engine bay took no or minimal damage and he could get a deal on the mangled WRX's undamaged engine and ECU etc... Just dreaming here.
First thing that came to mind would be is it worth the time and money for 40hp? I am NOT a tuner but I would have thought there would have been cheaper ways to boost your numbers while keeping the warranty somewhat intact.
I believe the bump in power vs. the '09 came from the different turbo and exhaust. Swapping the whole engine is pretty extreme, the difference in compression ratio (8.2:1 in the WRX vs. 8.4:1 in the FXT) isn't THAT huge and you could lower it by just installing lower-compression pistons. I'd go forged since they'd be lighter, too.
Better-flowing downpipe and a slightly bigger turbo and you'll be over that figure easily. That number is measured at the crank, dyno figures most of us use here are at the wheels (~35% difference?).
Putting a turbo engine in a non-turbo car can be done, but there are some issues (cross-member in the way of downpipe?)
unless you can get a crazy deal and do the labor yourself I personally wouldn't bother unless it's an STi engine. But that's just me. Pretty sure Sea-Scooby is right though. It should take much to get the SH up to, or past, the power of the WRX.
If you can get all of the wiring and transmission parts too... then go for it!
You'd have one of the first 5-speed FXT's in North America then, if not the first. There's at least one 6-speed already, but not sure about the 5.

Remember that you'd need a new FXT hood though.
true enough , but of course anything can be done, just a matter of time and money.
