Anyone ever tried this on a later model car? I have an '11 Outback sport and would like to drop in the STI engine when mine gives up.

Mostly my son, and I, just swapped a complete 05 STi (engine, trans, rear diff, suspension, brakes, full harness, etc) into a 02 WRX. Basically he has a 05 STi in a 02 WRX hatch.
I mean like everything except headliner and front door harnesses.

Bolting it in is one thing, getting some electrics to work is another. We had to swap some wires and bits from STi fuel tank to WRX tank, swap wiper motor, plus everything else listed.

A 2011 is a totally different animal than an 05.

A 2011 won't just bolt in. Basically the suspension is totally different, so you won't be able to use knuckles, control arms, the rear brembos, or the axles, etc.

The pure drivetrain stuff should work with minimal complications. Transmission, rear diff. Need a DCCD controller and a wheel speed sensor to drive your cluster. (MapDCCD or DCCDpro can provide both) Then you'll have to find some GD chassis axles and knuckles

The engine is going to be a struggle to get to work correctly as there's no way to run dual AVCS off the 02 ECU and the wiring isn't exactly plug and play. Also the 2011 is CANBUS so EVERYTHING is run through the ECU.

You could potentially swap to your drive by cable intake and run the engine off of the 02 ECU without AVCS, but I'm not sure if that's possible will dual AVCS cars.

your better off locating an early 04 STI for the easiest swap. The front hubs are the same, the rear hubs will need to be changed due to different splines for the R180 diff. Be sure to get the crossmember for the 6 speed. Wiring wasn't bad at all. You don't have to change the ABS or ECU and cruise and ABS still work, no abs or check engine light. You might get a p1596 if you are going from a 4eat to 6 speed and keep your 4eat ecu, but does not cause issues. I used the 4eat harness for a lot of my connections, Iwire has a nice plug harness kit for this swap, I only purchased a 3 wire VSS harness to tap into the 4eat 4 wire VSS as the STI is a 3 wire VSS set up. I do have the DCCD switches and module but decided not to install it as it is more involved and costly if you wanted the factory STI setup which means you would need the complete harness and STI cluster and ECU. I would go with DCCDPro in the future that make a nice setup and can use the sti thumbwheel and switch. Without DCCD installed, you will have a 35%F-65%R ratio. I would also suggest buying new switches such as reverse light switch on the tranny as its easier to replace while the tranny is out of the car, in the event the original is faulty, realizing after you installed everything and back out of the garage and reverse lights don't work. I suggest the same with the switches on the clutch pedal assembly as it is a PITA to do when pedals are already installed. We just got done with the swap in my sons car that had a 4eat and WOW night and day difference in performance to say the least! Not to mention him having fun driving a 6 speed vs auto! Good Luck!
