This is a CANbus-equipped chassis which makes swapping difficult.
At this time, there are only two ways we would recommend moving forward. The first would be to take the entire harness from headlights to taillights of a similar year turbo version on your chassis (IE 08 WRX into 08 2.5i) and run a compatible engine for that platform. It would probably require a complete donor car to get all the parts you would need. The other would be to wire up a standalone ECU that can communicate with the CANbus system of the chassis and can run whichever engine you choose.
We know this sounds crazy, given we are the “Subaru Swap Guys,” but with the complexities of the project, we would suggest at least considering purchasing the turbo car you are looking to build instead of swapping.
Note: iWire is no longer wiring projects that utilize a standalone ECU.
