Merge Services - 2001-2006 JDM/EDM V7-9
This engine is plug and play with your 2002-2005 WRX!
To get the most out of your new engine you'll want to add in the AVCS. To do this purchase our AVCS bulkhead kit, plug in your matching JDM ECU, and tune for the fuel you want to give it.

This would not be a good option for your Drive by Wire Turbo application.
There are more compatible engines that can be modified to be plug and play with your application. Please take a look at this post to find that engine
We apologize for the inconvenience and thank you again for your interest in using iWire.
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 that you are looking to build instead of swapping.
Note: iWire is no longer wiring projects that utilize a standalone ECU.

Yes! This is a swap that we support.
We're here to help but have a few steps before you send us any harnesses to ensure everything goes smoothly.

- Pull the bulkhead harness from your car where the new engine is going into and send us a picture of the bulkhead harness
- Send a picture of the bulkhead and front harnesses along with ECU and fuel pump controller (if applicable) that goes with the new engine
- Pull the bulkhead harness from your car where the new engine is going into and send us a picture.
What do I need to send?
The most common question asked is, what do I need to send? Unlike other car makers, Subaru integrates the wiring for the engine and ECU with the rest of the harness for the body of the car. There is not a plug that separates the ECU to engine wiring from everything else.

Bulkhead harness from merged vehicle. The bulkhead harness is the part underneath the dash inside the cabin that runs along the firewall from door to door. It also includes the wiring that goes into the engine bay via the 2 grommets on the passenger’s side. The bulkhead harness will disconnect from the rear harness on the passenger’s side either at the front door (01 and older) or under the passenger’s side front seat (02+).

For JDM applications we no longer merge them with the RHD harness due to fitment and quality issues we've seen recently.
Instead we offer our brand new 2.0 WRX/STi harness that is pre-wired for AVCS.
