Here is a chart showing the latest US market Subaru engines that you can install. For installation in our shop, we can use 2.5L engines up to 2012 for some models. Please click on the Small Car info pages for each engine type to view details and pricing.
For the model years highlighted in green we can modify the Subaru wire harness or provide a do-it-yourself kit for the modifications. The yellow highlighted models require special modifications to the wiring and ECM that we are able to provide when the harness is modified here. Please see our Harness Modification page. For those models highlighted in orange, a Small Car provided harness and ECM must be used. For the model years with a white background we are not currently able to offer a harness conversion.
