Discontinued Services

We no longer support these platforms due to the difficulties associated with finding the necessary OEM parts to get the swap completed and maintained as well as lack of available tuning options (non OBD2) and parts for upgrading them.

We would not recommend this swap due to compatibility issues. Please reference this post for more details on engines that would be better options to work with your model.

Thank you for your interest in our wiring harnesses. Unfortunately, we no longer create custom harnesses for this type of project

Engine blow up?

For non turbo engines it would be best to stick to an engine with similar features. For example a 2000 Impreza engine would not be good in a 95 chassis because phase 2 engines are not compatible with phase 1 wiring. Another scenario would be a 2007 NA engine in a 2005 RS would create an issue because the 2005 RS ECU is not able to control the AVLS on the 2007 engine.
