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.
Phase 1 - 1998 and older
Phase 2 without AVLS - 1999-2005
Phase 2 with AVLS and 2 wire Camshaft position sensor
2006-2011 Impreza and Legacy
2006-2010 for Forester
2012+ non turbo Legacy, Impreza, and Crosstrek
2011+ non turbo Forester
If you're interested in a turbo swap, here are some good options:
2002-2005 USDM WRX (EJ205 without AVCS)
2006-2014 USDM WRX (EJ255)
2004-2007 USDM STi (EJ257)
2001-2006 JDM WRX (EJ205 with AVCS)
2001-2006 JDM STi (EJ207 with AVCS)
2008+ STi (Coming Soon)
