SOHC vs DOHC Impreza Engines: How to Tell Them Apart
Knowing which head configuration your Subaru uses is crucial to getting the correct motor choice for your build.
- Valve Cover Design: Single Overhead Cam (SOHC) engines feature narrower, flatter valve covers compared to bulky DOHC heads.
- Timing Belt Cover: SOHC engines utilize a much simpler, compact front timing belt cover casing.
- Naturally Aspirated Focus: SOHC setups power non-turbo naturally aspirated Foresters, whereas Turbo XT models use DOHC heads.

Subaru Impreza Engine FAQ
What is AVCS and will it work with my factory wiring?
AVCS stands for Active Valve Control System, Subaru's variable valve timing tech. As long as your original 2006-2010 Forester came equipped with single overhead cam AVCS heads, this motor plugs directly into your stock harness seamlessly.
Do I need to replace the timing belt before installing?
While all our JDM engines arrive in excellent working order, we always recommend installing a fresh timing belt, water pump, and thermostat kit during the swap since the motor is already out on a stand.
What components are included with this engine purchase?
You receive the complete JDM short block and cylinder heads assembly. You will transfer over your original alternator, power steering pump, intake manifold, and sensors from your factory motor to complete the installation.
