Subaru

All of our Subaru engines are remanufactured at Sunwest Automotive Engine with state-of-the-art equipment under the strictest standards using only premium quality parts. Our full remanufactured engines are built to meet or exceed exact OEM specifications. We sell long blocks, short blocks, and cylinder heads. We offer a variety of options including performance packages with forged internals for people that like to go fast.

All engines are remanufactured at Sunwest Automotive Engine in Medical Lake, WA. We ship nationwide for very reasonable prices. Engines are sold on an exchange basis. There is a core deposit required that is refundable, as long as your core that we receive back is rebuildable.
