This Subaru Outback with the EJ253 (non turbo 2.5) came in for smoking out the exhaust. It is common for these older engines to drop exhaust guides.

We upgrade the guides to GSC Power-Division manganese bronze with stoppers to prevent this from happening again!

Full valve job, resurface, Cleaning, new GSC valve stem seals, updated OEM MLS head gaskets, and a complete reseal. Good for another 200k miles!

We're proud that the car ran flawlessly the entire event on our FA24 setup, paired with Karcepts and MCS suspension.

Not every project that comes through our shop is a high-horsepower build.

Paul's latest Tech Talk features a Subaru Outback getting a remanufactured engine.

The owner loves the car and decided it's worth investing in keeping it on the road.

From daily drivers to performance builds, we help Subaru owners get the most out of their vehicles.

Would you replace the engine in a car you love, or buy something new?👇
