About DOS

Dos Performance was built from hands-on experience, not a business plan.

What started as working on our own Subarus quickly turned into something more. As we pushed our own cars further, we dove deeper into engine building, tuning, suspension setup, and racing. Over time, that passion turned into more than just personal projects. It became expertise.

With over 15 years of experience in Subaru performance, we began developing aftermarket turbo solutions to solve the limitations we experienced firsthand. We wanted more power without sacrificing spool, reliability, or drivability; especially in stock-location turbo setups. That commitment to real-world performance is what shaped our early turbo development and established Dos Performance in the aftermarket space.

Located high in the Eastern Sierra mountains, we have the unique advantage of developing and testing components in demanding conditions that many manufacturers never face. High elevation, changing weather, and harsh terrain expose weaknesses quickly and that forces better engineering. If it performs here, it will perform anywhere.

As demand grew, so did we.

Today, Dos Performance is a full-service Subaru performance and repair shop offering dealer-level diagnostics alongside high-performance builds. We service everything from daily drivers to dedicated track cars, providing:

• Factory maintenance and oil services

• Advanced Subaru diagnostics

• Engine repair and complete rebuilds

• Custom turbo systems and upgrades

• Built short blocks and race motors

• Suspension setup and brake upgrades

• Track preparation and trackside support

We didn’t start by trying to open a shop. We started by trying to build our own Subarus better. The shop came naturally as others trusted us to do the same for them.

At Dos Performance, Subaru isn’t just a market segment. It’s what we know, what we build, and what we continue to push forward.

Build it right.
Make it reliable.
Make it perform.
