Why ER Subaru Engines
We race what we build.
- Subaru-dedicated. EJ, FA20, FA/FB — boxer engines are the whole business, not a sideline.
- 20+ years of engine building. Short and long blocks ready to go, so your car isn't on a lift for months.
- Proven on track. Our drift team runs at Pikes Peak International Raceway, including the Slush Motorsport Festival. Track abuse is our R&D.
- Treated like our own. Every customer car gets the same care as the shop cars — that's the promise.
We're not the cheapest Subaru shop in Colorado — we're the one that posts real prices, uses named parts, and builds it right the first time.
