Power Adders & Engine Builds in Hemet
JEP Autoworks has built its reputation on performance. From the shop's founding in 1999, performance work has been at the core of what we do: engine builds, forced induction installs, and custom fabrication for street cars, track cars, and competition vehicles where applicable. We work on domestic and import platforms and have experience across a wide range of builds from mild street upgrades to high-horsepower race vehicle preparation.
Performance upgrades work best as planned systems. We help match parts, fuel system, exhaust, cooling, and drivetrain to the goal of the vehicle rather than stacking parts that work against each other. Emissions-compliant and CARB-legal options are used where required for the application.
Chassis dyno tuning, data logging, and dyno rental are available in-house. See Dyno Tuning & Rental.
