Why Choose Us for Performance Engine Building in San Diego

For decades, our Performance Engine Building San Diego team has engineered custom solutions for classic builds, late-model upgrades, and full race applications.

Custom engines specifically designed, built, and tuned for your specific vehicle and application. While AntiCrate™ engines are made individually to your needs, crate engines are mass-produced and built to be uniform. Get an engine built for your needs.

We take decades of application experience combined with today's best components to create the best engine product for meeting your unique needs. Applying modern cost-effective parts allows for the perfect adjustment of vacuum, windage control, fuel requirements, camshaft power, timing curves, and more to go along with your desired power and torque. Don't just get the best on paper, build the best for your car.
