JBA is San Diego’s Home for Performance
We’ve spent over 40 years tuning, building, and perfecting cars for people who expect more than stock. Whether you drive a late-model Mustang or a vintage GTO, we don’t just fix—we upgrade!
Built on Muscle. Tuned for Today.
We’re not a dealership. We’re not an e-comm warehouse. JBA is a full-service performance center rooted in American car culture—with modern capabilities to match. Here’s what sets us apart:
- In-house mechanics, fabricators, and tuning specialists
- Proven track record in engine builds, swaps, and emissions-compliant performance
- Full tire shop, dyno, and service center
- Direct install support for every part we sell
- Monthly Coffee & Cars on the Mesa meetups and community events
Whether you’re chasing 9s or just want to wake up your daily driver, we’ve got you covered.
Speed shop—Everything in One Place
You shouldn’t have to jump from one shop to another. JBA handles the full stack of performance upgrades, diagnostics, and fabrication—all under one roof.
Built Right. Built Here.
Want to know what we’re capable of? Just look at the cars we’ve built. From 1,000+ HP street monsters to California-legal muscle cars, our team doesn’t just install—we engineer. And when off-the-shelf parts don’t cut it, we build our own.
- Signature performance kits engineered in-house
- Stage 1–3 upgrade paths
- Turnkey project builds
- Proven track and street results
