High-Performance Engine Builds, Automotive Upgrades & Trusted Parts That Deliver Power.

At Box Performance, we specialize in building and upgrading high-performance engines using top-quality parts from the most trusted brands in the industry. Whether you're looking for a full custom engine build, a performance engine rebuild, or automotive upgrades like superchargers, EFI systems, fuel systems, brake systems or ignition tuning, we deliver reliable horsepower for street and strip. Our comprehensive performance engine services and automotive upgrades are built for lasting power, precision, and drivability—because fast is never fast enough.

Performance Is About More Than Just the Engine

For an engine to perform at its best, it needs the right combination of high-performance support systems working in harmony. Even the most powerful engine can fall short if the rest of your setup isn’t properly dialed in.

Your transmission, rear gear ratio, fuel delivery system, ignition timing, suspension, and drivetrain all play a critical role in how your vehicle accelerates, handles, and responds. Whether you're building for street performance, drag racing, or track days, the engine is just one part of the performance equation—it’s the foundation, but not the whole story.

The Right Parts for the Right Results

It’s not just about adding performance parts—it’s about choosing the right components for your build and application. A mismatch can kill performance and drivability.

At Box Performance, we help you make the right choices for your setup:

• The correct fuel system size for your engine’s horsepower and fuel type
• A proper cooling system to keep temps under control—even with forced induction
• The right torque converter, gear ratio, and suspension setup for your driving goals
• Accurate ignition timing and reliable electrical components to support your power level

Our goal is to make sure every system on your vehicle works together—so you get the most out of your engine, safely and reliably.
