Custom Builds & Modernization

Many collectors want the soul of a classic with the confidence of modern performance. Unique Customs specializes in thoughtful upgrades that enhance drivability, safety, and comfort — without sacrificing character.

Our customization work is engineered, not improvised.

Each modification is selected to complement the vehicle — never overpower it.

Engine Builds and Crate Engine integration

Power is built with purpose. We design and install custom engine builds or integrate high-quality crate engines to deliver reliable performance tailored to your driving goals. Every installation is engineered for proper fitment, cooling, and long-term durability.

Transmission and drivetrain upgrades

Modern performance demands modern control. We upgrade transmissions and drivetrain components to improve drivability, efficiency, and strength—whether through overdrive conversions, reinforced components, or complete drivetrain modernization.

Electronic Fuel Injection (EFI) Conversions

EFI brings classic engines into the modern era. We convert carbureted systems to electronic fuel injection for improved cold starts, throttle response, and reliability—while maintaining a clean, period-appropriate appearance under the hood.

Disc brake and suspension upgrades

Confidence comes from control. We modernize braking and suspension systems to deliver improved stopping power, handling, and ride quality. Each upgrade is selected and tuned to complement the vehicle’s weight, power, and intended use.

Custom exhaust fabrication

Sound and flow matter. We design and fabricate custom exhaust systems that optimize performance while delivering the right tone and character. Every system is built in-house for proper clearance, balance, and visual refinement.

Dyno tuning and performance optimization

Precision tuning unlocks full potential. Using dyno testing, we fine-tune engines and drivetrains to maximize power, efficiency, and reliability—ensuring every component works together as a cohesive system.

Vintage-integrated air conditioning systems

Comfort without compromise. We integrate modern climate control systems discreetly into classic interiors, delivering reliable cooling while preserving original aesthetics and cabin design.

Modern audio, navigation, and electrical upgrades

Modern convenience, seamlessly integrated. We upgrade audio, navigation, and electrical systems using discreet components that enhance usability without disrupting the vehicle’s classic character or interior styling.
