This comprehensive guide synthesizes expert insights, detailed technical approaches, and practical considerations aimed at enthusiasts, collectors, and professional restorers alike, seeking to return these models to their former splendor or push beyond original limits.
The Historical Context and Significance of the 1999 Acura Integra

The late 1990s marked the culmination of Acura’s first-generation Integra lineup, with the 1999 model standing out as a particularly noteworthy edition. Launched in 1994, the Integra was celebrated for its precise chassis, peppy high-revving engines, and refined yet sporty aesthetics. By 1999, Acura refined the design with subtle updates—most notably the introduction of the Type R variant, which has since become a collector’s icon. Engineering advances such as improved suspension geometry, lightweight body components, and a focus on driver-centric features contributed to its reputation as a quintessential driver’s car.
The model's historical importance is cemented not only by its performance but by its cultural impact—especially among the tuner community—where it became a staple for modifications and racing projects. Restoring a 1999 Integra therefore involves not merely technical refurbishment but also reverence for its place in automotive history. Understanding this context guides restoration priorities, whether preserving originality or integrating modern enhancements.
Core Principles of Restoring a 1999 Integra

Effective restoration of this classic hinges on a balance between authenticity, safety, and performance. Central to this process is establishing a thorough assessment of the vehicle’s current condition, including body integrity, mechanical components, electrical systems, and interior preservation. Experts recommend adopting a systematic approach: beginning with detailed inspections, followed by strategic planning, sourcing authentic or quality aftermarket parts, and executing repairs with precision.
Key principles include adherence to original specifications for parts and finishes where authenticity is paramount, alongside embracing contemporary advancements to improve reliability and safety—such as upgraded brake systems or modern electronic modules—without detracting from the vehicle’s authentic character. Achieving this harmony elevates the Integra’s personality while ensuring it functions optimally for daily driving or show purposes.
Detailed Methodology for Restoring the Exterior and Bodywork
The exterior of the 1999 Integra encapsulates its instinctively sporty silhouette, characterized by a low, aggressive stance, clean lines, and distinctive pop-up headlights. Restoring this aspect begins with meticulous surface evaluation—identifying rust issues, dents, or corrosion. The body panels, often prone to rust especially along wheel arches, sills, and the lower doors, require expert diagnosis.
For areas with minor flaws, professional sanding, spot filling, and refinishing can recover original contours and finishes. When facing extensive rust or damage, panel replacement with OEM or high-quality reproductions preserves authenticity. Paintwork must adhere to factory color codes—such as the iconic Granada Black Pearl or Championship White—to safeguard original aesthetics. Additionally, attention to detail in restoring emblems, badges, and trim enhances the overall appearance.
This process benefits greatly from techniques like soda blasting or chemical stripping for old paint removal, combined with high-quality primer and clear coats. The goal is to replicate the factory finish while ensuring durability compatible with future use.
Critical Aspects of Restoring the Chassis and Underbody
Restoration of the chassis requires addressing rust holes, frame integrity, and suspension mounting points. An expert’s diagnostic approach includes ultrasonic testing or x-ray inspection for hidden corrosion and structural weaknesses. The underbody’s preservation is vital for safety and handling—areas such as the subframes, exhaust mounting points, and wheel wells must be treated accordingly.
In cases where rust consolidation or replacement is necessary, using galvanized steel or reinforced panels guarantees longevity. Suspension components—control arms, bushings, shocks—should be inspected for wear; replacing these with OEM or performance parts enhances handling and ride quality. Finally, applying underbody coatings, similar to the original factory seal, offers corrosion resistance while preserving the vehicle's authentic feel.
| Relevant Category | Substantive Data |
|---|---|
| Rust Repair | 300+ hours of dedicated prep and treatment for heavily corroded areas on average |
| Paint Matching | Exact factory colors can be reproduced with a 98% color match precision using OEM formulas |
| Structural Reinforcement | Frame stiffening kits increase chassis rigidity by approximately 15% for aggressive driving |

Drivetrain and Mechanical Components Restoration
The heart of a restored Integra is its drivetrain—specifically, the B-series engines that powered the Type R and GS models. These engines are renowned for their high-revving nature, with the B16 series producing approximately 160 horsepower, and the B18 series reaching up to 197 horsepower in the Type R variant.
Restoration begins with a comprehensive overhaul of the engine bay components—replacing worn pistons, valve guides, timing belts, and gaskets with OEM parts to ensure authentic performance. For road usability and reliability, upgraded intake manifolds, headers, and exhaust systems are popular choices, with many enthusiasts opting for bolt-on aftermarket parts that complement the original setup.
Transmission rebuilds, especially of the close-ratio manual gearboxes, can drastically improve shift feel, a hallmark of the Integra’s driving appeal. Upgraded clutch assemblies and lightweight flywheels further enhance responsiveness. Additionally, refreshing the cooling system, including radiators and thermostats, prevents overheating during spirited driving.
Modern braking systems can be retrofitted to improve safety: larger rotors, multi-piston calipers, and braided steel brake lines significantly reduce brake fade and improve modulation during high-performance use. Brake fluid replacement must adhere to high-temperature fluids like DOT 4 or better standards.
Electrical and Interior Systems Revival
Electrical systems on the 1999 Integra are straightforward but require careful troubleshooting—faulty wiring or aging connectors often induce issues with lighting, sensors, or instrument clusters. Restorers should prioritize replacing aging wires and restoring gauges to their factory calibration for an authentic appearance.
The interior, long susceptible to sun damage and wear, benefits from deep cleaning, upholstery repairs, and if necessary, OEM replacement seat covers and trim parts. Restoring original dashboard plastics and panels, or upgrading with subtle modern enhancements like improved audio systems, can modernize usability while maintaining vintage charm.
| Relevant Category | Substantive Data |
|---|---|
| Engine Rebuild | Over 2000 hours of detailed work typically needed for a full restoration, ensuring OEM specifications |
| Brake Upgrades | Increase stopping power by up to 35% compared to stock configurations with performance kits |
| Electrical | Rewiring kits available that reduce electrical faults by as much as 40% |
The Art of Authenticity Versus Performance Enhancement

Restoration philosophies tend to be dichotomous: some purists emphasize unwavering originality, while others embrace performance upgrades to enhance driving experience. It’s essential to develop a clear vision aligned with personal goals—whether restoring to factory correctness or creating a bespoke modified vehicle.
If authenticity reigns, sourcing from reputable OEM parts, verifying paint codes, and preserving original trim components should be prioritized. Conversely, if performance enhancements are desirable—such as coilover suspension, limited-slip differentials, or turbocharging—these should be integrated with meticulous attention to compatibility and balance.
Both approaches demand an understanding of the Integra’s foundational engineering. For example, aftermarket turbo kits must be calibrated to maintain engine reliability, while suspension modifications should respect chassis geometry to prevent tire wear and handling issues.
Key Points
- Authenticity matters—original parts and finishes preserve value and historical integrity.
- Balanced upgrades—performance enhancements should complement and not compromise drivetrain reliability.
- Professional execution— partnering with experienced restoration specialists ensures accuracy and quality.
- Documentation—maintaining meticulous records of parts, modifications, and procedures boosts future value.
- Long-term planning—restoration is an investment that benefits from strategic, phased execution.
