One of the most popular and noticeable upgrades is installing a high-performance exhaust system. The stock exhaust on the NSX Hybrid is engineered to balance sound, emissions, and performance. However, upgrading to a performance exhaust can deliver a more aggressive and exhilarating exhaust note, enhancing the sensory feedback that is so important in a supercar experience.

Beyond improved sound, performance exhausts improve engine efficiency by reducing back pressure, allowing exhaust gases to exit more freely. This can translate to increased horsepower and torque. Manufacturers such as Akrapovič, Borla, and AWE Tuning offer exhausts made from lightweight titanium or stainless steel designed to fit the NSX Hybrid’s unique turbocharged V6 and electric hybrid system.

When selecting an exhaust, ensure it is compatible with the NSX’s hybrid components and emission systems to maintain legal compliance and avoid triggering error codes. Additionally, some systems include active valves that adjust sound levels depending on driving mode, preserving refinement during daily driving while unleashing a roar when pushed.

Sport Suspension Kit

Handling is a defining characteristic of the NSX Hybrid, and upgrading the suspension can further enhance cornering precision, reduce body roll, and improve overall road feedback. Sport suspension kits typically include upgraded springs, dampers, and sway bars calibrated for performance driving.

Brands like KW Suspensions, Bilstein, and Eibach offer sport-tuned coilovers compatible with the NSX. These kits allow for adjustable ride height and damping, enabling you to fine-tune the balance between comfort and performance. Lowering the ride height reduces the center of gravity, improving stability during high-speed maneuvers.

Upgraded suspension components enhance responsiveness, allowing drivers to push harder through corners with confidence. Moreover, they complement the SH-AWD system by improving chassis feedback and tire contact, maximizing the effectiveness of the torque vectoring electric motors.

Lightweight Wheels

Reducing unsprung weight is paramount in improving acceleration, braking, and cornering. Swapping the factory wheels for lightweight forged alloy or carbon fiber options can significantly enhance these aspects. Forged wheels are stronger and lighter than cast wheels, allowing for thinner designs without compromising strength.

Manufacturers such as HRE, BBS, and ADV.1 produce wheels specifically engineered for high-performance vehicles like the NSX. Opting for a staggered fitment (wider rear wheels) can improve traction and handling balance, especially under hard acceleration.

In addition to weight savings, new wheels can improve brake cooling by allowing better airflow around the brake components, reducing fade during spirited driving or track sessions. Be sure to select wheels with proper offsets and sizes to maintain accurate speedometer readings and avoid rubbing.

High-Performance Tires

Tires are the only contact point between your NSX and the road, making them arguably the most critical upgrade for improving performance. While the NSX comes equipped with high-quality tires, switching to ultra-high-performance or track-focused tires can drastically improve grip, braking distances, and cornering capabilities.

Options such as Michelin Pilot Sport 4S, Pirelli P Zero Trofeo R, or Bridgestone Potenza RE-71R offer exceptional dry and wet traction, optimized for sports cars. These tires feature advanced tread compounds and constructions that provide better feedback and responsiveness.

When selecting tires, consider your primary driving conditions. Track-focused tires excel on dry pavement but may wear faster and perform poorly in cold or wet conditions. Conversely, high-performance street tires offer a balanced approach suitable for daily driving and occasional spirited runs.

ECU Tuning and Hybrid System Optimization

The Acura NSX Hybrid’s powertrain is governed by sophisticated engine control units (ECUs) that coordinate the internal combustion engine and electric motors. Custom ECU tuning can unlock additional performance by optimizing fuel mapping, turbo boost levels, and electric motor assist strategies.

Professional tuners specializing in hybrid and performance vehicles can recalibrate the NSX’s software to improve throttle response, increase horsepower, and enhance torque delivery without compromising the hybrid system’s longevity. This requires advanced diagnostic tools and deep knowledge of the NSX’s hybrid architecture to avoid detrimental effects.

Some tuning options include:

  • Adjusting turbocharger boost pressure for increased combustion power
  • Refining electric motor torque vectoring parameters for sharper handling
  • Optimizing regenerative braking for smoother deceleration and improved energy recovery

It’s essential to work with reputable tuning specialists and ensure that any software modifications comply with local emissions regulations.

Additional Upgrades to Consider for a Complete Performance Package

Brake System Upgrades

Upgrading the braking system enhances stopping power, reduces fade during high-performance driving, and improves pedal feel. Performance brake pads, stainless steel braided brake lines, and larger rotors can be fitted to the NSX Hybrid to boost braking efficiency.

Brands such as Brembo offer upgrade kits with multi-piston calipers and carbon-ceramic rotors, providing superior heat dissipation and reduced unsprung weight. Carbon-ceramic brakes are particularly beneficial for track enthusiasts, delivering consistent performance during extended hard use.

Aerodynamic Enhancements

The NSX’s aerodynamic design contributes to its stability at high speeds. Aftermarket aero parts such as front splitters, rear diffusers, side skirts, and adjustable rear wings can increase downforce and improve airflow management. These modifications enhance grip and reduce lift, especially during aggressive cornering and high-speed runs.

Carbon fiber components not only add aerodynamic benefits but also reduce vehicle weight. When selecting aero parts, it’s important to choose products tested for performance gains and maintain the NSX’s refined appearance.

Interior and Driver Interface Upgrades

While performance is key, enhancing driver engagement through interior upgrades can elevate the overall driving experience. Performance seats with improved bolstering, upgraded steering wheels with better grip materials, and advanced telemetry systems provide better feedback and control.

Additionally, aftermarket paddle shifters or short-throw shifters can improve gear changes, complementing the NSX’s dual-clutch transmission for quicker, more precise shifts.

Maintenance and Considerations When Upgrading Your NSX Hybrid

Before undertaking any upgrades, consider that the Acura NSX Hybrid’s advanced hybrid system requires careful handling. Modifications should be installed by professionals experienced with hybrid supercars to ensure compatibility and maintain vehicle warranty where applicable.
