The Acura Integra GSR is a legendary car among enthusiasts, known for its performance, handling, and timeless design. When you start talking about a custom 2001 Acura Integra GSR, you're entering a realm where individuality meets automotive passion. This article dives deep into what makes a custom Integra GSR special, covering everything from performance modifications to aesthetic enhancements.

Understanding the Acura Integra GSR Legacy

Before we get into the custom aspects, let's appreciate the Integra GSR for what it originally was. Produced from 1992 to 2001, the GSR trim (Grand Sport Racing) was a step above the base Integra, offering a more powerful engine and sport-tuned suspension. The heart of the GSR was its B18C engine, a high-revving, naturally aspirated four-cylinder that made around 170 horsepower. This engine, combined with a slick-shifting five-speed manual transmission, made the Integra GSR a blast to drive.

Why the Integra GSR is a Great Platform for Customization:

• Engine Potential: The B18C engine is known for its robust design and ability to handle significant power increases with the right modifications. From simple bolt-ons to full engine builds with aftermarket internals, the possibilities are vast.
• Handling Prowess: The Integra's double-wishbone suspension provides excellent handling characteristics. Upgrading the suspension components can further enhance its cornering abilities, making it a formidable track car or canyon carver.
• Timeless Design: The Integra's sleek lines and sporty stance have aged gracefully. Its simple yet attractive design makes it a great canvas for aesthetic modifications, whether you're going for a subtle OEM-plus look or a wild, attention-grabbing style.
• Community Support: The Integra has a large and active community of enthusiasts who are always willing to share their knowledge and experience. This makes it easier to find information, parts, and inspiration for your custom build.
• Affordability: Compared to many modern sports cars, the Integra GSR is relatively affordable, making it an accessible platform for enthusiasts on a budget.

Common Customizations for the 2001 Acura Integra GSR

Performance Modifications

When it comes to boosting performance, the B18C engine is a goldmine. Here are some popular modifications:

• Intake and Exhaust: Upgrading the intake and exhaust systems is one of the first steps many enthusiasts take. A cold air intake can improve airflow to the engine, while an aftermarket exhaust system can reduce backpressure and increase horsepower. Brands like AEM, Injen, and Skunk2 are popular choices.
• Engine Management: To get the most out of your modifications, you'll need to tune the engine's computer. Hondata and Neptune are two popular engine management systems that allow you to adjust various parameters, such as fuel and ignition timing.
• Forced Induction: For serious power gains, many Integra owners opt for a turbocharger or supercharger. A properly installed and tuned turbo kit can easily double the horsepower of the B18C engine. Companies like Garrett, Precision Turbo, and Edelbrock offer turbocharger and supercharger kits for the Integra GSR.
• Internal Upgrades: For those looking to build a high-horsepower engine, upgrading the internal components is essential. Forged pistons, connecting rods, and crankshafts can handle the increased stress of forced induction. Brands like Wiseco, Eagle, and Brian Crower are popular choices.
• Nitrous Oxide: A nitrous oxide system can provide a quick and affordable boost in power. However, it's important to use nitrous responsibly and ensure that your engine is properly tuned to avoid damage.

Handling and Suspension Upgrades

To improve the Integra's handling, consider these modifications:

• Coilovers: Coilovers allow you to adjust the ride height and damping of your suspension. This can improve handling and give your Integra a more aggressive stance. Brands like Tein, KW, and Bilstein offer high-quality coilovers for the Integra GSR.
• Sway Bars: Upgrading the sway bars can reduce body roll and improve cornering stability. Aftermarket sway bars are typically stiffer than the factory units, providing a noticeable improvement in handling.
• Bushings: Replacing the worn-out rubber bushings with polyurethane or spherical bearings can improve suspension response and reduce unwanted movement. Energy Suspension and Hardrace are popular brands for bushings.
• Strut Tower Bars: Strut tower bars connect the strut towers, reducing chassis flex and improving handling. These bars are relatively inexpensive and easy to install.
• Brakes: Upgrading the brakes is essential for improving stopping power. Larger rotors, calipers, and performance brake pads can significantly improve braking performance. Brands like Brembo, StopTech, and Wilwood offer brake upgrades for the Integra GSR.

Aesthetic Enhancements

• Body Kits: A body kit can give your Integra a more aggressive and personalized look. Popular body kit styles include the Mugen, Wings West, and VeilSide kits. However, it's important to choose a body kit that complements the Integra's design and doesn't look out of place.
• Wheels and Tires: Upgrading the wheels and tires can dramatically change the look and performance of your Integra. Lightweight wheels can improve acceleration and handling, while performance tires can provide better grip. Popular wheel brands include Volk Racing, Work, and Enkei.
• Paint and Body Work: A fresh coat of paint can make your Integra look like new. Consider choosing a unique color or adding custom graphics to make your car stand out. Quality bodywork is essential for ensuring that the paint looks flawless.
• Interior Modifications: Upgrading the interior can make your Integra more comfortable and stylish. Popular modifications include aftermarket seats, steering wheels, and shift knobs. Recaro, Sparco, and Momo are popular brands for interior accessories.
• Lighting: Upgrading the headlights, taillights, and interior lighting can improve visibility and give your Integra a more modern look. LED headlights and taillights are a popular choice.
