Modified 1991 Acura NSX 5-Speed

Description

OFFERED WITHOUT RESERVE

Thanks to groundbreaking all-aluminum construction, high-revving mid-engine balance, and everyday usability, the Acura NSX fundamentally redefined expectations for exotic sports cars. Developed with direct input from Formula 1 legend Ayrton Senna, the NSX’s chassis tuning and steering precision were honed at circuits like Suzuka, resulting in a level of driver engagement and confidence that gave its European contemporaries a true run for their money.

Early NSXs like this 1991 model feature a 3.0-liter V6 paired with a 5-speed manual transmission and a limited-slip differential. With an 8,000-rpm redline, the NSX delivered thrilling acceleration when new.

This 1991 Acura NSX is finished in Berlina Black over a black and red interior with fixed Recaro bucket seats featuring harnesses. Open its doors, which have been modified with butterfly-style hinges, and you'll find a Momo steering wheel on a quick-release hub, an aftermarket touchscreen audio system, and white-face gauges.

Outside, front-end conversion from Japanese tuner house Marga Hills, a carbon fiber hood and rear wing, aftermarket side skirts and rear bumper, and staggered 18" and 19" Rays Volk Racing alloy wheels that sit in front of aftermarket brakes with drilled rotors. The V6 breathes through a set of Pride headers and Comptech exhaust system, while the suspension combines a Stanceparts Air Cup Kit up front with KW Variant 2 coilovers at the rear.

This NSX spent its first two decades registered in Hawaii and it was later registered in Arizona and California, where the seller acquired it in 2010.

This modified 1991 Acura NSX is now offered at no reserve with service records, a CARFAX Vehicle History Report, and a clean California title in the seller’s name.
