What engine is in the 1991 NSX?
The 1991 Acura NSX was powered by a 3.0-liter V6 engine that was developed specifically for this iconic sports car. This high-revving, mid-mounted engine was a technological marvel that helped make the NSX a standout performance vehicle of its era.
The V6 Engine in the 1991 NSX
The engine in the 1991 Acura NSX was a 3.0-liter, 24-valve, DOHC V6 that produced 270 horsepower and 210 lb-ft of torque. This all-aluminum engine featured Honda's advanced VTEC (Variable Valve Timing and Lift Electronic Control) technology, which allowed the engine to deliver a broad and responsive power band.
The NSX's V6 engine was designed from the ground up to be lightweight and high-revving, with a redline of 8,000 rpm. This allowed the NSX to achieve impressive performance figures, including a 0-60 mph time of under 5 seconds and a top speed of over 160 mph.
Engineering Innovations
The engine in the 1991 NSX was a technological tour de force, featuring several innovative engineering solutions. Some key features included:
- Forged aluminum pistons and connecting rods for reduced weight and increased durability
- Titanium connecting rods for further weight savings
- VTEC variable valve timing system for improved power and efficiency across the rev range
- Dual overhead camshafts and four valves per cylinder for optimal airflow and combustion
- Programmed Fuel Injection (PGM-FI) for precise fuel delivery
These engineering innovations helped make the NSX's V6 engine one of the most advanced and capable powerplants of its time, contributing to the car's legendary performance and driving dynamics.

Does the old NSX have VTEC?
Honda intended its sports car to meet or exceed the performance of the Ferrari, while offering superior reliability and a lower price. For this reason, the 2.0 L V6 engine utilised in the HP-X was shelved and ultimately replaced with a significantly more powerful 3.0 L VTEC V6 engine.
Is the C30A engine reliable?
Its short-stroke design means it thrives on revs, yet it's also very reliable. The C30A's ignition coils can be short-lived, though, especially if the valve covers leak oil on them, which they are prone to do. Otherwise, this engine should easily be capable of 200k-250k miles.
