Acura NSX

From Acura press: The 2004 mid-engine NSX offers two distinct powerplants. The first is an all-aluminum 3.2-liter V-6 that produces 290 horsepower and 224 lb-ft of torque mated to a 6-speed manual transmission. The second is an all-aluminum, 3.0-liter V-6 that produces 252 horsepower and 210 lb-ft of torque mated to an electronically controlled 4-speed automatic transmission with Formula One-inspired Sequential SportShift.
Both engines are normally aspirated and are equipped with dual overhead cams, 4 valves-per-cylinder, a Variable Valve Timing and Lift Electronic Control (VTEC™) system, and a Variable Volume Induction system. They also feature Programmed Fuel Injection (PGM-FI) and a direct-ignition system that uses six individual coils, one mounted atop each spark plug, instead of a single coil for all six cylinders.

The chassis features all-aluminum construction for light weight. The 4-wheel, independent double-wishbone suspension features aluminum-alloy control arms and hub carriers front and rear to minimize unsprung weight for optimum handling.
The standard engine on the NSX is an all-aluminum, 90-degree, 3.2-liter (3179 cc), dual overhead cam, 4 valve-per-cylinder V-6 that produces 290 hp at 7100 rpm and 224 lb-ft of torque at 5500 rpm. It is mated to a 6-speed close-ratio manual transmission. Redline for this engine is 8000 rpm.

The only factory option for the NSX is an electronically controlled 4-speed automatic transmission that comes with an all-aluminum, 90-degree, 3.0-liter (2977 cc), dual overhead cam, 4 valve-per-cylinder V-6 with a top output of 252 hp at 6600 rpm and 210 lb-ft of torque at 5300 rpm. Redline for this engine is 7500 rpm.

An exclusive, electronically controlled Variable Valve Timing and Lift Electronic Control (VTEC™) system optimizes volumetric efficiency at both low and high engine RPM. A unique Variable Volume Induction System changes the configuration of the intake system in conjunction with varying engine speeds, working with the VTEC system to broaden the torque curve and increase peak power output.
