What type of drivetrain does the 1990-2005 Acura NSX use?
The 1990-2005 Acura NSX features a rear-wheel-drive (RWD) layout with a mid-engine configuration. It utilizes a 5-speed manual transmission or an optional 4-speed automatic transmission (available from 1994 onwards). The drivetrain is designed to optimize weight distribution and handling performance.
Q2 What is the gear ratio of the 5-speed manual transmission in the NSX?
What is the gear ratio of the 5-speed manual transmission in the NSX?
The 5-speed manual transmission in the 1990-2005 Acura NSX has the following gear ratios: 1st gear - 3.071:1, 2nd gear - 1.952:1, 3rd gear - 1.400:1, 4th gear - 1.034:1, 5th gear - 0.771:1. The final drive ratio is 4.062:1 for models with manual transmission.
Q3 What is the torque capacity of the NSX drivetrain?
What is the torque capacity of the NSX drivetrain?
The drivetrain of the 1990-2005 Acura NSX is engineered to handle up to 210 lb-ft of torque, which is the maximum torque output of the 3.0L or 3.2L V6 engine. The drivetrain components, including the transmission and differential, are designed to withstand this torque under normal operating conditions.
Q4 How often should the differential fluid be replaced in the NSX?
How often should the differential fluid be replaced in the NSX?
Acura recommends replacing the differential fluid in the NSX every 30,000 miles or 24 months, whichever comes first. Use only genuine Acura Dual Pump Fluid II (P/N 08200-9006) to ensure proper lubrication and performance of the limited-slip differential.
Q5 What type of differential does the NSX use?
What type of differential does the NSX use?
The 1990-2005 Acura NSX is equipped with a torque-sensing limited-slip differential (LSD). This differential enhances traction and stability by distributing torque between the rear wheels based on driving conditions, improving cornering performance and reducing wheel spin.
