First available for the 1990 model year, the Z32 300zx twin-turbo was Nissan's flagship sports car. It employed a 3.0-litre V-6, double overhead cam, intercooled twin-turbo motor that generated an even 300hp and 283 pound-feet of torque in stock trim. Even though it was a rather portly car, the potent VG30DETT engine was able to propel the 300zx to 60mph in 5 seconds flat; that was enough to compete with anything in its class, including several much higher priced European exotics of the time. With the relatively low cost of entry, and abundant parts aftermarket, owners sought to unleash even greater power by bolting on a variety of performance upgrades.

Things you need

- Lightweight pulley set
- Performance Exhaust
- Race-spec intake manifold
Install a manual boost controller to increase the stock boost psi. A moderate increase of a few psi will not overload the stock fuel system, but will still provide substantial horsepower gains.
Bolt up an aftermarket exhaust to reduce power-robbing back-pressure and improve turbo spool. This will further enhance the boost controller upgrade and produce extra power across the entire RPM band.
Replace the factory Nissan intake manifold with a large capacity race spec unit. This upgrade will extend your available power curve by significantly increasing the supply of air into the engine.
Install a lightweight pulley set to remove unnecessary loads from the engine. This works by using reducing the amount of energy needed to operate the crank and accessory pulleys.
