The California-based tuning firm Stillen has launched a supercharger kit for the 2010 Nissan 370Z and Infiniti G37. With this package, Nissan 3.7-liter V-6s is able to generate 515 hp. Stillen's engineers made sure that the engine could handle the power.
The internals are actually already strong enough to take the extra boost, but there was a need for the cooling system to be boosted to maintain a normal operating temperature for the engine.
Stillen achieved its goal with the use of an air-to-water intercooler integrated into the new high-flow cast aluminum intake manifold, along with additional oil and transmission coolers.
The supercharger kit also includes larger 600-cc fuel injectors, a high-output fuel pump, Y-pipe cold air intake, and a revised engine computer. With these modifications, the car can produce 515hp and 343 pound-feet of torque. This is certainly a substantial upgrade, considering the six-cylinder usually delivers only 332hp and 270 pound-feet of torque.
The Stillen supercharger package is offered with a full engine warranty. It's made more appealing with Stillen's assurances that it has been tested in all conditions (from track driving to rush hour traffic).
Typically, supercharger kits require dealer installation but this kit is an easy-install one. Many components are pre-assembled and the kit comes with detailed step-by-step instructions.
