STILLEN 350Z Intercooled Supercharger
Powerful, Reliable and 50 State Legal
Proven on the streets and strips of the U.S. over the last several years, STILLEN makes the most reliable forced induction kits for the VQ powerplants. Our Stage 2 kit was the first forced induction kit to be CARB exempt, making it legal for street use in all 50 states. We are your supercharger experts and this unit proves it!
Twin Rotor Design
This is the same unit employed by OEM manufacturers such as Jaguar, Mercedes, Ford, General Motors, Toyota and Nissan. We chose it for the same reasons they did - excellent peak power coupled with superior low end and mid range. Check the comparison dyno chart - as you leave idle the STILLEN blower is making gobs of power and torque before the centrifugals and rotors spool up. On the street or track, this offers quicker and more user friendly power delivery.
The STILLEN engineering team worked intensively on this project for nearly a year before the first unit was sold. The scope and complexity of this project can be illustrated by the intake plenum development cycle. Several designs were tested until we arrived at a design that optimizes air flow, fuel distribution and power production. The production of the plenum is a multi step process. First the pieces are cast using a STILLEN developed mold. Each piece is then deburred in the STILLEN machine shop, then sent out for heat treating and powdercoating. It is then returned to STILLEN where it undergoes final machining. And this is only one of several hundred parts that comprise the STILLEN supercharger system!
The STILLEN supercharger is supplied to you or your installer fully tuned. Additional fuel, when needed, is supplied via a 7th injector that is mounted in the inlet tube. It is regulated via an electronic unit that is factory set for your vehicle. This also modifies the timing map to optimize it for the supercharged engine.
The result is a faster, more fun and dependable unit. The STILLEN supercharged VQ35 has a split personality. On the one hand it is has the acceleration of a rocket sled - it's fast enough to get you into or out of trouble. On the other, it is well mannered and can be driven normally around town or on the freeway. In normal driving, gas mileage is minimally affected.

About STILLEN Parts & Accessories
Steve Millen Sportparts, Inc. and STILLEN humbly started their race to the front of the pack in 1986. Starting with aftermarket mini-truck appearance packages, we quickly found ourselves fulfilling customer's requests to build products for other vehicles such as vans and full-sized trucks.
With that came performance parts, suspension pieces, and upgraded brake products such as big brake systems. Capitalizing on his racing career, and knowing what it took to make sports cars perform like no other, it was only natural for Steve Millen to branch out into the import car scene. Over two decades later, we offer a full array of products encompassing styling, performance, handling, and braking products for just about any car, truck, or SUV.
