Vortech V-2 Si-Trim Tuner Kit & Charge Cooler - Polished (2005-2006 Nissan 350Z Rev-Up) 4NZ218-128Si
Polished V-2 Si-Trim Supercharger Tuner Kit for 350Z Rev-Up
The Vortech V-2 Si-Trim Supercharger Tuner Kit with Charge Cooler (PN 4NZ218-128Si) is engineered for 2005-2006 Nissan 350Z Rev-Up owners who want maximum flexibility for custom fueling and calibration. Finished in polished aluminum, this tuner kit delivers Vortech's proven centrifugal supercharger performance while leaving injector selection, fuel system upgrades, and ECU tuning to the builder - ideal for higher-output street builds and track-focused applications.
This configuration centers on the V-2 Si-Trim gear-driven centrifugal supercharger paired with an integrated Charge Cooler to help manage inlet air temperatures as airflow and boost increase. Compared to turbocharger systems, the centrifugal design produces less heat, requires less drive power, and delivers smooth, linear power that's easier on the engine during sustained use.
V-2 Si-Trim Supercharger Technology
The V-2 Si-Trim utilizes Vortech's high-efficiency impeller and housing design developed in their supercharger test cell, along with SQ (Super Quiet) technology for near-silent operation and long-term reliability. For continued boost conditions - such as road racing - the V-2 series shares the engine's oiling system, allowing the use of external oil coolers or filters to further enhance thermal control.
Performance & Capability
- Power Gains: Significant horsepower increases with proper supporting mods and custom tuning
- Thermal Efficiency: Integrated Charge Cooler supports higher, more consistent output
- Scalability: Compatible with multiple Vortech compressor options to meet evolving power goals
Vortech 350Z supercharger systems are known for exceptional horsepower-per-dollar value, while maintaining drivability and efficiency when driven normally.
Tuner Kit Configuration
This Tuner Kit includes the same core supercharger hardware found in complete systems, but does not include fuel system upgrades or ECM reprogramming. This approach is intended for experienced tuners and racers who prefer to tailor fueling and calibration for power levels that can exceed 500 horsepower.

Supercharger Options & Important Notes
Vortech offers multiple supercharger configurations within the 350Z/G35 tuner kit platform to support a wide range of racing disciplines and boost targets.
V-2 Ti-Trim Important Note: Tuner kits equipped with the high-flowing V-2 Ti-Trim supercharger do not include a Charge Cooler. The standard 350Z/G35 Charge Cooler cannot support the airflow capability of the Ti-Trim compressor; applications using that head unit must source a Charge Cooler capable of supporting the required CFM.
