370z Z34 Z1 Motorsports Complete Sport Supercharger Kit

The Sport Supercharger Kit utilizes a smaller blower than our C38R-based kit, improving response and drivability in the range of 475-525hp. While this lowers the overhead power capabilities of the kit, it is more affordable and makes for a much more linear power band and a more enjoyable driving experience within this range of power.

THE DESIGN

In 2021, we began developing our Z1 Supercharger Kits to boost power for both street and track use. We chose a supercharger for its consistent, responsive power delivery, but our focus went beyond performance. The goal was a kit that beginners could install easily, with the premium quality expected from high-end hardware. To achieve this, we kept strict standards throughout design and production.

The brackets are precision-machined from 6061 billet aluminum with a black hard-anodized finish. Pulleys are made from 304 stainless steel and billet aluminum, with idler and tensioner pulleys running on dual sealed bearings rated far beyond their needs. These materials ensure long-term resistance to corrosion and engine-bay grime. Socket head bolts sit recessed for a clean look, while mandrel-bent aluminum charge pipes are finished in low-gloss black anodize. Multi-ply reinforced silicone couplers secure the piping for durability. A custom intercooler with brackets is included, offering a true bolt-on solution with no fabrication required.

The kit also includes a filtered intake for maximum airflow and to maintain the Rotrex blower warranty. Wire-reinforced silicone tubing positions the large filter ahead of the core support to pull in cooler air.

THE INSTALLATION

The blower comes pre-assembled to the bracket, clocked correctly, and with the drive belt pre-tensioned. Installation only requires removing the front bumper and fender liners. It’s jack-stand friendly with standard hand tools, and no lift is necessary. Modifications are minimal, with OEM items like the washer reservoir and horns only slightly affected. A complete installation guide is included and can be previewed before purchase. The kit also comes with custom fluid reservoirs, hoses, vehicle-specific brackets, and all required hardware.

After installation, tuning is required. Z1 offers tuning support through our Level 3 Supercharger Tune program. This can be purchased alongside the supercharger or after installation.

THE LEVELS

This kit is currently available in two configurations, supporting power levels from 475hp to over 525hp. Each kit is complete with the fuel system configured to support the advertised horsepower. All power levels can be purchased with a full Z1 Supercharger Tune, providing expert calibration based on tunes developed for Z1's own cars. 

Z1 engine tunes do not disable emissions control systems or the onboard diagnostic (OBD) system. The customer is responsible for ensuring the hardware they are using on their vehicle does not cause a failure to meet emissions standards.

This configuration supports up to 525hp on 93-octane fuel. E85 is not supported on this kit.


THE BLOWER

Rotrex superchargers were chosen for their reputation, quiet operation, and proven reliability. For the Sport Supercharger, Z1 found that the C38-92 headunit offered the greatest balance between linear power delivery and flexible power goals, supporting just north of 500whp in our in-house built 370Z with supporting modifications.W hen compared to the C38R, the lower drive inertia of the smaller blower improves tip-in response, making the car feel more natural when transitioning on and off throttle. When purchased in our complete supercharger kit, this headunit supports multiple power levels with estimated output ranging from 475-530+whp.

The C38 includes an integrated oil pump that functions as both a dry sump scavenging pump and an oil supply pump. To keep temperatures stable, the kit comes with a 13-row Z1 Pro-Cooler Oil Cooler Core and oil lines. A supercharger oil reservoir and 1L of Rotrex traction fluid are also included with purchase.

Includes:

Rotrex C38R Supercharger
OMNI 4 Bar Map Sensor
Billet Aluminum Supercharger Brackets
Complete Traction Fluid System
Z1 Bash Bar
Z1 Direct-Fit Intercooler
Billet Aluminum Expansion Tank

Spark plugs wear at a high rate when used with forced induction, so it is important to ensure they are in good working order. When installing your supercharger, Z1 recommends inspecting spark plugs for wear and replacing them if necessary. It is also recommended to reduce spark plug gap to 0.032" during installation. OEM VR38 Spark Plugs may be used and will already have an appropriate spark plug gap. 

Features:

Complete DIY Kit - Jack Stand Friendly!

It is highly recommended that a performance oil cooler kit be installed to maintain stable oil temperatures. Even naturally aspirated VQ37's suffer from unusually high oil temperatures, and this problem is only exacerbated with forced induction.
