Our Tuner Kit is a complete system designed for DIY'ers looking for a bolt-on supercharger while still sourcing their own fuel system and tuning.  In the product options, you can select from multiple pulley sizes, providing power gains up to 225hp over stock with other supporting modifications. For those looking for a complete system that includes fuel and tuning, our complete supercharger kit can be purchased at the link below.

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

THE INSTALLATION

When we say boost for the masses, we mean it. From the start, ease of installation has been a top priority, and Z1 has already taken the first steps for you.

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.

For customers with a Z1 Catch Can Kit, a new bracket and hose kit is needed to relocate the can. These parts are available in the product options.

THE BLOWER

Rotrex superchargers were chosen for their reputation, quiet operation, and proven reliability. For the Sport Supercharger, Z1 found that the C38-81 headunit offered the greatest balance between linear power delivery and flexible power goals, supporting just north of 500whp in our drift 350Z with supporting modifications. When compared to the C38R, the smaller C38-81 improves underhood clearance, translating to less trimming and better bumper clearance. 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 375-475+whp.

"The C38-81 is awesome. It feels progressive and linear, which makes it much easier to drive in partial throttle/load situations. The car even runs a bit cooler compared to the C38R, which is essential when we're driving it hard."

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.
