Spec 90-98 Nissan SR20DET S13/S14 Mini Twin D-Trim to EVO Gearbox Clutch Kit

The dual-disc design of this SPEC Mini Twin clutch kit features two 8-inch friction discs, a significant detail that allows for a substantial increase in holding capacity compared to a single-disc setup. This is crucial when adapting a Nissan SR20DET engine, commonly found in S13 and S14 chassis, to an EVO gearbox, a combination often pursued for its robust performance potential. The kit is engineered to handle the higher torque and power output that these builds typically aim for, ensuring reliable engagement and power transfer.

SPEC utilizes a D-Trim input shaft design for this kit, specifically matching the spline count and diameter required for the EVO transmission. This ensures a proper, direct fit without the need for modifications to the gearbox itself. The twin-disc configuration not only boosts holding power but also helps to dissipate heat more effectively, which is vital for maintaining clutch performance during aggressive driving or repeated launches. The kit includes all necessary components for installation, making it a comprehensive solution for enthusiasts looking to complete this specific engine-to-gearbox swap.

When undertaking a swap like this, it's important to ensure all supporting components are in good condition. This clutch kit is designed to be a high-performance solution, and its effectiveness will be maximized when paired with a properly functioning flywheel and a compatible hydraulic system. Refer to the manufacturer's installation instructions for detailed guidance on proper setup and break-in procedures to get the most out of this well-built clutch system.
