Cybul 1UZ/3UZ Engine Swap Kit V2 for Mazda MX-5 NA

Cybul 1UZ/3UZ Engine Swap Kit V2 for Mazda MX-5 NA Specifications

The Cybul V2 swap kit is the ideal mid-range solution for owners of Mazda MX-5 NA models looking to carry out a V8 swap without spending too much time and effort on bespoke parts. This version builds on the V1 kit by adding a chromoly tubular front subframe, providing sufficient clearance for the oil pan and enhanced chassis rigidity. This kit is compatible with the Toyota/Lexus 1UZ-FE and 3UZ-FE engines, renowned for their robustness, unique sound, relative compactness and excellent tuning potential.

Designed specifically for the MX-5 chassis, this kit ensures optimised engine positioning, a structure capable of withstanding the high torque of UZ engines, and a layout developed to allow easier fabrication of exhaust manifolds. It comes with a dedicated oil pan fitted with a suitable pickup and a repositioned dipstick for added convenience. The engine mounts are fitted with heat shields to protect them from the heat of the exhaust manifolds, whilst heavy-duty engine bushings have been selected to ensure long-term durability.

This V2 kit features a tubular front subframe with an oil pan guard, providing more space in the engine bay to facilitate exhaust fabrication and maintenance work. Furthermore, it improves chassis rigidity and opens up new possibilities for suspension geometry thanks to its control arm mounting points, which are raised by 18 mm, allowing the roll centre to be adjusted. Finally, this subframe retains the essential mounting points for the steering rack and accessories.
