MX5 1800 Engine


Mazda MX5 1800

We guarantee you the best price on any Rotrex supercharger kit, even when including installation and custom tuning.

How can we guarantee this? Because we are the official Rotrex distributor for all of Australia and New Zealand, and have been so more than a decade. Due to our massive buying power with Rotrex we can obtain any supercharger kit cheaper than the competition, and can then pass this discount on to you, our customer.


Bullet Cars is pleased to release the first Rotrex supercharger kit to suit the Mazda MX5 1800 engine. Developed and manufactured in house, the Mazda MX5 installation is an exciting OEM style kit that will transform your standard MX5 into the exciting sports car it should have been!


Designed to suit an internally standard engine, the Intercooled Bullet MX5 kit reliably increases power from the factory 98kw at the wheels  up to 135kw or 150 kw! This is a gain of over 50% and is achieved with only 8 or 9psi of boost pressure. Additional power increases to over 170kws can be made with the fitment of Cold air induction, High flow Extractors and exhaust and a slight increase in boost pressure to 11psi. The power delivery from the Rotrex Supercharger is extremely smooth and feels like a factory installation. With unmatched boost response and silent operation, the Rotrex is THE centrifugal supercharger to have. It really does turn the MX5 into an exciting well balanced sports car!
