MX-5 Supercharger Kits

If you want to boost the power of your MX-5 significantly but don’t want to deal with any turbo lag, short of an engine swap, a supercharger kit for a Miata is your best bet. Delivering comparable power gains to many turbo kits and the immediate response of a naturally aspirated engine, for many, supercharged MX-5s really do give you the best of both worlds.

When it comes to supercharger kits, what’s included can also mean the difference between you finishing your project MX-5 or abandoning it entirely. At BOFI Racing, we only sell Mazda MX-5 supercharging kits that we actually rate. After all, supercharging an MX-5 shouldn’t (and doesn’t have to) mean you diminish the cult classic’s characterful performance — with smooth, linear power delivery and no spikes in torque.

Our complete Mazda MX-5 supercharger kits include everything you need to boost your car, saving you a great deal of time and effort.

We also sell a Rotrex kit for MX-5 for NA and NB (Mk1 and Mk2) models. The SPS Motorsport Rotrex Supercharger Kit is designed in Germany, having originally been developed for the racetrack and then adapted for the road. This SPS kit contains a Rotrex Supercharger with connectors, an intercooler, an air filter, SPS Motorsport 700CC flow matched injectors, a Plug and Play ECU, mounting hardware and more.

Frequently asked questions

Does supercharging reduce engine life?

Supercharging your MX-5 won’t, on its own, reduce the car’s reliability or durability. However, adding more moving parts to a car without upgrading other internal components is a recipe for potential issues. It can cause problems if the engine parts are not built to handle the stress that an aftermarket performance part can add to the engine’s functionality.

Make sure you buy high-quality supercharging kits, like those we sell, and upgrade any additional, necessary parts along with the kit.

Will I need to modify my engine’s internals to run one of these kits?

That depends on the kit you choose. Our Rotrex kits can deliver in excess of 300 bhp, necessitating the use of forged pistons and rods. If you don’t want to go that far just yet, make sure you stick to around 250 bhp – much more than that, and the standard rods simply won’t be up to the task!

How much does an MX-5 supercharger kit cost?

Supercharger kits for MX-5’s can range vastly in price, depending on what’s included in the kit. Just remember, you get what you pay for, so don’t be too tempted by cheap kits that are likely to cause performance issues down the road due to parts quality. If you need any advice, please don’t hesitate to ask our friendly team. We’re always happy to help our customers choose the parts that are right for them.
