miata supercharger guide

The Mazda Miata (or MX-5 known elsewhere) is without a doubt the two-seater sports car icon of our generation. Launching in the late eighties and progressing through four iterations, this successful cabriolet is still in production today.

The low kerb weight, front engine, rear-wheel drive (FR) configuration has meant that all generations of the fun-focused soft top make great daily drivers, circuit cars and with the right tuning, even drift cars.

When it comes to out and out track slaying the plucky Miata comes up a little short on the power front but lucky for us Mazda fans, the aftermarket has stepped in.

Turbo charging or supercharging?

If you are new to forced induction then you may be asking yourself which of these two paths are the better option?

I’ll let Marty and Moog explain the difference with an extremely scientific test..

All caught up? Great.

Forced induction

The aftermarket has a plethora of options for Miatas, both of the turbocharged and supercharged varieties.

In this guide we are focusing solely on the superchargers that are available today.

Unfortunately, as the early generations of the Miata are nearing thirty years of age, some aftermarket options have fallen off the table so with this guide we aim to offer you options that you can order right now.

Supercharged Miatas in the media

Matt Farah of The Smoking Tyre YouTube channel takes a fourth generation (ND) Mazda Miata equipped with a Flyin’ Miata supercharger system for a review down his favourite canyon run.

Still not convinced on forced induction for your Miata? Try this compilation of the best Miata sounds with over twenty different cars that are turbo charged, supercharged or tuned naturally aspirated.

Rotrex Supercharger Kit for Mazda Miata (NA)

Our comment: Supercharging options for the classic NA platform Mazda Miata are thin on the ground in 2018, after some research a well regarded kit that is still available today is this Rotrex offering.

While the entrry level price is strong, this kit offers everything you need to double the stock bhp of your 1.6 Miata.

An intercooler and supporting hardware should enable you to run this power level without compromising on your Mazda’s reliability.

Manufacturer description:Ready for over 200 RWHP out of your stock 1.6? Fast and reliable HP in a Miata. Kit includes the ROTREX Supercharger, intercooler, all required mounting hardware and detailed installation instructions.

Kraftwerks Supercharger Kit for Mazda Miata (NB)

Our comment: The highly regarded Kraftwerks kit uses a Rotrex supercharger at it’s core and a complete package of supporting components to upgrade your NB model Miata.

We like this kit as it offers a huge dose of additional performance, with little or no fabrication required. Kraftwerks do a great job of offering a true bolt on kit that includes everything from fuel injectors, engine management and intercooler.

Manufacturer description:KraftWerks is proud to introduce its completely redesigned Mazda Miata supercharger systems, available for 1998-2008 Mazda Miata.

Like all KraftWerks supercharger kits, Miata systems are based off of the impressive Rotrex supercharger and include everything necessary for a truly bolt-on installation.

At the heart of each KraftWerks Miata kit is the Rotrex C30-74 centrifugal supercharger. Rotrex’s patented traction drive technology works unlike any other supercharger, and means that power’s always available, all the way to redline. The results are impressive: 195 hp and 150 lb-ft torque on 1.8L engine.

Each Miata supercharger system is a comprehensive design and includes all necessary components to ensure safe, reliable operation. Standard-issue with each kit is a large, front-mount intercooler to help ensure low intake air temperatures for optimal performance. All necessary aluminum tubing, silicone couplers, and clamps are also included for easy installation. Proper air/fuel ratios are ensured with the included Grams Performance 350cc/min. fuel injectors, DeatschWerks 255 lph fuel pump, and electronic fuel box. Convenient, plug-and-play fuel injector adapters are also included, making each kit a true bolt-on experience.

Rotrex superchargers are renowned for their compact size, high adiabatic efficiency, low vibration, and quiet operation. Their unique traction drive technology is what makes all of this possible, which, unlike other superchargers, transmits power through frictional forces between its rolling elements. Each Rotrex unit features its own self-contained oiling system that remains independent of the engine. Its dual-action oil pump supplies traction fluid to the supercharger while the supplied cooler ensures proper fluid temperatures at all times.

Features

  • 1998-2005 kit: 195 hp / 150 lb-ft torque @ 9.5 psi (#150-10-9805B)
  • Rotrex C30-74 supercharger (optional C30-94)

Flyin’ Miata Supercharger Kit for Mazda Miata (NC)

flyin miata supercharger mazda miata nc

Our comment: The Flyin’ Miata kit for the NC model Miata offers great performance, comprehensive installation package and excellent customer feedback. The kit has even been tested on official Mazda cars which speaks volumes.

When compared in context with the Kraftwerks kit the value for money does pale a little, so less stars have been awarded. This is still a very good option if you have the cash.

Manufacturer description:This is a gorgeous piece of work that really wakes up the car. How good is it? Mazda USA put it on their Super20 show car. Mazda Germany put it on two show cars and even considered a limited production run. Yes, it’s engineered to factory levels.

The heart of the kit is a custom casting that incorporates an intake manifold, an air/water intercooler and the reliable and popular MP62 supercharger. The 6-rib serpentine belt drives the supercharger, using Mazda’s own automatic tensioner. It’s a very clean setup. The air/water intercooler means that intake temperatures are kept to a reasonable level, keeping the power safe for your engine and opening the door for future upgrades. Paint it black, and nobody would ever expect the engine bay was hiding such a secret.

The really delightful thing about this kit (beside its exceptional build quality) is its absolute transparency. There is nothing telling you that you’re driving a modified car. No odd noises, no lumps or bumps in power delivery (much, much smoother than the factory turbo cars were), just that your car will now pull much, much harder from low rpm to redline. Engine power increases to approximately 225 hp at the wheels for the federal version and 215 hp for the California. Basically, it turns your car into the Mazdaspeed that Mazda never made.

To put that power into perspective, Automobile tested the Super20 show car and clocked a 5.3 second 0-60 time.

Engine management is handled by a reprogrammed stock ECU. This means OBD-II compatibility and no emissions hassles even in California. You must purchase a tuning interface cable to load the ecu reflash. We will send you a map to upload using your laptop and the tuning cable. You then need to datalog your car using the same program and email the logs to us. We will tweak your file until it is perfect for your car – this may take a couple of iterations of logging. You can use the cable for future datalogging or to retrieve engine codes if necessary.

We’ve also taken it through the rigourous CARB testing for use in California, and passed with flying colors. The California version runs slightly lower boost.

Our comment: The second Kraftwerks supercharger kit in our guided is built for the NC model Miata. The Kraftwerks team have done a fantastic job of making sure that all of your component upgrade needs will be taken care of with this very affordable package.

From the robust and performant Rotrex supercharger unit itself, the cooling, the fueling and the engine management are all supplied in this kit.

Based on the performance and features we rate this kit a full five stars.

Manufacturer description:Kraftwerks has just announced the release of a brand new intercooled supercharger system for the 2006-2013 Mazda Miata MX-5. At the heart of the new system is the Rotrex C30-84, which is the same supercharger used in the extremely successful Kraftwerks 2006-2013 Honda Civic Si system.

At 10psi of boost pressure, the supercharger system produced an impressive +110whp on 91-octane through the OEM headers and exhaust. More impressive is the linear power curve throughout the entire power band due to the patented traction drive technology, which transmits power through friction forces between its rolling elements.

Our winner

Our winner is the Kraftwerks Supercharger Kit for Mazda Miata (NC)

As we are showing different generations of the Miata platform and each kit offers a range of power levels (based on supporting mods) we can’t compare each kit directly, however, what we can do is look at which kit offers the best value for money, regardless of platform.

The Kraftwerks kit for the NC model car stands out for offering great value for your cash. You are looking at a truly complete forced induction conversion, from cooling, to fueling to engine management.
