SR1 Supercharger Kit For Mazda MX-5 NA NB

The SR1 Supercharger Kit For Mazda MX-5 NA NB fits both 1.6 and 1.8 MX-5s from 1989 to 2005. We’ve taken the Salon Motorsport kit and added a bundle of parts that ensure complete reliability and maximum power.

The Eaton supercharger taken from the Mini Cooper S provides a significant jump in power. The roots style positive displacement supercharger instantly generates the same amount of boost across the whole RPM range, retaining the original throttle response but with the grunt of a bigger engine. Power is available instantly, making the MX-5 an even more formidable B-road machine, with exceptional track manners to boot.

The SR1 kit contains everything you need for bolt-on power.

Please note, some of these products are shipped separately and may arrive at different times.

    When is it deemed that it will be back in stock

  2. Tom

    Does this kit include all the pipings ?

    If not, do you provide a list of everything needed ?

    • Leigh Gray

      Hi Tom. This kit includes all the intercooler pipework you need to fit the supercharger kit.

  3. Mike

    Hello, the AEM wideband sensor replaces the stock one in the manifold?

  4. Antony Lowde

    Apologise not a review just a question what power gains are predicted from the standard install?

We Can Install This For You

We've designed our workshop services to be easy to book and pay for online. To book, you'll need to pick a date and time that suits you and then add the products you want to be installed.

Each workshop product is a labour price only. We've recommended some products on each page, but you can also find other compatible products at the bottom of the page. This way, you know exactly what product you're getting and how much its costing to fit.

Add both the workshop service as well as the product to be installed to your basket and proceed to the checkout. Once there, you can confirm your dates and process the order. Occasionally, some products may require confirmation, when this happens we will make sure we have the stock to fulfil the install and get back to you within 1 working day.

If you have any questions, want a bespoke installation or would prefer to book over the phone, give us a call on +44 (0) 203 795 0515 or send us an email at [email protected]
