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. This kit is not compatible with air conditioning. A custom solution is required for the hot side of the intercooler pipework. Please contact us first if you have Aircon so we can remove the outlet pipe so you can customise the kit to your application later.

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

Warranty is for replacement of a similar product, repair of the original product or refund of the purchase value only and excludes all labour and incurred charges including towing, fitting, inconvenience, and purchases of other manufacturer's products. The warranty is good for the period stated in the additional info tab from the date of purchase. Mileage warranties are for road use only and proof of mileage is required. Products must be installed by an independent experienced professional mechanic and the suspected defect must be present at the outset. The warranty does not cover damage caused by incorrect installation, failure to comply with the maintenance requirements of the vehicle, processing or otherwise changing the product, ordinary wear and tear, or any other external influences. Warranties are invalid if the product is used for racing, rallying, drifting, track days or any other form of motorsport or competition. Please refer to the manufacturer's own warranty documentation for more information.

Making a warranty claim

Proof of purchase receipt showing the date of purchase, proof of mileage at installation, proof of current mileage and invoice of the work undertaken by an independent experienced professional mechanic must be supplied along with the returned products for a warranty claim to be considered. If your vehicle needs to be used whilst your warranty claim is considered replacement parts from the same manufacturer should be purchased through BOFI Racing. In the event of a successful warranty claim, we will refund the card that was originally used to purchase the replacement parts, in full or in part depending on the nature of the claim. BOFI Racing reserves the right to make full or partial compensation at its sole discretion depending on the condition and mileage use of the returned suspect parts. For example, if you have used the part for several thousand miles before a defect is noticed, only partial compensation may be offered.
