Summer 2025 Release


At last an affordable supercharger conversion for MX-5 MK1, MK2 & MK2.5 models.


To complete our MX-5 Rotrex supercharged portfolio covering all MX-5 models we will be releasing our final conversion as hardware only and as a complete package with injectors and ECU, for both installed and DIY fitments.

Using the proven and reliable Rotrex supercharger unit, BBR’s supercharger package has been designed to install without intrusive mechanical alterations onto the 1839cc Mazda BP-series engines. As with all BBR conversions, the under bonnet appearance remains OEM-like and discrete.


BBR Supercharger Package Parts will include:

  • C30-60 Rotrex Supercharger
  • Rotrex Oil reservoir
  • Optional BBR Oil Cooler
  • BBR High Quality Anodised CNC Rotrex brackets
  • BBR High Quailty Anodised CNC Tensioner brackets
  • BBR spec revised ancillary belt and tensioner
  • BBR high flow K&N Typhoon induction kit
  • BBR Front mounted intercooler
  • BBR branded Intercooler silicone hoses
  • BBR Temperature sensor
  • BBR Recirculating piston type dump valve in factory black finish
  • Optional High flow Bosch fuel injectors
  • Optional Motorsport Electronics ECU
  • Hardware only and Complete package choices for DIY clients

Power increases of 80-100BHP on stock vehicles, 245BHP+ is achievable on a completely otherwise standard late MK2.5.

We estimate the finished MX-5 NB DIY kit price to be under £3500 (ex VAT) excluding ECU at time of release, the NA (MK1) model slightly more.
