The Mazda MX-5 Miata is a sports car that has been hailed for its simple and modest design, both visually and mechanically. Despite this, a select number of fans enjoy taking their beloved roadsters to the extreme with one of the more popular modifications being a supercharger conversion. The engineers over at BRR recognize this, which is why the firm has put together a two-stage kit for the NC generation.

Enthusiasts of the MX-5 Miata might recall that through its ten-year lifespan, the NC model was available with two engines. The model launched with the older 1.8-liter four-cylinder MZR L8-DE in the European market but the USA was only given the larger 2.0-liter four-cylinder MZR LF-VE unit. In its standard state, this delivered 170 horsepower and 140 lb-ft of torque.

Previously, BRR worked in conjunction with Rotrex Superchargers to develop kits for the NA, NB, and ND generation models. For this kit, however, the company was approached by Corten Miller to build on the work it had completed with Rortex. This collaboration was perfect, as BRR admits that the placement of a supercharger in the NC was a challenge because of the compact engine bay. To make it work, it would have to remove the car's much-needed air-conditioning unit or reposition the battery to the trunk.

After attaining the rights to production, BRR and Corten Miller had put together a supercharger design that fit snug into the engine compartment. With this solution, the two arms didn't have to subject the process to the usual 12-18 month hardware and software development and validation, which means they were able to bring the product to market a lot sooner.

The BRR Stage One supercharger conversion is available for both displacements of the NC Mazda MX-5 Miata and promises a power output increase of 250 hp and 213 lb-ft. With this, a claimed 0-60 mph sprint time of 5.3 seconds has been stated. This unit, excluding installation, is priced at £4,095 ($5,440). Furthermore, you'll need to fit a sports manifold but this is not included in the package.

For the speed-freaks, the Stage Two supercharger conversion takes things up to 300 hp and 227 lb-ft. This comes with a claimed 0-60 mph acceleration time of 4.8 seconds. This too is available for both displacements but to accommodate the extra power, owners will have to apply the BBR 2.5-inch manifold back exhaust system and Stage One clutch, as per BRR's recommendation. The DIY kit is priced at £4,795 ($6,490).
