Bosch Alternator Kit for Nissan RB Egines Specifications

Original Nissan alternators today have two major disadvantages:

• They are getting older, alternators on RB20, RB25 and RB26 have more than 20 years old, sometimes up to 30 years old and often hundreds of thousands of kilometers. Their reliability becomes critical, Nissan does not make them anymore and the aftermarket offers only very few opportunities.
• Their amperage, usually between 40 and 60A, is insufficient nowadays for modified vehicles equipped with electric accessories such as high flow fuel pumps, high performance ignition, electric water pumps and fans, modern PDM and ECU, car audio…

With this observation, our partner MZR Garage has developed a kit to install a modern Bosch alternator on Nissan RB engines. This is a very common Bosch part number (used mainly by the VAG group: Volkswagen, Seat, Audi, Skoda, Porsche …), very reliable and ensuring 140A continuously. This “plug & play” kit has been designed to install a Bosch alternator as a direct replacement of the original alternator, and guarantees reliable and linear intensity and tension regardless of the load and engine rev.
