Nissan MA 09ERT Engine
The Nissan MA09ERT is an enhanced version of the MA10ET. This was introduced to the Nissan Micra SuperTurbo around 1988. The engine was slightly reduced in displacement, but expanded with a Roots compressor on the four-cylinder water-cooled OHC engine . This increased the performance of the 75hp MA10ET to 110hp with a larger throttle body uprated intercooler and intake manifold
