the march engine has a turbo and supercharger
In 1988, Nissan launched a limited 10,000 unit run of its homologated Nissan 1989 March Superturbo (EK10GFR/GAR). Both this and the 1988 March R (EK10FR) featured the same highly advanced sequential compound charged (supercharger plus turbocharger) engine in an all-aluminium straight-4 930 cc 8-valve 4 cylinder Nissan MA MA09ERT unit that produced 110 PS JIS (81 kW/108 hp) at 6400 rpm.
