Nissan MA engine#MA10ET

The MA09ERT is a twin-charged design (possessing both a turbocharger and a supercharger), an unusual design, particularly for Japanese vehicles.{{cite web |title=日産・マーチR/スーパーターボに搭載のMA09ERT型エンジンについて |url=https://minkara.carview.co.jp/userid/139692/car/61409/75311/note.aspx |website=Minikara Carview |access-date=17 January 2017 |trans-title=About the MA09ERT engine installed in the Nissan March R/Super Turbo |date=17 December 2006 |language=ja}} It powered the March Superturbo, March R, and the March Superturbo R.

The "Nissan PLASMA" (Powerful & Economic, Light, Accurate, Silent, Mighty, Advanced) improved performance and response by adding a supercharger to the (already turbocharged) MA10ET engine, which is a four-cylinder water-cooled OHC engine with a V-type valve arrangement and hemispherical combustion chambers, with sequential fuel injection.

The supercharger improved the response and the output in the low-rpm region (where turbochargers are typically less effective), and a new larger HT10 turbocharger aimed to improve output in the high-rpm regions. An intercooler and an updated intake manifold were added, the latter having a much larger throttle body and improved fuel rail. The result was an increase in output to {{cvt|110|PS|kW hp|0}} from {{cvt|85|PS|kW hp|0}}, and a much broader range of torque. Other changes included a reduction of engine capacity from 988 cc to 930 cc; this strengthened the engine by increasing the bore wall thicknesses by 1 mm, and allowed cars using it to enter sub-1300 cc competition classes not otherwise possible due to conversion factors applied to forced induction engines.

The first prototypes of these engines were installed in the March Superturbo R/March R (EK10FR type) in 1988; shortly thereafter the engine was installed in the March Superturbo.

The MA09ERT was the first twincharged engine available in Japan; series charging combines the increased low-speed torque of supercharging with the increased high-speed torque and power of turbocharging. The presence of the supercharger also minimizes the effects of turbo lag.

The MA10S is an engine with an electronically controlled carburetor. It was used in the Be-1 and 1982–1992 Micra (K10) and Pao. It has a hemi-head and, unusually, the spark is fired after top dead centre because of the very high flame speed in a compact engine with this head design. Compression in the {{cvt|50|PS|kW|0}} version was relatively low so that it was able to run on 90 RON petrol where available.

• Water-cooled inline-4
• Displacement: {{cvt|988|cc|L cuin|1}}
• Bore and stroke: {{cvt|68|x|68|mm|in|2}}
• Compression ratio: 9.5:1
• Maximum power (net): {{cvt|52|PS|kW hp|0}} at 6000 rpm
• Maximum torque (net): {{cvt|75|Nm|lbft}} at 3600 rpm
• 1-bbl carburettor

The MA10E was used in the Nissan Saurus Jr.

• Displacement: {{cvt|988|cc|L|1|order=flip}}
• Maximum power: {{cvt|70|PS|kW hp|0}} at 5600 rpm

The Nissan MA10ET powered the Figaro and K10 March Turbo.

• Displacement: {{cvt|988|cc|L cuin|1}}
• Bore and stroke: {{cvt|68|x|68|mm|in|2}}
• Maximum power: {{cvt|76|PS|kW bhp|0}} at 6000 rpm

• Compression ratio: 8.0:1
• Fuel supply device: Nissan Motor ECCS
• Power resource(V-AH): 12-30

The MA12S is the designation for the larger {{cvt|1235|cc|L|1|order=flip}} engine, featuring an enlarged bore as well as stroke. It was used in the Nissan Micra K10.

• Displacement: {{cvt|1235|cc|L|1|order=flip}}
• Bore and stroke: {{cvt|71|x|78|mm|in|2}}
• Maximum power: {{cvt|60|PS|kW hp|0}} at 5600 rpm
• Maximum torque: {{cvt|94|Nm|lbft|0}} at 3600 rpm
• Compression ratio: 9.0:1
