The Nissan MR16DDT is a 1,618 cc, inline‑four turbocharged petrol engine produced between 2010 and 2020. It features a DOHC, 16‑valve design with direct fuel injection and variable valve timing, delivering a blend of efficiency and spirited performance. Peak output ranges from 140 kW (190 PS) to 162 kW (220 PS), with torque figures between 240-250 Nm, making it ideal for sporty compact and crossover applications.
Fitted primarily to the Juke NISMO, Pulsar, and Qashqai, the MR16DDT was engineered for drivers seeking agile acceleration and responsive handling. Its driving character is defined by strong mid-range pull and a linear power curve, enhanced by its twin-scroll turbocharger for minimal lag. Emissions compliance was achieved through precise direct injection and exhaust aftertreatment, meeting Euro 5 and Euro 6 standards depending on model year.
One documented concern is carbon buildup on intake valves, a common trait of direct injection engines, which can lead to rough idle and reduced performance. This issue, referenced in Nissan Technical Bulletin NTB13-098, is inherent to the fuel system design. In 2016, Nissan introduced minor ECU calibrations to optimize fuel trims and combustion efficiency.
Production years 2010–2014 meet Euro 5 standards; 2015–2020 models meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/8901).
The Nissan MR16DDT is a 1,618 cc inline‑four turbocharged petrol engineered for sporty compacts and crossovers (2010-2020). It combines direct fuel injection with a twin-scroll turbocharger to deliver responsive power and competitive fuel economy. Designed to meet Euro 5 and Euro 6 standards, it balances performance with modern emissions requirements.

The twin-scroll turbo provides strong mid-range torque ideal for overtaking but requires premium unleaded (95 RON min.) to prevent knock under boost. Nissan 5W-30 synthetic oil is critical for protecting turbo bearings and the timing chain. Extended oil change intervals can accelerate carbon buildup on intake valves. The direct injection system demands periodic induction cleaning (every 60,000 km) to maintain optimal airflow and prevent misfires. Post-2016 models feature revised ECU maps for improved emissions and fuel economy.
Oil Specs: Requires Nissan 5W-30 synthetic (API SN/ILSAC GF-5) (Nissan SM-MR16). Extended drain intervals void warranty.
Emissions: Euro 5 certification applies to 2010-2014 models; Euro 6 for 2015-2020 (VCA Type Approval #VCA/EMS/8901).
Power Ratings: Measured under SAE J1349 standards. Peak output requires 95 RON fuel (Nissan PT-2018).

The Nissan MR16DDT was used across Nissan's compact platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Juke NISMO for track use-and from 2016 the facelifted Pulsar models adopted revised ECU calibrations for Euro 6 compliance, creating minor software differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface on the front of the cylinder block, near the alternator (Nissan SM-MR16). The 8th VIN digit for MR16DDT-equipped vehicles is typically 'M'. Visual identification: DOHC 16-valve head with a prominent twin-scroll turbocharger and direct injection fuel rail. Critical differentiation from the naturally aspirated MR16DE: MR16DDT has a turbo, intercooler, and higher-pressure fuel system. Service parts are generally compatible across all model years, though ECU software varies by application and model year.
The MR16DDT's primary reliability risk is carbon buildup on intake valves, inherent to its direct injection design. Nissan internal data indicated this was a common cause of drivability complaints, while its robust mechanical design otherwise proved very durable. Neglecting induction cleaning makes adherence to the OEM maintenance schedule critical.
