4G92 mV0F^5
Q^4j
The 4G92 displaces 1.6 L (1597 cc). First appeared in late 1991 Japanese spec Mirage RS and Super R in DOHC form, it is basically bored out to 81 mm and tuned version of the 4G91 producing 145 hp (108 kW). Later was introduced fuel-efficient SOHC version. But 4G92 is best known of its high-performance MIVEC equipped DOHC version, which fully replaced "ordinary" DOHC in 1993. Power output raised as high as 172 hp (128 kW), as found in the Mirage Cyborg-ZR and JDM ’92 Lancer MR, making it one of the most powerful 1.6 L N/A engines. A Modular Displacement (MD) version of the 4G92 MIVEC was also produced – MD is Mitsubishi's cylinder deactivation system which helps improve fuel consumption. C72?vAc,F
