MITSUBISHI 4G93/4G93D COMPLETE ENGINE

The 4G93 is a 1.8L (1834 cc) engine available in both SOHC and DOHC versions. Turbocharged variants are also produced. In mid 1996 Mitsubishi released a gasoline direct injection (GDI) version of the 4G93. This GDI model saw a production of over a million units though it was a heavy polluter therefore only sold in the Japanese market. A partially cleaned up version (with less power) was later sold in Europe, and was among the first of the modern GDI engines. It suffered from poor fuel economy and engine life.
