The first in the range of Mitsubishi 4G9x engines is the 4G91 which uses a 78.4mm bore and 77.5mm stroke for a total displacement of 1.5 litres. With a 9.5:1 compression ratio and DOHC, four-valve-per-cylinder head and multi-point EFI, this engine puts out a creditable 84kW at 6000 rpm and 135Nm at 5000 rpm on normal unleaded fuel. The engine can be found in the Japanese market ’91 top-line Lancer and Mirage/Mirage Asti. A low output carby version was also produced but it’s not likely you’re interested in that... Both engines are designed for transverse mounting and are available with a four-speed auto or five-speed manual ‘box. Most examples are front-wheel-drive but, curiously, an all-wheel-drive carby version was also produced. This engine lasted only until the mid ‘90s.
