Overview
The Mitsubishi Sirius or 4G6/4D6 engine is the name of one of Mitsubishi Motors' four series of inline-four automobile engines, along with Astron, Orion, and Saturn.
The 4G6 gasoline engines were the favoured performance variant for Mitsubishi. The 4G61T powered their Colt Turbo, while the 4G63T, first introduced in the 1980 Lancer EX 2000 Turbo, a non 4g63 variant also saw service in the Sapporo and Starion coupés during the so-called "turbo era" of the 1980s, creating for itself an illustrious motorsport heritage as the powerplant under the hood of the World Rally Championship-winning Lancer Evolution. A UK-market Evo known as the FQ400 had a 400 bhp version of the Sirius, making it the most powerful car ever sold by Mitsubishi....
