Mitsubishi Sirius engine
|Cylinder block alloy||Cast iron|
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 [WET World Eagle Talon], went on to see service in the Sapporo and Starion coupés during the so-called "turbo era" of the 1980s, before 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 298 kW (405 PS) version of the Sirius, making it the most powerful car ever sold by Mitsubishi.
The 4D6 diesel engines supplemented the larger 4D5.
The 4G61 displaces 1595 cc (82.3 x 75.0 mm bore/ full length stroke). This engine was always DOHC 16-valve and used either Multi-point (MPFI) or Electronic Control (ECFI) fuel injection. A turbocharged version was also produced for the Mirage and Lancer. The 4G61 does not have balance shafts like the other 4G6x motors.

The larger 1.8 L 4G62 was an SOHC 8-valve unit for longitudinal rear-wheel drive and all-wheel drive use. With an 80.6 x 88.0 mm bore and stroke, it displaces 1795 cc. It was available either in carburetor form, multi-point fuel injection, or ECI Turbo as found in the Lancer EX 1800GSR or 1800GT, and Cordia GSR.

Turbocharged version of the 4G62.
The 4G63 was a 1997 cc version.
(85 mm bore x 88 mm stroke) SOHC and DOHC were produced. Both versions were available in either naturally aspirated and turbocharged form. For front-wheel drive applications, the turbocharged Sirius' name was changed to "Cyclone Dash". As fitted to the fifth generation Galant 200 PS (147 kW) JIS gross were claimed - the output claims later shrank to 170 PS - for the turbocharged and intercooled "Sirius Dash 3x2 valve" engine. This version could switch between breathing through two or three valves per cylinder, to combine high top-end power with low-end drivability as well as allowing for economical operation. It was a modification of Mitsubishi MCA-Jet technology which used a secondary intake valve to inject air into the engine for more efficient emissions control. The DOHC version was introduced in 1987 in the Japanese market Galant, and came in turbocharged or naturally aspirated form. It is found in various models including the 1988-92 Mitsubishi Galant VR-4, the U.S. market 1990-1999 Mitsubishi Eclipse, and the Mitsubishi Lancer Evolution I-IX. Later versions also received Mitsubishi's variable valve-timing system, MIVEC.
A SOHC carbureted eight-valve version (engine code G63B) was also available in Mitsubishi's pickup trucks (L200, Strada, Mighty Max, Dodge Ram 50) from the eighties until the mid-nineties. It produces 92 hp (69 kW) at 5,500 rpm in European trim (1989). The SOHC version was also used in Mitsubishi Galant models until 1993. It has 76 kW of output and 157 Nm of torque at 4,750 rpm.
Also, a SOHC version was produced until the late 90s and early 2000s and was used in Mitsubishi cars like the Montero and the 2.0L 2-door Pajero with an output of 101 kW (137 PS) at 4,700 rpm. Also the N33 and N83 Spacewagon and Galant (UK market) received the 4G63, in single-cam sixteen-valve format. A similar version, with 100 PS (74 kW), was also used in some light duty Mitsubishi Canters from 1997 on.
The Mitsubishi Eclipse, Eagle Talon and Plymouth Laser introduced the DOHC turbocharged intercooled version to the U.S. in 1989 through Diamond Star Motors, a joint venture between Mitsubishi Motors and the Chrysler Corporation. From 1990 to late April 1992 came thicker connecting rods and the use of six bolts to secure the flywheel to the crankshaft; May 1992 to 2006 Evolution versions have lighter rods and use seven bolts to secure the flywheel to the crankshaft. They are referred to as the "six bolt" and "seven bolt" engines, respectively.
Output for the 2003 US Mitsubishi Lancer Evolution is 271 hp (202 kW) at 6500 rpm with 273 lb·ft (370 N·m) of torque at 3500 rpm. It has a cast iron engine block and aluminum DOHC cylinder head. It uses multi-point fuel injection, has four valves per cylinder, is turbocharged and intercooled and features forged steel connecting rods.
The final version of the engine was found in Lancer Evolution IX. It was equipped with Mitsubishi's variable valve timing system, MIVEC. This version also had a revised turbocharger, extended reach spark plugs, two-piece rings.
Its turbocharged variant, 4G63T (also sometimes referred to simply as the 4G63), has powered Mitsubishi vehicles in World Rally Championships for years in the Mitsubishi Galant VR-4, Lancer Evolution, Carisma GT, and Lancer WRC04. It was the powerplant of the Lancer Evolution when Tommi Mäkinen won his four consecutive WRC championships in his Lancer. MHI and T-4 turbos were both used as power plants for these engines.
