4G63
The 4G63 was a 1997 cc version. (85mm Bore x 88 mm Stroke) SOHC and DOHC were produced. The DOHC version was introduced in 1987 in the Japanese market Galant VR-4 and came turbocharged or naturally aspirated. It is found in various models including the 1988-92 Galant VR-4 and the U.S. market 1990-1999 Eclipse.
The SOHC version was used in Mitsubishi Galant models until 1993. It has 76 kW of output and 157 NM of torque at 4750 rpm.
Also the SOHC version is produced until the late 90s and early 2000 and it is used in Mitsubishi cars like the Montero and the 2.0L 2-door Pajero with an output of 101kw at 4700 rpm.
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 beefier rods and the use of 6 bolts to secure the flywheel to the crankshaft; May 1992 to 2006 Evolution versions have lighter rods and use 7 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 Japanese/US Mitsubishi Lancer Evolution is 271 hp (202 kW) at 6500 rpm with 273 ft·lbf (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 4 valves per cylinder, is turbocharged and intercooled and features forged steel connecting rods. With the release of the Lancer Evolution IX ( 286 hp @ 6500rpm, 289ft*lb of @ 3500rpm, 7000 rpm redline), it has received Mitsubishi's MIVEC variable valve timing system, which gives smoother power delivery and a flatter torque curve.
In the United Kingdom, a special Lancer Evolution, the FQ-400, produces 302.13 kW (405.2 hp), from a 4G63 engine. At 202.6 hp (151.3 kW) per liter, it has possibly the highest specific output per liter of any production engine.
[edit] Racing
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 sequential WRC championships in his lancer
