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 Galant VR-4 and the U.S. market 1990-1999 Eclipse, as well as 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 Ram50, etcetera) 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.
In 1998 Hyundai with help from its partner Mitsubishi used a 4G63 cylinder head and mated it to a 4G64 block to make its new 2.4 liter engine to power the 1998 to 2005 Hyundai Sonata and 2000 to 2005 Kia Optima. The engine is referred to as the G4JS in Hyundai nomenclature.

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 beefier 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.
