Mitsubishi 4N1 engine
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 Galant, 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; 406 PS (400 bhp) 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 1,595 cc (1.6 L) with bore/ full length stroke of 82.3 mm × 75 mm (3.24 in × 2.95 in). 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.
- 4G61 105 hp (78 kW; 106 PS) at 6100 rpm.
- 4G61T (USA/Canada only) 135 hp (101 kW; 137 PS) at 6000 rpm and 191 N⋅m (141 lbf⋅ft) of torque at 3000 rpm.
- 4G61T (Japan) 145 hp (108 kW; 147 PS) at 6000 rpm and 220.65 N⋅m (163 lbf⋅ft) of torque at 2500 rpm.
The larger 1.8 L 4G62 was an SOHC 8-valve unit for longitudinal rear-wheel drive and all-wheel drive use. With a bore and stroke of 80.6 mm × 88 mm (3.17 in × 3.46 in), it displaces 1,795 cc (1.8 L). 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 1,997 cc (2.0 L) version.
Bore x stroke is 85 mm × 88 mm (3.35 in × 3.46 in) 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; 197 bhp) JIS gross were claimed - the output claims later shrank to 170 PS (125 kW; 168 bhp) - 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; 93 PS) at 5500 rpm in European trim (1989). The SOHC version was also used in Mitsubishi Galant models until 1993. It has 76 kW (102 bhp; 103 PS) of output and 157 N⋅m (116 lbf⋅ft) 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 2.0 L 2-door Pajero with an output of 101 kW (137 PS; 135 bhp) at 4700 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; 99 bhp), 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 202 kW (271 bhp; 275 PS) at 6500 rpm with 370 N⋅m (273 lb⋅ft) 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, G63T (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 for these engines. This engine was also used in a special McLaren F1(Known as McLaren F1 EVO).

Turbocharged version of the 4G63. ACL bearings lists the differences in journal lengths between different years of production, and whether or not it used a thrust bearing on the number three journal or thrust washers. There was a 2V and 4V 4G63T engine.
The 4G64 is the second largest variant, at 2,351 cc (2.4 L). Early models were 8-valve SOHC, but a later 16-valve SOHC and DOHC version was also produced. All used MPFI and had an bore and stroke of 86.5 mm × 100 mm (3.41 in × 3.94 in). The 4G64 was later also available with gasoline direct injection. Output varies between 140 hp (104 kW; 142 PS) at 5,250 rpm with 161 lb⋅ft (218 N⋅m) of torque at 4,000 rpm in the Mitsubishi L200 and 152 hp (113 kW; 154 PS) at 5,500 rpm with 162 lb⋅ft (220 N⋅m) of torque at 4,000 rpm in the Chrysler Sebring/Stratus. The Chrysler version features fracture-split forged powder metal connecting rods. The DOHC and SOHC 16V 4G64 are interference engines, while the SOHC 8V 4G64 is a non interference engine. From March 1996 an LPG version with 115 hp (86 kW; 117 PS) at 5,000 rpm was available in the Mitsubishi Canter.

Known as the "Sirius Diesel", the 4D65 had the same dimensions as the 4G62 1,795 cc (1.8 L). It was available either naturally aspirated or turbocharged (with an air-to-air intercooler), and was used in most Mitsubishi diesel passenger cars in the eighties and beginning of the nineties. It was developed specifically to be transversally installed in front-wheel-drive cars, unlike the preceding 4D5-series which remained in production for commercial vehicles. The 1.8 TD power figures were comparable to those of the 22% larger 2.3 TD 4D55, with more low-down torque and while being much smoother. The cast-iron block was typical for Mitsubishi, but unusual for diesel engines, in being equipped with balance shafts. A number of installations combined this engine with four-wheel-drive. Some period critics were doubtful of the durability of the turbocharged engine, as the charger would spool up immediately (many turbodiesels have a thermostat which only allows the turbo to engage once the engine has warmed up) and a very short pre-heating period, leading to lots of noise and smoke in cold weather starts.

Known as the "Sirius Diesel", the 4D68 version displaced 1,998 cc (2.0 L). It was fitted with a 93 mm (3.66 in) stroke crankshaft and the cylinder bore diameter was 82.7 mm (3.26 in). This engine used pistons with a static compression ratio of 22.4:1 and piston pins were 25 mm (0.98 in) OD. It was available either naturally aspirated or turbocharged, and replaced the 4D65 as Mitsubishi's "go-to" diesel.

The 4G69 is a 2,378 cc (2.4 L) version built in Shiga, Japan and Shenyang, China. Bore and stroke is 87 mm × 100 mm (3.43 in × 3.94 in). Output is 120 kW (161 hp; 163 PS) at 5750 rpm (160 in the Sportback Wagon) with 219 N⋅m (162 lb⋅ft) of torque at 3500 rpm. It has a cast iron engine block (later switch to aluminum block) and an aluminum SOHC cylinder head. It uses multi-point fuel injection, has 4 valves per cylinder with roller followers and features forged steel connecting rods, a one-piece cast camshaft, and a cast aluminum intake manifold. The 4G69 incorporates Mitsubishi's MIVEC Variable Valve Timing technology.
Mitsubishi ceased any further development and production of Sirius engine after 2012 model year, and its joint-venture, Shenyang Aerospace Mitsubishi Motors Engine Manufacturing Co., in China is now the only one producing 4A9 engines (improved to aluminum block while adding timing chain) for the Chinese market.
