The Sirius family of engines are 4 cylinder in line engines from 1.6 to 2.4 Litres in capacity. They are designated with 4G6x numbering. All engines except the 1.6L feature balance shafts. All engines have belt-driven camshafts.

Within the same engine model (e.g. 4G63) there can be numerous variations, these include:
*Single Overhead cam with 2 valves per cylinder
*Single overhead cam with 4 valves per cylinder
*Double overhead cam with 4 valves per cylinder
*[[MIVEC]] technology
*Turbocharged versions

==4G61==
The 4G61 is a 1.6 litre engine. It is the only Sirius engine not to have balance shafts. The 4G61 was only available as double overhead cam with 16 valves. All versions were fuel injected. A turbocharged version was produced for the Mitsubishi Mirage.

There are two variations of this engine, one version uses a 77.96mm x 86.1mm bore and stroke while the other uses a 82.29mm x 74.93mm bore and stroke.

In Australia the engine was used in the CB Lancer.

==4G62==
The 4G62 is a 1.8 litre engine displacing 1795cc. The engine was not only used by Mitsubishi but also sold to Hyundai for use in the Lantra.

The Mitsubishi branded engine was only produced in single overhead cam 8 valve form. It was intended for rear-wheel drive application. All versions of this engine were fitted with a carburettor.

Mitsubishi Cordia GSR came from the factory as a turbo charged 4G62 8 valve SOHC. It was available in Australia from 1983-1989. The valve covers are marked Sirus Turbo. The cordia uses throttle body fuel injection( 2 injectors). The engines utilised a TC06 or later a TC05 turbo. http://www.cordiapower.com

The Hyundai branded engines came in two forms - a single overhead cam version which was the same as the Mitsubishi branded engine. This was known as the G4CM. The second variant was a double overhead cam unit which had a slightly different bore (81.6mm) and displaced 1836cc. This was labeled the "G4CN".

In Australia the engine was used in the Mitsubishi L300, Hyundai Lantra and Cordia GSR.

==4G63==
The 4G63 is probably the most well-known in the Sirius family as it is the engine used in the Evolution Lancer. The 4G63 is a 2.0 Litre engine displacing 1997cc.

The 4G63 is also the engine in the family with the most variants. It comes in two block variants - one with a 85mm x 88mm bore and stroke (used in passenger cars) and another with a 84mm x 90mm bore and stroke used in commercial vehicles. It also comes with 4,6 and 7 bolt mains making switching between variants difficult.

The 4G63 is also available in single overhead cam with 8 valves and double overhead cam with 16 valves. When used in the VR-4 Galant and Evolution Lancer it is fitted with a turbocharger.

Depending on the application the 4G63 is fitted with a carburettor or fuel injection.

As of the 2006 model year, the 4G63 has another variant - the 4G63 with MIVEC and turbocharger which will be fitted to the Evolution IX Lancer.

A special version of the 4G63 released in 1983 called the "Sirius Dash" was the world's first 2x3 valve engine. This engine featured the usual one inlet and one exhaust valve but at above 2500rpm a second inlet valve was opened electronically to allow more fuel in.

The 4G63 was also used by Hyundai and is labelled "G4CP". Both the single overhead cam (2.0S) and double overhead cam (2.0D) were used).

In Australia the 4G63 has been fitted to:
*SOHC - Mitsubishi Galant, L300
*DOHC - Galant GSR, VR-4, Hyundai Sonata

==4G64==
The 4G64 is a 2.4 Litre engine displacing 2350cc. This is the 4 cylinder engine that was used in the [[TE]] and [[TF]] Magna (see [[Sirius]] for more information).

These engines had a 86.5mm x 100mm bore and stroke and were only ever produced with fuel injection. Three variants were produced - a single overhead cam 8 valve, double overhead cam 16 valve and single overhead cam 16 valve.

The 4G64 was also used by Hyundai and Kia labelled as the "G4JS".

In Australia the 4G64 was fitted to:
*SOHC - Mitsubishi Express, L300, Starwagon, Nimbus, Triton
*SOHC 16v - Mitsubishi Magna TE/TF, Express, Starwagon
*DOHC - Hyundai Sonata, Hyundai Santa Fe, Kia Optima

==4G67==
The 4G67 was a 1.8 litre engine displacing 1837cc. It was only ever produced as a double overhead cam fuel injected unit.

I am not aware of any Australian Mitsubishis that were fitted with this engine.

==4G69==
The 4G69 is the newest member of the siruis family, being introduced in 2004. It is a revised version of the 4G64 SOHC 16v.

As with the 4G64 SOHC 16v it is a 2.4 litre single overhead cam unit with 16 valves, has roller rockers and a one piece cast camshaft. Where it differs from the 4G64 is that it has a slightly larger displacement (2374cc) and all feature [[MIVEC]] technology.

In Australia the 4G69 has been used in the Mitsubishi Outlander and Grandis.
