G10

The G10 is an inline 1.0 liter 3 cylinder engine utilizing aluminum alloy for the block, cylinder head and pistons — is equipped with either a carburetor or electronic fuel injection and was also offered with a IHI RHB31/32 turbocharger and MPFI. It has a single overhead camshaft driving six valves.

A 2.91 in (73.9 mm) bore and 3.03 in (77 mm) stroke give the engine a total of 1.0 L (993 cc/60 in³) of displacement. It produces 48 hp (36 kW) at 5100 rpm and 57 ft·lbf (77 N·m) at 3200 rpm with 9.5:1 compression in the carburated model, 55 hp (41 kW) at 5700 rpm and 58 ft·lbf (79 N·m) at 3300 rpm in the fuel injected model.

From 1984 to 1988 the standard G10 engine used a hemispherical head carbureted design with mechanical lifters. From 1989 to 2001 the engine received updates in the form of throttle body injection and hydraulic lifters. A detuned 49 hp (37 kW) unit, with a slightly different camshaft, 2-ring pistons and differently tuned engine control unit, was used in the ultra-fuel-efficient Geo Metro XFi model, which delivered as much as 58 miles per gallon.

Through the 1987-1991 model years a turbocharged MPFI version of the G10 was offered. This engine delivered 73hp@4500 rpm and 115lbs/ft@3500 rpm. This turbocharged engine, with mechanical lifters, was available in both the US and Canadian Firefly/Sprint/Forsa from 1987-88. Only the Canadian Firefly/Sprint had this option, with hydraulic lifters, in the 1989-1991 model years.

As is inherent in the physics of the straight-3 engine, the G10 tends not to idle as smoothly as other engines such as a straight-6 engine.

Applications:

  • 1985–2001 Suzuki Cultus and global nameplate siblings: Chevrolet Sprint, Geo/Chevrolet Metro, Pontiac Firefly, Suzuki Swift, Suzuki Forsa
  • November 1984– Suzuki Cultus AA41S AB41S
  • 1988– Suzuki Cultus AA44S AB44S

G13

The G13 is an in line 4 cylinder engine utilizing aluminum alloy for the block, cylinder head and pistons. Displacing 1.3 L (1298 cc/79 in³), fuel delivery is either through a carburetor, a single point fuel injection or a multi-point fuel injection.

The engine was produced as either an 8 or 16 valve with a single overhead camshaft (G13A) or as a 16 valve with double overhead camshafts (G13B).

G13A

The SOHC G13A was used in the following vehicles:

G13B

The Swift GTI twin cam 16 valve (G13B) engine is well known, it used the older distributor driven off the intake cam shaft, and produced approximately 100hp(74kW)@6500rpm/83ft·lb(112Nm)@5000rpm. The North American models also had their redline dropped to 7400 rpm while in the rest of the world redline was 8000rpm.

The DOHC G13B was used in the following vehicles:

G13BA

The SOHC 8-valve G13BA was used in the following vehicles:

The engine has single-point fuel injection system delivering 50 kW (68 HP).

G13BB

The SOHC G13BB has electronic MPFI Multi-point fuel injection, generating 56–59 kW (75–79 hp) at 6,000 rpm and 104–115 N·m (77–85 ft·lbf) at 4,500 rpm. The G13BB has 2 double coil packs directly bolted on the valve cover, although early models still had the coil packs mounted to the left side of the head, traditionally where the distributor was located. This engine, unlike the G16 series uses a MAP sensor to monitor manifold pressure. This engine uses the same G series block found in many other suzuki models and therefore is quite a popular conversion into the Suzuki Sierra 4wd, which runs either a G13A(85-88) or G13BA(88.5-98). This allows the physical fitting of the engine into the engine bay quite simple as engine and gearbox mounts are identicle and both engines are mounted north-south.

Applications:

G13K

The DOHC G13K was used in the following vehicles:

G15A

This engine is a 1.5L 16-valve (SOHC).

Applications:
