The Suzuki G13B 1.3-litre petrol engine was produced in Japan from 1986 to 1995 and was used in powered versions of the Swift GTi and the similar Cultus GTi in the first two generations. Many confuse this DOHC unit with its SOHC counterpart G13BB, which was installed on the Jimny.
Engines of the G-series: G10A, G13B, G13BA, G13BB, G15A, G16A, G16B.

Disadvantages of the Suzuki G13B engine
- The main thing is not to allow the motor to overheat, then it will serve for a long time and without problems;
- Overheating cracks the cooling jacket of the aluminum block, and sometimes the cylinder head;
- Also, the exhaust manifold often bursts, but it is quite possible to brew it;
- Quite a few problems here are due to the vagaries of an outdated ignition system;
- It does not have hydraulic lifters and the valve clearance needs to be adjusted every 30,000 km.
the g13b dohc (pictured) does have hydraulic lifters. It also did come with a turbo in japan.
