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- Quite a few problems here are due to the vagaries of an outdated ignition system;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.
Yes to hydraulic lifters but there was never a factory turbo of this engine. Any turbo G13B was done up by the owner. In Japan, the Cultus GTi with the G13B had more power, mostly by way of higher compression and was available with AWD though. There was a 70hp turbo of the 1.0 3 cylinder (G10) in the early years, which was also available in Canada as the Chevrolet Sprint and Pontiac Firefly Turbos.
