The 2.0-liter engine Toyota 1G-GZE Supercharger was produced by the company from 1988 to 1991 and was installed on such popular models as Crown S130, as well as Chaser, Cresta, Mark II X80. This power unit is essentially a slightly modernized version of the 1G-GZEU motor.

Main faults, breakdowns and problems of the 1G-GZE engine
Despite its high reliability ratings, the 1G-GZE engine has several characteristic problems and operating features:
- Compressor reliability
With regular oil changes, the SC14 compressor does not cause much trouble, but requires attention to condition and timely oil changes. - Pump.
The 1G-GZE’s most notorious problem is the unreliable and expensive pump, which often fails. - Instable idle speeds
Floating revs can be caused by a dirty throttle assembly or problems with the idle speed regulator (idle control valve). - No hydrocompensators
The engine does not have hydrocompensators, so it is important to check and adjust valve clearances regularly, every 20,000 km. - Problems after 200,000 km
After reaching the mileage of 200,000 km, ring problems may appear, resulting in increased oil consumption and the need for repair.
The Toyota 1G-GZE engine has become popular among enthusiasts due to its good power, but requires timely maintenance to maintain reliability.
Reliability facts:
- the engine is undemanding of oil (a well-known plus of the 1G, time-tested design, no hydrocompensators, VVTi, and similar designs with narrow oil channels… but I’ll stipulate that this does not apply to all versions of the 1G);
- engine is absolutely not prone to overheating, and if it happens, survives overheating relatively calmly (although how to try);
- not picky to fuel (low compression ratio);
- when the timing belt breaks, the valves do not suffer;
- discovering my old engine (340tkm) I found native chon in all cylinders.
