The 2.0-liter Hyundai Kia G4CP engine was produced in Korea from 1988 to 2003 under license and was essentially a clone of the Mitsubishi 4G63. Such a unit was installed on the Grandeur, Sonata and Joice. Two versions of the motor were produced: for 8 and 16 valves, the latter has its own index G4CP-D or G4DP.
Sirius family: 1.6 L – G4CR; 1.8 L – G4CN, G4CM, G4JN; 2.0 L – G4CP, G4JP; 2.4 L – G4JS, G4CS.
The engine was installed on:
- Hyundai Grandeur 1 (L) in 1986 – 1992; Grandeur 2 (LX) in 1992 – 1998;
- Hyundai Sonata 2 (Y2) in 1988 – 1993; Sonata 3 (Y3) in 1993 – 1998;
- Kia Joice 1 (RS) in 1999 – 2003.

Disadvantages of the Hyundai G4CP engine
- The main problems of the engine are associated with the low resource of the timing belt and balancer belt.
- A break in any of these belts usually ends up with valves and pistons meeting.
- Hydraulic lifters do not like bad oil and can knock even up to 100,000 km.
- Often there are floating idle speeds due to throttle contamination.
- Still here, the engine mounts serve quite a bit and the exhaust manifold often cracks.
