* 1.6L I4 engine (J16A): This engine is non-interference. This means that if the timing belt breaks, the valves and pistons will not collide, reducing the risk of major engine damage.
* 2.0L I4 engine (J20A): This engine is also non-interference.
Therefore, both engine options in the 2006 Suzuki Forenza are non-interference engines. This means that a broken timing belt is less likely to cause catastrophic engine damage. However, it's still crucial to maintain the timing belt and replace it according to the manufacturer's recommended schedule to avoid potential problems.
