From MY understanding...
1) Singapore, and SOME areas in Europe got the high compression engines.

2) This compression difference seems to correlate to cars with, or without catalysts. Cars/engines without cats... got high comp engines, cars/engines with cats got lower comp engines.

2a) This SEEMS to be the difference between 4AGE and 4AGEC. The "C" meaning catalyst equipped


Now for some bad news... these cars are over 25 years old now... there is a fair chance that the original engine is no longer in the car... so knowing if your car was originally cat equipped may not be helpful.

If it is bone stock and from Belgium it is bound to have the high compression engine.
