At that age it'll be the Pre-PD engines, red I should indicate its the 110bhp version, same as in the VAG group cars of the time.
I had my Octavia 110 remapped to 140bhp, did make it go better, then it killed the clutch and DMF. Replaced it with a solid flywheel conversion and it was mint. 4 up round the ring, full of lugagge etc etc. Used to average about 51mpg after mapping
