Thanks!
The engine is non turbo.

If I understand correctly -
this is post '86 piston
and this is pre '86

So at the catalogue I foud two types of pre '86 pistons:
1
In-line engine, fuel,
CVH, LRB, EFI
1597 cmі,
77/84 kW (105/115 PS)
9,5:1
injection,
Vehicle:
Escort RS, Escort XR 3i
Orion, Fiesta XR 2i

2
In-line engine, fuel,
CVH
1598 cmі,
66 kW (90 PS)
8,5:1
injection,
catalyser,
Vehicle:
Escort XR 3i, Orion

They have the same dimensions, but different compression ratios and catalogue numbers... I'm confused...
Which one I need to install?
