Duratec 2.0/2.3L SBD/Omega Piston 87.50mm Set with Rings
We supply this version of Duratec 87.50mm bore piston, which come complete with rings for those people who are using a secondhand engine. The pistons will come with the rings unfitted as the rings must be gapped when fitting. They come as a set of 4, but may also be available singly on request depending on stock levels.
Our compression ratio figures are based on using a standard height block, with a standard Ford head gasket, and are only relevant for a 2.0L engine (83.1mm stroke crank).
11.7:1 with a standard cylinder head (circa 42.0cc chamber volume)
12.3:1 with a machined cylinder head (circa 40.0cc chamber volume)

The Omega pot type pistons are extremely high quality and SBD have used them since we first started. The piston crown has been developed over time to what we believe is the best pot type piston available, if fact in many up against other makes of piston, they regularly out perform even those types which are supposed to be a slipper type. If you have a reasonable budget which is not able to stretch to our high specification Omega slipper pistons, choosing our Omega Pot type piston is an essential way to gain performance and reliability at the right price.
You can change the compression ratio of your engine by skimming the cylinder head if you wish to increase the compression. On the pot type pistons, you can lower the compression by machining the intruder part of the piston down (pot type pistons can have their intruder machined down to the deck of the piston if required).
