Pure Motorsport Pistons for PM240 Engine

* Required Fields

Excl. Tax: £640.00 Incl. Tax: £768.00

Very high quality forged pistons, custom made exclusively for Pure Motorsport in the USA by CP Carrillo  As used in our PM240 engines.  

 Custom CP X Bridge pistons, three ring, 20mm pin and crown height to suit our con-rods, 82.7mm or 83.0mm


Due to the reduced crown height of these pistons they do not fit with standard con rods - they must be used with our PM240 con rods.

The crown shape is also designed to suit our cylinder PM240 cylinder heads - they don't fit with standard combustion chamber shapes so you will either have to modify your combustion chamber to suit or use with one of our cylinder heads.


Generally off the shelf pistons will have large valve cutouts to allow for the use of big valve lift cams - this lowers the compression ratio so the intruder dome height will be higher to compensate.  Off the shelf piston domes will be designed to fit the standard combustion chamber so take up a smaller area - the intruder needs to be higher still to raise the compression ratio.  The higher the dome is, the more of a barrier it produces to the flame front within the combustion chamber, so the lower the intruder height - the better!
We custom design our pistons to suit this engine configuration, so we don't have any compromises - we also use a superior quality manufacturer of our pistons by the name of CP Carillo in the USA.


The 82.7mm pistons are not supplied with piston rings - please click here.

The 83.0mm pistons are supplied with CP ring packs hence the extra price.
