Hi people,

I was wondering if i could get the following information. I am in the process of getting customs pistons and conrods from cosworth racing in the uk.

Could someone post the OEM piston/conrod dimension. Or if someone has dimensions of their custom pistons/conrods they can post their dimension here to share.

Cosworth racing requres a fair amount of details before the production of the custom conrods and pistons, so i need a starting point.

I haven't taken apart my engine yet, so that's why i'm requesting information here on the forum.

Any help would be much appreciated.

"Actually it's:
PCX (2.0L) 153.00mm
PZX (2.2L) 149.65mm

For pistons there are too many dimensions/shapes that matter. They are probably going to need a piston in hand.

 

I have used pistons and rods. I could send them one piston and one rod if you would like.

If you're increasing the compression ratio and running a very high lift camshaft they may need a mold of your combustion chamber and the "Cam Doctor" data from the camshaft.
