Can anyone tell me what type ,make and size pistons are used for the 2.1 zetec conversion. I have heard 86mm pistons are used but this only takes the block up to 2045cc 55cc short of 2.1. I think im right in hearing its a vauxhall piston which is used but not sure which one can anyone help?

 

calibra turbo items methinks.

 

It is the vauxhall piston that is used. 86mm standard size. This gives you the 2045cc but most people refer to it as 2.1
