whats the best to go for and how much?? also on a standard 1.6 what size do I need to get because I see they have differences of 1.5 and 1mm in height.

How much do I get skimmed off to get the best compression which is?? and who does skimming?

thanks

 

ive never baught pistons before 'but i will be soon' but if i did i dont think once they get here you have to send them to get skimmed as they should be ready just to be banged in so to say i also think im going for JE pistons myself or wiseco

 

The 1mm/1.5mm is usually the re-bore diameter!

 

good pistons will be unfinished crown so they can be machined to the correct CR. My cosworth racing pitons had 2.5mm machined off.

 

oh, so do they sell the normal size forged pistons or do I have to get a re-bore?

Got a link for the cosworth racing pistons??

cheers

 

cosworth racing don't make them for the CVH anymore They were a one off batch.

 

I've just got my hands on some for my 1.6 lump...

secondhand obviously

There you go available in 80 80.5 and 81 mm

also they give standard comp ratio come with rings and are finished..

 

Or you could get a custom made piston that wouldn't need skimming or anything.
