I know the weight of the stock pistons. I know the weight of the HKS pistons. I also know the weight of TODA pistons, the HKS 'H' section rods and the stock rods. All I want to do is find out the weight of the JE pistons.....
Never dealt with Jun. Had LOTS of dealings with Cosworth/Arrow/Farndon in my Burton days. Very good. On par with HKS and (I presume) Jun.
