i went to see ian last weekend and he said you was coming down and your after some more power . i run arias pistons in my engine and talking to ian he rates both highly and i know arias pistons are using in very high powered drag cars in america. cp pistons are also used in high powered cars and ian showed me a set of standard zetec turbo off the shelf pistons and a set he has custom made and to say theres a difference is a small statement , lighter , bigger pins , different sized skirts avaliable and balanced. ive never had any trouble with my pistons and these are still the orginals from around 2004. if your getting them from ian which i take it you are then the choice is yours really as both are made to ians spec.

cheers paul
