hello. recently i had a valve drop on my renault clio 200 and it damaged one of my pistons and i found that i have a megane turbo block with the code number of f4k 787 written on the block. i cant find pistons or engines anywhere in my country so im looking for other renault pistons that are non turboed that will fit into my megane 2.0 turbo block. i need help on which OEM non turboed pistons i could fit into this block. thanks
