    got a reciept for the headgasket? check what size that is? its definatley not an acurate way of telling but i shouldnt imagine it would be a thick one if it isnt forged? personaly wouldnt have bought it as a forged engine without some kind of proof mate.

    see loads advertised as forged when most of them arent. its an easy thing to say it has as its hard to prove.

    Take it to a garage that has a bore cam (a long bendy camera that will go down the spark plug hole) you should be able to tell from the shape of the top of the piston. You can even go as far as going into the oil return into the sump for the turbo to see the rods. That would be the easiest way to do it.

    Every tuning company should have a bore scope, some garages might also have them.
    Whip the sump off when you next do an oil change ;)

    How can you tell it has forged pistons by taking the sump off? I get you can tell if the rods are but the pistons too?

    Wouldnt you have to take a whole one out?

    You can see the underside of the pistons and thats where the manufacturers numbers usually are.

    Also the piston tends to be thicker on forged pistons where the gudgeon pin goes through the piston and flat bottomed with a machined finish were as the standard ones are just cast.
