Which pistons ?

[J.D.B.]

Thank you for the info, i think about it.

Another question: can i use high comp pistons in a bleu top ?

[Bean]

if the engine you're putting them into hasn't been decked too much there's no reason why you shouldn't be able to use them - even if everything else is stock (although a remap wouldn't hurt)

You might bump into some problems with the different piston wrist pin diameters... Wont work unless you use a different crank.

[J.D.B.]

Two different explanations . . .

[Bean]

ah well Ivan is right as I assume the piston are meant for your rods (guessing you have an old bluetop with 18mm pins you'd obviously need matching pistons) - else as Ivan said you'd be looking at the later setup (crank and rods with the bigger pins)

[J.D.B.]

Yes indeed, i need 18 mm pins.
