    Forged pistons won't take what broke the original ones either. Mapping? What happened, piston melted? Or ring lands broken?

    piston has melted, its common when running over 1 bar on un-forged pistons.

    bullsh1t, its the same bottom end as the 200, just the head is different. And ive seen lots of people running over 400hp @1.4 bar on standard unopened engines as drift cars that spend every second being driven like it was stolen. Its the map that is the flaw hear, like pete has mentioned

    its not the same bottom end as far as i know, people keep telling me i shouldnt of ran 1.2 bar on unforged pistons

    pulsar has much weaker pistons than the 200

    i thought the pulsars were lower compression than the 200's, so boost shouldnt be an issue

    pulsar should be ran as a max of 1 bar on standard engine.
