fox bodies(87-92) have Forged Pistons
Fox Bodies(1993 model only) have Hypereutectic (hyper-you-teck-tick) lol lil help to the people who are like wtf does that say?
Well in other words, they are not forged or 1 piece, they are cast which is the process of joining 2 pieces together at a certain point.
That certain point on them is a weak spot and will break much easier than a forged piece of metal.
It's highly advised to pick up an 87-92 and skip the 93 unless your not gonna race it because its not gonna like nitrous to much lol...
