That is a huge misconception. Manufacturing processes have improved in the last few years with huge improvements at gravity die casting which regular pistons and internal components are at. High compression engines like the MK3 pistons which are high compression are also forged or die cast using modern methods. A regular die cast piston or rods at high compression would suffer serious cracking at those high internal Temps and pressures. Ford and most companies market "forged" to trick those who don't know about manufacturing methods or processes.That is yet to be seen, but mathematically-speaking I would have to assume that would probably require new rods to be reliable. The FoST rods tend to let go between 440-470 whp, which is roughly double the stock OEM whp (230-ish). And those are forged rods.
With the Mk3 putting down roughly 150 whp stock, doubling the power output is probably not going to be 'reliable'. The community is not going to know without a few examples getting to that mark first, obviously.
