if he's saying STOCK internals, then yeah I call BS too, dont think he specified though, on looking at the pictures though those do look like cast pistons...but so can forged with a thermal coating on top....I tend to assume anyone who adds an turbo to a non turbo engine does the job right and rebuilds forged...which I know most dont do...they think spending $3000+ on a turbo kit is fine, but cant take the expense of an extra $800 for some forged pistons and rods? it doesnt make much sense to me to turbocharge a stock engine when forged stuff isnt much more expensive(unless your the junkyard turbo kinda person, then it makes sense)
