you can send out a stock piston to arias and they will scan it and make a forged one for you with exact valve cut relief and you can gas port them for forced induction cars. I had a set made a while back for my turbo Porsche.
here are some photos of the pistons arias made me and then after coating.
Exactly... I get calls asking about those "CP" pistons on Ebay that are supposedly for the ISF, yet look nothing like the 2ur-gse pistons, nor do they even attempt to duplicate the crown pocket that is required for the direct injection. So I called CP and they told me that they have never seen a 2ur-gse piston, they don't make a 2ur-gse piston, and no one ever sent them a 2ur-gse piston for modelling.
That said, there are some OEM cars with forged pistons, particularly highly turbocharged 4 cylinders like the 4B11T (pistons are forged, rest of car is plastic Most of the OE forged pistons out there are made by Mahle and are 4032 alloy which is not as strong as 2600 series alloy but doesn't require as much piston to wall clearance.
The new "Voodoo" v8 in the Mustang GT500 is supposed to have forged 4032 pistons from Mahle.

Sad to see Mahle making that kind of compromise. Their racing work is truly the best. I used to have a contact there some years ago.
So who here has or done a built block on their ISF?
has any one installed forged rods, pistons, done any ported head work?
If so what was your reason for rebuilding your motor ? Seeing some nice forged pistons and rods being sold for the 2ur-gse which is what has me curious.
I called CP today, they verified that these are indeed available to any spec. He was also familiar with the engine code when I said it and confirmed two suppliers currently have orders secured with them. Hence the low pricing on ebay since I'm assuming this retailer essentially "preordered" or even contracted a set amount.
