I am going to mount in my STI 2006 pistons and connecting rods forged more resistant, because it does haven´t forged pistons standard.
I have seen in JUN and Cosworth, which is more recommendable?

Also, I am mounting in my STI06 2.5T, oil cooler Spec C, Denso 280 fuel pump, STI Spark plugs, oil pump STI, Prodrive P1 Japan Competition Exhaust, Down pipe High flow CAT, IHI VF42 Twin Scroll Turbo, Motec M48 ALS/Launch Control… etc
