they have the same crank,but diffenent rods and pistons.
Earlier 3sg pistons have a lower crown hight than the 4gen altezza 3sg, so gt4 bits will not do me as for 1 there a turbo engine and mine is na and staying na and 2 the na pistons are diffenent.
As said above i'm looking for gen4 altezza 3sge forged pistons and arp rod bolt kit
