Not sure who sells them pre-made for our specs, but virtually any company will make you custom rods and pistons if you send them a stock one to copy. Custom forged pistons are probably $600 a set and custom rods can vary heavily depending on specs (H-Beam, I-Beam, A-Beam, manufacturer, material, rod bolts, etc) but are likely $600-$800 for a premo set.
Carrillo makes amazing connecting rods and Ross Racing and Wiseco make strong forged pistons. You should consider though that the engine needs to be rebalanced very precisely since the rotating mass is changing from factory and the redline is quite high.
