Nice choice of engine even if your 'nic' belongs to the opposition! The forged internals of the 03 Cobra are great. The standard manley rods and forged pistons seem to take the boost really well. With a compression ratio 0f 8.5:1 it ain't hard to wind her up. I have heaps of information on your engine if yo want it. Be aware that I wish I never found it.
