OK so on top of new pistons, rods, oil pump, all gaskets and seals. 1. I'm also looking at getting a new intake manifold, From what i've read you only really see gains in the higher rpm range, Is this true? And if it is i guess it would be pointless on a boosted ls that doesn't plan on going over 8k. 2. Ignition? Should i go with an after market setup or will my stock ignition hold true to 300whp? 3. Will a GSR water pump fit my LS block? If so does it flow more? Would it be better to run the GSR or LS water pump? 4. I'm still not sure of what fuel managment i'm going with. And i still am not 100% set on a tuiner yet. Anyone have any input on a great tuner in the new jersey area? 5. What else would you guys go with? New radaitor? grounds? 6. Valve train? What needs to be done to my head / block to hold 8k all day? I need the extra rev room for my turbo. Let me know.
