I'm planning to boost my Si(nitrous or s/c). My question is this, if I install dual valve springs, titanium retainers, and stainless steel valves, will I safely be able to set my redline to 8g? If so, how do I go about resetting my redline? And finally, where can I find valves, springs, retainers, ect. for my car. Thanks for your help

Answer is yes, 7700rpm is safely done with just stock parts using the NA Hondata ECU upgrade. Using those upgraded parts you listed 8000rpm is no biggy.
ECU tweaks can be done at www.hondata.com
They don't have anything on Forced Induction setups YET.
You could also strengthen up the bottom end with rods and pistons, try www.cybernationmotorsports.com they should have all the parts you are looking for.
