Oh and leave the SLP headers unwrapped. They're awesome all by themselves, however if it's the original flex, get it replaced with a double walled flex BEFORE you put them in the car. Learn from my mistake, they leak and it sucks to hear it driving down the road.
Oh and you don't need the bigger injectors, keep the stockers. Also, if you're keeping the VS cam, keep te stock retainers unless you want to buy titanium ones. Ls retainers are for xp cams. I think NIC cams can use stockers as well but I'm not sure, I already had ls retainers on my car so I kept them for my NIC build.
