water pump should be fine, idler pulley... i wouldn't worry but if you need piece of mind then go ahead. if it is an 8 don't worry about the cam gears. what size are the injectors?

 

I have fic 880's that I want to use for the break in period and then I'm going to get 2150's in the spring when I get the big turbo setup and full tune. I would like to do the break-in on e85 because that's going to be the primary fuel for the car, but I still have my doubts that 880's will be big enough, even on stock turbo.
