For the water pump Autozone can get a short 250 aluminum high flow pump. Don't run a high volume oil pump either as it will chew up the dist. and cam gear. And on the por15 paint if you go the chevy orange the color is not matched very well. Mine came out as looking creamey instead of bright orange, and definitly spray that stuff. The can says you can brush it but it doesn't work very well. As for the turbo stuff I haven't played with that yet.
