Well if height isn't a problem, you might want to throw a liquid core IC under the blower. I heard that cartech used an oil cooler or something as their "intercooler" in the old turbo kits. Whatever it was, it was small. Water injection couldn't hurt (and can be done cheaply). Also you might want to look into 12A turbo rotors if you can find them cheap (8.5:1, same balance weights as standard 83-85). Roots blowers make alot of heat. While I think of it, you might be able to get the distributor advance diaphgrams for a 12A turbo - this will give you boost retard capability.
