I'd like to increase my power while towing with my Gen II 5.0. I'm thinking about doing a rear turbo setup. I think this will be a very fun project and I have the equipment and technical skills necessary to do it, but I honestly don't know much about turbo chargers. What size turbo would I want to operate in the 2000 - 3000 RPM range? Will the turbo give any extra partial (1/2 to full) throttle power in the 1500 - 2500 RPM range while under a heavy load?
