I know that my 83 NA 6.2 conversion won't get out of it's own way. Yet it gets 25mpg. Everyone I heard, that has put a turbo on a 6.2 confess they can't help pressing harder on the acc. pedal. I know that kills mileage. I own 3 VW TDIs they all have intercoolers and turbos why? Did VW have alot of parts laying around? I've been told you can't run a diesel engine lean. So why not cram lots of cool air into the engine and a little fuel? I knew a guy who had a banks on a 85 c1500 pickup pulled a motorcycle trailer across the country, got 28mpg. I may not like the mpg of my van with a turbo but I'm going to try it. I had driving it in traffic!
