Hi OilBurners, I have a 94' F350 dually crewcab I use to pull a heavy boat in California hill country. It runs like it should, but is really under powered with the factory 7.3 IDI turbo and E4OD, and 4:10 gears. From what I understand, with a better turbo and down-pipe it should run as strong as an early Powerstroke. So the question is; What turbo should I buy? I've been trying to get hold of R&D research for days with no luck. If they are still in business I would worry that support isn't available. Banks is expensive. However, I would be willing to try either with good recommendations. What ells is available? Thanks everyone!
