ok here goes, my dad has a 2000 crew cab dually 4x4 auto. it has a 4" downpipe, 4" exhaust with muffler and a 5" tip, and an air filter. those are the only mods so far. We plan on going with a gryphon tuner bc he really likes the edge cts but ive read bad things about the tunes with the edge so the gryphon is a better choice. He doesnt drive it much but when he does its long highway trips, or around town, we tow a little bit and when we do its pretty heavy (3 horse trailer, and a 32' enclosed car trailer). ok heres my problem, he was getting a TON of oil smoke out the exhaust so I figured it was a bad turbo seal (i have a cummins and they are notorious for that) so we ordered up a WW and an overhaul kit. We took the turbo off last night to rebuild it. There was almost a 1/2" of shaft endplay! it took out the compressor wheel no big deal we have the WW to put in. It also wore some off the turbine wheel. We have a complete turbo off from a 2001 e350 bus. its got the 1.15 non wastegated housing. Ive been reading for like an hour and ive basically come up with these two options. find a new turbine wheel and shaft, and rebuild the stock turbo with WW. Or swap on the "van turbo." my questions are will the turbine wheel/shaft from the van turbo fit the truck turbo? Is the van turbo a better choice? what all do I need to swap on the van turbo? is the van turbo gonna make a lag master out of it? we have no plans to do any injectors just a programmer. were not trying to make a racecar out of it, just a good reliable rig to drive and tow with, honestly it had enough power the way it was. We were going to take it on a road trip this weekend but that was before we found the worn turbine wheel. Id like to get it fixed so we could still take it but its such a pita to get the turbo out I only wanna do it once. So if we end up waiting on a stock turbine wheel should I get a non EBVP pedestal and get rid of that oil leak? sorry for the long post but I know nothing about powerstrokes, thanks a bunch!
