Bought a GT22V... - 300SD81 - 11-10-2008
Finally getting into the turbo project I've had planned for like 2 years...

I think its the same one Forced is using? I'm going to go with full electronic control though. I already have the circuit boards for a new boost and EGT gauge planned out and will be starting on the turbo computer board as soon as it arrives.. Going to implement a CAN (controller area network) just like new cars use to connect everything together. I have a friend taking engineering here at UGA and he said they have a CNC, so I might be able to get parts made on the cheap as practice for students...
Re: Bought a GT22V... - ForcedInduction - 11-10-2008
Basically the same. That compressor wheel looks pretty chewed up and the turbine looks like the engine was burning coolant.
$75 isn't too bad but they do say it needs rebuilding.

Re: Bought a GT22V... - 300SD81 - 11-10-2008
I was afraid someone would say that... I thought it was just dirt on the compressor wheel in the pic, didn't look that closely since the auction was ending in a few hours and I had to go to class...
Re: Bought a GT22V... - ForcedInduction - 11-10-2008
Thats why I never consider buying a turbo unless they have a good picture of the compressor wheel.
It will still work and balancing should be part of the rebuild, but with worn leading edges it will lose some efficiency.
Re: Bought a GT22V... - 300SD81 - 11-10-2008
Would the reduced efficiency be below that of the stock turbo?
Re: Bought a GT22V... - ForcedInduction - 11-10-2008
I don't know.
Re: Bought a GT22V... - bgkast - 11-11-2008
It doesn't look too bad to me.
Re: Bought a GT22V... - Telecommbrkr - 11-11-2008
What is the make/model of the VNT found on the '03 & up Powerstrokes?
Re: Bought a GT22V... - ForcedInduction - 11-12-2008
Garrett GT3788V.
Re: Bought a GT22V... - 300SD81 - 11-13-2008
It came in today!!
Its a lot smaller than I expected, is everyones VNT smaller than the stock turbo?
How do I figure out the exact model number of the turbo, as in GT22xxV?
Re: Bought a GT22V... - 300SD81 - 11-13-2008
Found out from EPC that it came from an OM647, and got a part number for the gasket. Not having any luck finding the part numbers for the oil fittings though, hopefully its a standard thread and I can probably have the return flange made. Theres no way to clamp tubing to the outside of the compressor outlet, so I'm going to have to find a way to either friction fit it inside or I'm going to have to drill into the turbo to attach it. I emailed my friend's engineering professor about using the school's CNC machine, so hopefully he'll get back to me soon.

You need one of these: <!-- m --><a class="postlink" href="http://cgi.ebay.com/ebaymotors/Billet-Oil-Drain-Flange-GT-Series-Ball-Bearing-Turbos_W0QQitemZ360105089753">http://cgi.ebay.com/ebaymotors/Billet-O ... 0105089753</a><!-- m -->

The feed line is a standard metric banjo fitting, any good hydraulic shop will have one in stock.

Re: Bought a GT22V... - 300SD81 - 11-14-2008
Bit tougher than just grinding it down on this one, the actuator mount is attached to the outlet. I got the actuator off and opened it up today, not sure if I can reverse engineer the signals used by the existing controller, but I can definitely build m own controller... Taking it to my house this afternoon so I can clean it without worrying about getting fined for making a mess in the bathrooms here..do I need to worry about getting water into the insides of the turbo? I'll start on the actuator circuit when I get back from the Auburn game on sunday, love to have this running in time for the drive to the bowl game, but I doubt thats going to happen.. Not sure if I want to put the entire turbo computer on the turbo or just send position signals to it yet...
Re: Bought a GT22V... - ForcedInduction - 11-14-2008
The housing is normal aluminum. You could find the stock fitting to bolt-on or you could have one welded on.
