I also need to replace the glow plugs in mine but with summer upon us, I was going to put that off for a month or so. I also have been shopping for the pieces to add an intercooler to my OBS 7.3. I have a 6.0 intercooler but still need the early 99 intake spider and pipes. If I don't find the parts soon, I may bight the bullet and get the Banks Intercooler. Currently at the top of the Power Stroke To Do list is the dreaded up pipe replacement. I believe I'll be going with the Riff Raff up pipes and I figure while I'm in there I may as well upgrade the down pipe since I'm still running the restrictive stock down pipe. Doing the up pipes looks like it will require removal of the turbo so I'm also considering a compressor wheel upgrade while its apart. I'm currently justifying all sorts of parts and upgrades because in addition to my new car trailer, I have also recently inherited a 5th wheel to pull.

As you know I just went through the up-pipe turbo wheel stuff right before moab. It was a pain in the ribs and arms and shoulders and back. But well worth it. Im not sure but IIRC you already have a "wicked wheel" in your truck. In 99 they changed them out to the crappy one that has surge issues. Only way to go is either a 38r or the billet compressor wheel. You will cuss a lot when dealing with getting the y off the back of the turbo. Get a full set of new orings from dieselorings.

I don't have a wicked wheel but It was / is on my list of possible upgrades. Riff Raff has their own wheel that I was looking at, not sure how that compares to the others. You can buy the early 99 spider and intercooler tubes on ebay for about $600 but I was thinking about the options today and I was wondering if it is possible to use the later turbo, pedestal, intake spider , etc on the OBS trucks? I assume that there is something about that combo that does not work or it would be a more popular swap because it would allow you to use the larger "Super Duty" turbo. What am I missing? Also why is the riff raff wheel almost $200 while you can get the wicked wheel for about 1/3 of that price?

Ahh, but have you seen version 2.0?

I did a WW in mine right after I got it cause once I opened up the exhaust I had bad surge issues. The ww cured the surge but my mpg tanked as it doesnt flow as much air. I went with the riffraff billet wheel and it made a huge difference. My mpg's are back up and now it boosts harder/more with very little smoke if any on a hot tune once it spools.

ZOSO wrote:I would recommend doing a billet wheel if you have to pull the turbo for any reason. I see it as a well worth it upgrade.

Jeremy, I can see the conversation now:

Jeremy - Whatcha got under the hood?

UPS driver - deer in headlight look

Jeremy - It's OK, I wear brown too. Pop the hood! You might want to call your boss and say your truck is broke down.
