odd turbo setup, what do you think?
This one here: eBay Motors: Ford 6.9 7.3 Diesel Turbo Kit Rebuilt Nice Navistar IDI (item 250304164519 end time Oct-14-08 14:29:29 PDT) It seems like an easier install than your typical Banks or ATS or Hypermax setup, and I like the fact the turbo has been rebuilt and the system is essentially ready to bolt on and go. Considering that, price seems not too bad either. What do y'all think?

That's what I was thinking too. But someone on a different board said this setup builds up lotsa backpressure in the manifold before the turbo, not too sure how that happens, or if tis a concern... Any ideas on that?

Okay, something that was brought to my attention - having such a long up-pipe from the passenger-side bank may decrease the useful heat that reaches the turbo from there. However, that will be from just one bank of the engine - in other words instead of having two medium-length up-pipes like the stock setup does this one had one long up-pipe, which may actually be shorter than the two stockers combined, so less heat loss overall? And there's the fact the turbo is right on top of the manifold, so while it does get some heat loss from the passenger-side head, the driver-side one gives it a full blast of all it's got as far as EGTs... Any thoughts on that?

I don't see the lots of backpressure in the one manifold thing being an issue, nearly every FWD V6 out there has a smililar setup. Heck, IIRC, that's how gm did the 3.8 and 4.3 turbos, and they work just fine.
As for the legnth of the uppipe, that has nothing on what's on an old style non gated Banks system... The Y on the one on mine was nearly at the bottom of the oil pan on the drivers side, and the turbo was bolted to the pass side head... Probably a good 6' total run from the pass side manifold, probably 5 from the drivers....

the "water cooled turbo" part is what scares me.
water cooling a sealed bearing, instead of oil to the bearings??

id say its a sham, look and the exhaust down pipe... it goes away from the manifold and it couldent be routed unless the manifold goes it would have to be mounted right behind the motor for it to work.
and the water cooled thing it wouldent work.... it would get boiled off and have any one ever heard of the brand? i havent

Theres no big deal to water cooling. There is the oil feed and drain back like any other turbo, but there is also separate plumbing in the center section to use coolant to cool the bearings of the turbo. I have some T3 cores that I bought cheap a while ago and they have this feature. This setup is very similar to what was used on the chevy 6.2/6.5 diesels and they certainly do build boost.

The setup is the old RotoMaster used more in the industrial market. Certainly not a sham.
Rotomaster was gobbled up years ago by Garrett/Air Research and dismantled. They are in business under Roto International now.
I don't see any problem using coolant along with oil. Seems like it would help warm up a bit quicker and blow warm air in the cab quicker in cold weather. Water leak would be no more or less a problem than any other water cooled component.
