What is your current MPG now that you apparently have most of the bugs worked out?

You know I haven't gotten a full tank through it yet without a trailer or flogging it while adjusting fueling. Latest half tank was about 19 but that's with a heavy right foot. I think it settle in around there.
That's awesome. Im seeing 18 on my normal daily routine. Before I was getting 11-12.
18 mpg average is soooo much better than 12 or even 14. Slobbering. What are you getting while towing? Any idea how much your trailer weighs with all the camping apparatus and gear?

With towing the trailer I got a corrected 19 mpgs. The trailer and gear is pretty light...right around 1100 lbs loaded. I'm pleased with that. Looks like the 19.1 I was getting actually gets me right at 20 mpgs when I adjust for tire size...which was my goal. I'm happy.
Nice update.
Between you and Jeremy I think I know which way I'm going with my swap, I had planned on an LS but I've had a soft spot in my heart for a diesel.

I'm pretty pleased with it, but it all depends on what you want. I've heard guys claim 18 mpgs with an LS and a ton more power. The bugger for this one is working out the adapter. It sounds like threeeyedbandit is getting close to having one ready though, which would make this a lot easier.
20 mpg towing is pretty hot, even if towing a little trailer. My trailer is a little heavier: 2200lb with gear but no water. I wonder how your rig compares to mine with 1FZ in the hills. I'd love to see the torque curve measured the wheels of one of these conversions compared to stock. I bet that Isuzu 4 banger pulls and drinks about half the fuel while doing it.

Been a while since I did an update. Been happily driving the truck without problems until this week 
I rebuilt my turbo a month or so ago. First turbo rebuild but it seemed pretty straightforward. The other night I was driving the truck when something catastrophically failed in the turbo. I used an mhi rebuild kit but it looks to me like something seized around where the oil seal snaps on the shaft of the turbine wheel. There was a pop (sounded like an intercooler boot popping off) and I lost all boost and EGT's climbed quickly. I pulled over and there was nothing visibly wrong and it still ran so I limped the 2 miles home low on power. By the time I got home there was oil leaking out of most the turbo seams. Yowza.
I think the turbine shaft is shot. As is the compressor wheel. Both contacted their respective housings. Not sure about the compressor housing. Looks like I'm in for a new turbo.
I'm thinking of switching to the 6cm housing based on wheelingnoob and Dougals experience. I called a local volvo tuner to ask about what years to look for and he seemed to think it wouldn't make much difference. He recommends a Porsche panamera -18t turbine wheel with billet compressor wheel as that lightens the rotating mass by 115g. He's sending me some info, but it sounds like a 600 dollar plus upgrade. At the moment I'd just like to get it back on the road....
Here are the carnage pics....
Any experts want to weigh in on what parts are shot here? Do you think the compressor housing is serviceable? I have another turbine shaft and a 16t wheel that I could put it back together with. The turbine side journal bearing is toast though...

Not serviceable IMHO. You'd have to have the turbine and compressor housings machined to be serviceable, but at that point, you're talking about upgrading the turbine and compressor turbine sizes to compensate.
Start shopping for a new turbo.

I'd polish up the compressor housing and see how it looks. A polish will remove the surface discolouration and let you see what deep gouges remain. It looks like the compressor slid forward into the housing. Did the thrust bearing collapse?
The shaft doesn't look that bad in your photos (I've seen worse). When it's clean are there any ridges that catch a fingernail? The seal ring seat does look pretty chewed up.
For the porsche upgrade to save 115g it is likely a ceramic turbine. These are lighter but a lot less tolerant of abuse. I'd stick to steel. The 19T wheel is more surge resistant than the 18T.
Changes in turbine housing size are significant.

Thanks for the input guys! I'm gonna try and get to a junk yard and see if I can find a 6cm housing. If anyone knows what years and models the 6cm came on Id be super appreciative.
I don't know how many dead Volvos you have lying around, but one of these might be good for a core.
They need a decent performance thrust bearing kit in them and balancing to reduce failures at higher boost pressures, they will spin in excess of 170,000rpm.
Volvos run the following td04HL's
TD04HL-13G, Volvo 850 LPT, X70 LPT
TD04HL-15G, Volvo 850 T5, 850R
TD04HL-16T, X70 T5 98-00
TD04HL-18T, 99 V70R
TD04HL-19T, 00 V70R
I don't know how accurate that list is and most will be 7cm or 8.5cm housings, you will have to double check yourself, may get you a better core.
Saab TD04HL-15T 6cm2 - Found ONLY off 1994-1998 Saab 5spd Aeros (2.3 Versions) all t25 to manifold. Just need an adapter plate.
I believe Iveco /Fiat turbo daily 04 & 06 3.0l F1c euro3 & 4 diesel run a td04hl - 13t - 6 .
Porche will probably be a 3 stud flange to the manifold.
I used a kinagawa universal td04hl 19t 6 t25 11 blade turbine with adjustable actuator and hose fitting kit for $800 au delivered with a t3 to t25 adapter $32. If anything happens I'll just get a new chra .

Thanks! I have the 99 v70r turbo on it at the moment, but am looking for the 6cm, straight flange volvo housing to get boost a bit earlier. Looks like the only option for that is aftermarket or Europe...:-(.

I think it has the offset housing though. I'll keep an eye out.

Thanks! I'm thinking Saabs might use the TD04L...instead of the HL...which I think has a different turbine wheel size. Do you know if this is true? I'm functioning off of pieced together info from a couple sites so I could be very wrong

I've found mixed info, mostly stating that the L is a smaller wheel. And somewhere that the L had a different diameter shaft. Do you know what diameter shaft yours has? I could compare it to my L sitting in the shop if you want to compare. I'll also get some measurements from the turbine wheel.

Nuts...I just assembled it so I can't measure it at the moment. I'll be taking it a part here in a few weeks and could check then. I'm gonna settle on the Saab being a smaller turbine and just go the Volvo/Kunigawa 6cm housing route if it turns out to work well for wheelingnoob...
