the real question is... who called who first? lol!
thats awesome man, i cant wait to read it!
Cyclemut with NSM and then the editor from off road mag is forwarding me to Diesel power (under same publisher). The diesel power mag article doesn't make sense for me because this isn't a high powered diesel, but I am game if they want to.

Yeah diesel power has everything from ford escorts to VW's my coworkers are crazy about the mags. I'm eagerly awaiting them to happen upon a xterra in the magazine and chat with me about it. Congrats man Nissan sport mag is a good mag.

at 19psi it has a lot more power, just need to turn up the fuel for it to multiply that. 10psi is about what stock was/is. If I want higher than 20psi I will need to run a bigger turbocharger as well as intercooler/aftercooler. I am using a mechanical controller (ball/spring)

mmm turbo talk, never thought id hear it on XN. music to my ears. just make sure the waste gate (blow off valve) is able to push out the right amount of air when letting off the gas, im sure your aware of the sound turbos can make when the right or wrong waste gate is on them. turbo cherp sounds cool but to much can wreak the bearing inside.
thats just my 2 cents!
thats just my 2 cents!
no blow off valve (intake pressure relief) here, that would only apply to turbocharged gasoline engines due to the throttle body (flutters when BOV isn't working due to surged charged air against a sudden closed throttle plate). For diesel, there is no throttle body and is just a straightshot to the valves. Fuel is what changes the rpms, no butterfly valve here. Theoretically you can shove as must boost as you can as long as you have enough fuel to back it up for compression combustion.
Another thing you guys may find neat is that the more fuel I put in, the hotter the combustion gets unless boost is upped accordingly (can equal complete meltdown). It is vice versa with air too. The more air you shove down its throat the cooler the combustion is (combustion is incomplete without enough fuel), but without either one you gain no power. Equalize both and just enjoy the ride.
Thanks for the heads up though Jim! I am just glad to not have to deal with turbo gas motors anymore... this is definitely more user friendly and simple.
EDIT: I think I will add ABLS to the X instead of lockers

i guess i learned something today. now that i think about it ive never heard a blow off valve on a diesel. i figured diesels would have about the same set up as a gas engine but since when the throttle is opened on a diesel your just controlling the amount of fuel, the air stays the same. i just learned about this at tech school. why didnt i correct myself earlier! oh well!

I wonder what that little motor is actually capable of if tuned to the max.
lol, well I ran into an long awaited issue... leaking fuel at the injection pump. I have been leaking fuel for awhile now but could never pinpoint where on the pump it was leaking until today at work. Saw a big stain under the truck and investigated the leak. Turns out the o-ring that seals the governor plate to the housing is leaking. Gotta find a gasket kit for it, and hopefully it shouldn't be to hard as it is a bosch VE pump like your 4BT guys run. It is almost identical. we will see.
btw, the thing was pretty fun to drive with the extra power. Almost feels doubled.

For those wondering this is an idea of fuel cost differences. 22mpg diesel and 14mpg gasoline
in diesel form $17.72 per 100miles at $3.90 gal of diesel
or at 15k miles a year at $2,658
in gas form $25.71 per 100miles at $3.60 gal of regular unleaded
or at 15k miles a year at $3,857

That's freaking awesome. If I had the time I would try a diesel swap, but I have no time.
Honestly for stuff like this it takes acts of gobble to be able to have the time and funds to do it. I was not working when I did it, but I had saved up over the year to do it and not work. Next time I will just import the whole truck, register it outside the country and drive it across the border and back so I can keep it here.
My wife and I had a talk about travel. In two years we are planning on doing the Pan American Highway with the Xterra. It will be refitted for the trip to meet the needs and use advice from others that have completed the trip successfully and unsuccessfully.
On this list for change:
1. lowering the truck or replacing the suspension altogether
2. possible repaint to sand, off white, or white
3. possible body change, if not then body modifications (for sleeping and storage reasons)
4. less aggressive tires that are better suited for on road travel
5. auxiliary fuel tank
6. undercarriage reseal
7. to be continued

Take 1 and 4 off your list and your golden. I dont imagine a real benefit with being lower if the lift was done properly. Also the road less traveled is more fun so keep the MTs.

Yeah can successfully drive with MTs on the highway. You can't successfully rock crawl/mud with highway tires. Same goes for the lift.

without reading your build...when you did the swap, I'm guessing you had to change the tranny as well. If so, how did you find which ones would fit? Computer/wiring harness as well.

Gonna make me work for this huh...FINE !!!! HAHAHAHAHA
the torsion bar system is much more dangerous to work with because it is under such high constant pressure (had adjusting bolts break too close to my face). Also I don't like the extremely limited downward travel of the wheels even with low pro bump stops after the lift. In order for me to level out the down/up travel I must lower it some.
M/Ts have been held deep in my heart since the beginning, but after reading up on others that have done the trip, most of the trip will be on road (crappy road). I have been using M/T's on the xterra and daily driving it like that (mostly highway) and had no real issues with them yet, but no matter what I will be buy a fresh set of M/T's or A/T's for the trip.
I will be doing some off road work, but at the same time I will be trying my best not to put myself in a bad situation in the middle of nowhere with almost none existent communications.

Yea I know... I was looking for specific stuff and was lazy. Didn't wanna read thru "stuff" when I could cheat and ask. I actually read most of the build anyway. Great job that re-inspired me into swapping out the 6cyl for a small block V8. Something I'd been researching off and on for a few yrs.
aww I see. I will let you cheat on this one! The tranny is the exact same one (model/gearing) with the exception of the bell housing, torque converter, and the 4x4 indication switch is in a different spot. The harness ends I assume were different also.

If your state doesn't require you to do an OBD inspection, this will not apply.
I'm guessing that the diesel no longer has some/many of the things that the computer monitored w/ the VG33. Does your state do an OBD inspection and if so, how did you get around the codes that are no longer supplied to the ECM that are required for the OBD test?
I saw you redoing the harness and wondered if you had to figure something special out.

We do OBD inspections, but as long as it comes up with no CEL and all sensors ready then it'll pass. He had it inspected about 7 pages ago

OK, thanks. So the Cat is the only signal/check that no longer exists. Lucky.
I do have the original ecu in the truck, but it is partially fried (accidental). I kept it so all my sensors can be read on my dash and use my OBD port. I do not have a CEL light on the dash, nor can you read code off of it. The OBD port will not even read (partially fried ECU remember) which if I had the vehicle registered in Travis county I would never pass inspection. I have it registered in Bell and I get inspected there. They only look for CEL lights, cats, and the normal inspection stuff. Also I have very persuasive knowledge while true, is a grey area.
If you called the guys in San Antonio that do the diesel conversions for toyotas, they will tell you and make you sign a waiver stating that their modifications are for offroad use only and not held liable for any legal issues for road use. I called these guys to see if they would do the conversion for me while I was overseas.... they quoted me IIRC almost $20k with me supplying the drivetrain. They also said it would not be easy and would require a lot of modification since it has never been done before... well I will say IMO it was easy and if any of you choose to do the same conversion on your own, just ask if you need help.

Man, I just read this entire thread. Holy balls. Incredible work, loved the videos, sound of it, and blowing smoke. I'd love to do the swap if only to see the look on the faces of the country boy Cummins lovers around here, especially my old boss lol.
