How is the long term comparison between maintenance cost of turboed 3B vrs 13BT?
Is the injector service more critical in a DI engine? I ask because a lot of 3B's don't have them done anywhere near 100k interval that is recommended and seem to do ok for the most part.
Is it more expensive/difficult to find shops to service a DI or IDI injector in NA?
Only other regular service item between them I can think of is the turboed 3B has the IP diaphragm and glow plugs that need occassional replacement.
Is the expected service life similar between equally well cared for turbo 3B vrs 13BT (installed into a short to mid WB 40 series)? What if the start point is comparing a 300k 3B getting some PM done then turbo, or a JDM 13BT with 100-150k on the import truck odo (obviously with a greater purchase price difference than peteinjp has been quoted)?

I've had a 13BT in my BJ42 wheeling rig for 10 years now. Love it. Have differing opinions in throttle sensitivity and mileage than Crushers though.
Had a 3B in my dd BJ73 for 5+ years. No turbo. Didn't really need it. Didn't offroad it either and it had stockish tires and not 35s like my 42.
Depends on what you want and what you want to do w it.
I recommend that you test drive some rigs w different engines and figure out what you like vs don't like. Everyone on here is going to have different experiences and advice so take it all w a grain of salt and make sure you compare apples to apples and not oranges when making your decision.

What did you end up buying peteinjp? About to pull the trigger on a BJ73 n/aspirated and was considering an aftermarket turbo.

I'm still thinking on the 3b. I want the tranny but he won't sell it separate. If the timing were different I'd just grab it, turbo the 2b and have the 3b as a spare. If he still has it when I've got either a little more time, money or space then I'll get it. Again the only reason I'd do the turbo is for the mountains/altitude. If I were not in a mountainous area I'd just stick with the N.A. engine for simplicities sake. Just my take. But its harder to get stuff done here in Japan then it is in Oz or the West. Almost no one turbos an engine themselves.
If you have not driven a b engine truck before prepare to be underwhelmed....

Pete take a look my 15bf into a 40
Pete, take a look at my build, I just placed the engine and you can see there are no clearance issues...I don't know what your plans are of either doing it yourself or getting someone to do it but it is really a simple swap, especially if you can get the bell housing from the donor truck..I could not find a 15bft or I would have done that. IMHO stay away from the 15bte as it is electronic and you could have computer problems the 15bf and the 15bft are not electronic and should be very available there as they power buses and trucks (coasters and Dyna's). Just click on the link in my sig line...hope you find what you want...Best, Lee PS, If you need more pictures pm me..

The fact that the 3b will handle viscous oils 10x better (because of pre cups(IDI)) and the 13bt being ID and rotary pump yuck its a no brainer in my head, 3B all the way.
I was tuned in early on in this thread, I had no idea it was still going. Did the OP ever get one or did I miss that reading through it just now. I am subscribed now.

Some later 3B's got rotary pumps, and the JDM 3Bs in the 7* series seem to be all rotary (someone will chime in if I am wrong).
"All" 13BT's that I have seen are the inline pump. Don't think they ever came with a rotary pump.

An injection pump can be overhauled a lot more easily and cheaply than a dropped pre-cup. Inline with IDI or rotary with DI. Easy choice and that's the DI. Just like the two I currently own.
Of course I have an inline Di engine too.
Oil too thick to inject? Try heating it.

I do, 30 plate heat exchanger. Just curious do you run PO, WTF, or any of the like on those DI's? Not being crude, actually wondering.
No, I have enough projects already without making my own fuel. The DI's are good enough on fuel that alternatives aren't worth the trouble. Plus we are taxed seperately to fuel. Even if I brewed my own the road tax still costs the same.
Same same, we are taxed as well. But the tax compares nothing to the 4$ a gallon we pay for fuel petrol or diesel. Have a hard time believing a DI gets that much better mileage. Road tax 24¢ per gallon (here) so that's 1/16 the cost. My 3b is only getting 19-20 mpgs NA and with my lead foot, and your gets? I pay 13$ for burning a drum of fuel. That's worth it. Can you burn on waste oils on a DI? sure the VW guys do it alot, it causes a lil more problems even pre heating but maybe not evough to worry about needing a idi.
Its all been laid out pros and con's and really it comes down to the individual owner think. But you know what stays the same? They are two of the best damn engines ever made!
And no one here will argue that!

I get 28mpg in a fulltime 4wd di which runs a max of 24psi boost (isuzu). Hit 30mpg a few times, but 28 is generally where it's at.
I don't burn waste oil because I don't think anyone should have to breathe the results. If the oil is too dirty for your engine bearings, why would you feed it through your injection pump?
We pay 4c per km driven. Gallons are imperial. 10km/l equivalent.
I also have a FPHE fuel heater on a 13B-T between the fuel feed pump and the filter. I burn a mix of ULSD, VO, BD, & jetB or petrol, with the proportions adjusted seasonally for temperature. Emissions tests show very clean exhaust with less than 10ppm HC and opacity at 1%. Cleanest older diesel they tested. 10km/l average.
Current fuel price about $5US/gal, 16% is taxes. I don't have a problem with the price, all our fuel is from domestic crude, so the money I spend on fuel keeps my neighbors employed, a roof over their heads and food on their tables.
I would never burn used engine oil in my vehicle, that s*** pollutes the air we breathe.

Dougal that is great mileage! Full time 4wd what vehical is that? Do you guys really pay per km and not per liter? Or is that just a break down.
Galt, the award winner for belonging to the most diesel forums out there, its good to know you actually have a LC. I know we discussed this before but I don't burn wmo just a fyi. I only burn wvo and sometimes mineral oil (PCP free) and very little diesel except for when I pump hho from people upgrading from their oil furnaces.
At any rate, in a attempt to stay on track. Lets get this guy a new engine any update on that or did miss it?

Yes we pay per km.
Petrol and LPG are the only fuels taxed at the pump, all other fuels (diesel included) pay road tax on a km driven basis. The rate depends mainly on the weight of your vehicle.
Up to 3 ton it is ~4C per km.
*edit*
Todays fill up was only 8km/l, this involved climbing an 1800m vertical hill for mountainbiking purposes and a lot of testing to see if I really did have 24psi max boost. Also I think it was last filled by the wife so may not have been completely full. The longest stretch of highway driving in this tank was about 30km. This is the worst fuel economy gets for me without towing something heavy.

Turboed 3B vs 13B-T (I dont know why I get involved in repetition)
turboed 3B has good grunt better power up to about 1200rpm vs 13B-T due to the higher compression of the 3B
turboed 3B has better compression braking vs 13B-T
I never see anything under 25mpg Imperial with my BJ 74
I made a simple cure for the sketchy throttle on the 13B-T
Both are great motors , I prefer factory turboed engines!
ps I have run straight Nuto 32 (STRAIGHT) like 60 liters to 1 liter of #2 diesel for a week with no ill effects.

What specifically is a 'sketchy throttle' and how did you cure it?
so 8km per liter is 22.5 mpg uk right? so 18.7 us
I have never gotten under 18mpg us and thats the worse I think I have heard a 3B running. Mine is natural aspirated fuel cranked up I will hold 55mph up our steepest hills. Running our mountains or long freeways pinning the B out is where I get 18mpg us or 22.6uk :edit 21.6 uk
You are comparing a 5.2 liter diesel running 24psi in a vehicle with a unknown weight? I asked what vehicle. To a 3B na with cranked fuel, posting the worst numbers I have heard of for mileage and you are saying yours is SO much better mileage you don't even need to think of burning free oil, and all because its a DI? so vehicle weight don't matter and the fact you run 24psi of boost. btw 24 mpg uk to 30 mpg uk is not a HUGE difference. I bet if I drove like you I would easily get 26 mpg uk.
Anyways lets play that way since nothing else plays a roll.
My wife's om617 gets 25-30 mpg us thats 30-36 mpg uk And guess what, Its a IDI
Just saying guys we have to have all the facts. Do IDI engines if they where the exact same engine have better mileage? sure are they better? thats up to the individual user. Do they get such better mileage you would never have to DREAM of running WVO? psh yeah right.
I think Dougal just likes to argue, I see it a lot on here. The rest of us seem to actually give pros and cons to each and what we like about them and actual good info to the users. I like seeing the torque curves of each ect because I don't own a 13bt. Thats stuff I want to learn.
Not comparing a 4hk1 to the two engines the OP asked about.
ok I'm done, knowing it won't stop here
