From a long term commercial service standpoint, the Isuzu 4BD1T or the 4BD2T which is related but uses a different IDI injection system than the 1T ot 4BT is a better engine. Those Isuzus are built like farm tractor or big rig 18 wheeler engines. If you ever actually manage to wear one out, you just replace the bearings, seals, and cylinder sleeves with basic hand tools. At worst get your crank journals reground and polished and the valves ground or replaced. The Cummins 6BT and 4BT, and the Navistar/International/Ford 6.9/7.3 aka DT444E engines are considered throwaway engines. Fuck one up, just get another, rebuilds are expensive because they require machine work at a specialist diesel shop the has the tools to do it. A 4BD1T or say an international DT466 or Detroit 60 series... Can go millions of miles, and when they need a rebuild if you're mechanically inclined and have good tools, you just do it yourself with an overhaul kit.
Interesting. I had a 1.5 VW and was able to get a cylinder sleeve for one that had been gouged by gasket bits. Rebuild was very cheap. I appreciate the perspective on these engines. And with a radiator like that, I'd love to put an Isuzu into something.
@@heinzletzte.6385 the the more common 4BD1T Isuzu engine is also direct injected. The less common 4BD2T is not. I don't know why they built a direct injected and indirect injected version of the same engine but they did. The blocks I believe are identical I think the only difference is the cylinder head and maybe the injection pump.
@@stevemcgee99 that may certainly be true, but a VW diesel is small and light enough any typical machine shop can probably do the work. A diesel truck engine in a pickup weighs like a minimum of 1100 lbs and is a big hulking thing, the diesel in something like a big rig is literally a ton or more. You need to go to a specialist to work on something like that, which is why they have "in frame" overhaul kits where the sleeves can be replaced without having to take the engine out of the truck.
I’m guessing that that japanese injection pump is what is branded a “diesel kiki”, it was a subsidiary of bosch and they since got renamed or should I say fully integrated into Bosch since 1991.
Where i’m from, the Philippines, most 1st and 2nd Gen Ford Expedition and some F150 owners had those gas guzzling V8’s swapped out for Isuzu truck engines
Nick Tullos lol, took me a year to reply to you. Well, I ain’t sure what kind of trans really, I’m guessing they mostly keep the manual trans that comes with most isuzu truck engines we have here. I don’t see much automatic Isuzu Elf trucks (N-series) where I’m from.
Ford superdutys from 98 to 2011 came with a cummins 4bt then switched to the new electronic 2.8 and the 3.8 was an option. Would be nice to have 1 with the 4bt then another 2ith a 6bt since everything would work on the truck, unfortunately we got stuck with the 7.3, problematic 6.0, 6.4 and 6.7. Imagine a superdudy factory with a zf6 & 6bt. Why not they put the 6bt into f700's. When I put my 6bt from a 95 f700 into my 85 f350 Ibused the cab from the 700 since it was the same as the 80's bull nosevtrucks andvall the gages worked and ac. Bought the 700 cheap at auction with 32,000 miles on it.
we have a Deep Forest Passenger 4X4 that has a NA 4BD1 Engine Diesel prices went sky high and got to the point where the pumps ran out of them so we had to resort to using a mixture of Filtered Used Cooking Oil, Used Motor Oil and some Gasoline and sometimes just filtered Dirty Leftover Marine Diesel from the docks I mean it runs fine no seizing of the engine, no damage to the fuel injector pump 🤷♂ tough engine this is
No it's not, he clearly states it is a vacuum pump for the brakes... And I've seen plenty of them in person to confirm that. They also cost an an arm and a leg...
Looks like you have a ton of videos on the 4bt swap. I'll have to watch those. I've been trying to document every step on my blog/website. Mostly so I have a record of what I did.
I just want to ad that there is also a 6cyl in the FRR. Much like the 6bt, 200 horses and ??? Torque monsters to do work. The one I have seems legit. It pushes a 26ft box loaded with house furniture like a boss.....!
I like that izuzu diesel id use as a daily driver id use it as a modified pickup convert it to 4x4 and a crew can and make sure id piss off then greta thunberg greenie climate change nazis
@@williegohard1368 the main problem with the 4BDs is there isn't much aftermarket support. The factory transmission only goes to 1:1 so you don't have overdrive. Once you get it installed please send me a link.
which one is easiest" to get adapters for to swap into ie" a 03 gmc 1600 w/ nv4500? any help you could give m, or and sites, laces too find adapters too swap a 4bdt into a gmt-
I've got a 4bdlt I'm getting ready to put into a military M715. I can tell you with absolute certainty that there are vastly more adaptor options for the Cummins. Adaptors for the Isuzu are almost non existent. There were some people making adaptors in the past but doing my research I haven't found anybody currently making adaptors. There are some 4bd1t engines floating around with SAE #3 flywheel housings, early engines in domestic trucks and most industrial engines had them. If you have a SAE flywheel housing you can find a adaptor to fit pretty much any domestic engine. The vast majority of these engines have a "Japanese" pattern, which pretty much doesn't fit anything except the Japanese transmission that is bolted to it. That being said, some careful measuring and a trip to a machine should should net you a adaptor that will work. I currently have my parts at a machine shop to get an adaptor made to bolt up to a Spicer 3053a transmission. Was quoted a price of $500, which is actually cheaper than adaptors you can buy for say a Cummins.
Isuzu Engines are just better 🤷 even the 100hp Mechanically Fuel Injected NA version can give 17-23MPG with 2 Tons of stuff in the bed. with a Turbo it is even more efficient it doesn't go below 20MPG's
if they are using the same turbo then the power level is pretty close. Its really about which engine you can purchase for a good price since they both are really good engines. I like the 4bt better since they share parts with the pretty common 6bt in the older dodge trucks.
how big of a load do you pull? if your pulling most of the time then I would just toss a mech. 6bt into the truck. Not much of a difference between the two.
They both vibrate on start up and shutdown, but I drive a pretty big truck so I dont notice it. I believe the 4DB1T vibrates less from what others have said.
google "isuzu npr alternator vacuum pump" and take a look at the results. I think its a vac pump on there somewhere, but I'm new to these engines and I didnt trace the hose to the vacuum canister
looks like there is 3 hoses on my alternator. maybe they are oil inlet, oil return and a vacuum? I'm not an expert at all, but that will change over the next few months. I just picked up a vehicle this weekend for the 4bd1t swap.
