isuzu 4BD1T swap?! (1 Viewer)

Saw this yesterday if you're looking to do a rebuild

Although the ad say 4BD1, it is a 4HE1 based on both the picture and the year. Also, the seller states "no fuel injection pump" amongst other missing items. I would only recommend buying this engine if you need spare parts for another - not a good candidate for a swap as too many missing pieces.

Is the 2000 model electronic? I saw that as well but just assumed I could not use it due to the fact of electronics. I guess if it is the same engine as the older models you could buy the parts and convert it, I have swapped a VW engine from fuel injection to a carb and it was really easy, could you do the same with this?

The 4HE1 engine is a completely different engine from the previous 4BD1/4BD2 engines. The injection seems to be primarily mechanical but there is a computer that is connected that modifies the injection parameters under certain conditions. You can make an analogy to the last generation of carburetors that appeared on gasoline engines before they switched entirely to electronically-controlled fuel injection.

On the 4HE1, a computer is connected to the mechanical in-line injection pump and modifies the operation. From what I read in the FSM, the computer advances the timing under certain conditions, reduces the fueling when the engine temp exceeds a set level, monitors various sensors in the engine and controls the "Check Engine" light, controls the exhaust brake, and generates the ODB codes.

I suspect that the engine would run without the computer, just not sure how well.

Any progress on the adapter and what direction are you going with it, a plate on the back of the motor or a plate on the back of the flywheel cover?
Thanks

Diesel conversion in a 99 Isuzu Trooper

I am interested in converting my 99 Isuzu Trooper with a 4BD1T engine. I use my Trooper as daily driver and want to get good gas mileage and power for towing (my trailer and '62 MGA) I appreciate if someone can help me answer the following questions.
1) What would be the gas consumption for a street daily driver with a 4BD1T engine? My trooper is about 5,000 pounds?
2) Does the engine provide good pick up for passing and go high speed up to 80 mph?
3) Are there anyone here done a 4BD1T engine conversion in a Trooper with the original Isuzu automatic transmission?
4) how simple to go to a 24V starter?

Any information is greatly appreciated. Harry

troopersafe, the 4BD1T moves my 5k pound FJ55 around pretty good and it has 37" tires. questions about enough power are hard to answer because i am happy but i dont know what you would be happy with, i think a v-6 would be faster but it doesnt net 25MPG like i get now, so i am happy. the engine is capable of alot more power if you want to mess with injection pump settings. you will be needing a custom adapter for your tranny, and its gonna be real tight under the hood. you might also want to check into the diesel isuzu made for the trooper, it might be a pretty good swap.

Feel free to post up these questions on the 4BTswaps forum that cdbridges linked up. I'm the moderator there. There the questions and answers might be able to help others.

My vehicle is within a few cm of width, height, length to yours but slightly heavier. I get up to 11km/l on the open road and around 8-9km/l around town. It's been a long time since I did a full tank around town though.

The engine is slow to wind up, don't expect 1/4 mile times under 22 seconds, but once up to speed it holds on hills very well. The stock power levels aren't dramatic, but turning screws on the pump fixes that.

You are going to struggle for height to fit a 4BD1 engine into a trooper, esp height wise. An Isuzu 4JG2 or 4JH1 will be almost a direct bolt in, smaller capacity (around 3 litres) but smaller, lighter, similar power and torque levels and more freely revving. In short car motors vs truck motors.

4BD1T's from japan are 24v, US versions are 12v.

Last call:
I have a dead A440F that I'd like to donate to the conversion cause if someone wants it. It's in Florida. I'll split shipping up to $70 if someone wants it.

If nobody speaks up it's going on the open market.

PM me please.

After four long months I finally got my truck back together. With the repaired aneroid on the fuel pump, it now gets full fuel for the first time since the engine has been installed.

The result is a little mental, on a slightly damp road it spins the back wheels. In second gear. On a vehicle which weighs 2.3t empty and is full time 4wd.
The power and torque figures of these engines match up quite closely with toyotas 1KZ-TE on paper. There's gotta be a big mistake there. The 1KZ-TE powered hilux can't spin the back wheels in 2wd.

euclid, have you mentioned that tranny to BRAM ?? maybe PM him ?

dougal i know what you mean,,,, my 55 is no rocket with the isuzu but i can easily chirp the 37" tires.

fj62 isuzu 4bd transmission

spent a month or so looking at the a440f bolt pattern, and the isuzu 4bd.

a shot of the a440 adapter from the toyota engine, sitting over the isuzu trans bellhousing. note these two components are what the plate would need to look like so that it could mount to the isuzu engine, and to the toyota auto trans.

This is roughly what it would look like.

I say roughly, cause i did not feel like the hole locations to be very accurate. I have roughly .050" that I am chasing around with measurements, or a compass arc. I feel like it needs to be in the .010" range, to avoid some gnarly vibrations.

I wanted to experiment with a wood trial part. although this would show if the adapter would bolt up, it would not tell you that the trans shaft, and the crankhshaft were centered. so I would have to mock up the cotton wheel spacer too.

I want to get my fj62 running, so I am committing to an isuzudieselswapper adapter, a 700r4 K case diesel transmission with a .71:1 overdrive, and a AA transfer case adapter to my landcruiser transfer case.

Its not going to be cheap, but it will be efficient, and reliable install. Honestly, it was not going to be cheap to rebuild the a440f to stand up to a diesel, and not cheap for the custom adapter.

I would like to continue working on this however. does anyone have a more accurate measurement system? a digital 3 axis milling machine, a visual comparator, or hell, even a granite block and a height gage? I have worked in shops like McDonnell Douglas, Leatherman Tool that had this accurate equipment.

Bram found one local to him: no shipping. Anyone else you know of looking for a big ass boat anchor?

I'm thinking now that this is the better setup for a lot of reasons, not the least of which being that it seems a lot easier.

i have been happy with mine, its well made and you have the option to run the engine forward a little for stock d shafts, or back a little to get the front shaft a little longer.


one word of advice, when drilling and tapping the flywheel for the spacer, be extra careful to measure twice and drill once. and when bolting the GM flywheel or flex plate to that spacer pay attention to not overtighten and strip those threads.

The engine is slow to wind up, don't expect 1/4 mile times under 22 seconds, but once up to speed it holds on hills very well. The stock power levels aren't dramatic, but turning screws on the pump fixes that.

After fixing the fuel pump aneroid, I have to retract this statement.
It hurls a 2.3t truck to 100km/h in just over 15 seconds. That's on a manual box with two gear changes (start in 2nd, 2-3,3-4).

I had my fuel screw wound out only 1/4 turn which produced EGT's of 800 deg C. I've just wound it back to stock, haven't found a hill suitable for a sustained load since.

Hello everyone I've been reading this thread for awhile now and finally have a question. I'm right in the middle of putting a 4bd1t and 4l60e into a 77 fj40. I didn't realize I had a flywheel for an NPR auto until I received my Isuzudieselswapper kit from david. So I ordered a new flywheel for the standard trans for my year engine.

Now when i place the spacer on the new flywheel, the edge of each hole that needs to be drilled hangs about 1/16 in over a stepped down area towards the center of the flywheel. The step drops down 1/8in and is 1/4 in wide. Then the flywheel steps down again to the center flat section where the flywheel bolt holes are. When i measured the other side of the flywheel i find that the spacer bolts would emerge in a rounded section of the flywheel not in a flat area.

I asked David and he thinks i have the wrong flywheel. I called two Isuzu NPR parts dealers and they say i have the right part number for 1988 to '97.

Does anyone have the right flywheel part number? Possible this is a industrial flywheel?

 

[Mr. Toad]

Wouldn't it be simplest to adapt the Cruiser T-Case to the rear of the tranny that Isuzu was kind enough to attach to the 4BDxT?

 

[RHINO]

no mr toad,,, if you read back the isuzu tranny is a bad thing to try and make usable, it uses a hard to modify linkage shifter.

zaks the stepdowns your talking about are on the engine side right? mine has stepdowns also and when you drill for the spacer holes they do come out on those, but there is plenty of meat there and hasnt proven a problem.

dougal i was wondering about that, mine isnt a rocket but it winds up just fine. out of curiosity what did you do to the aneroid?

After a lot more testing and driving I've decided the injection shop which last rebuilt the pump screwed up the settings.

I'm running 19psi boost and still have to back off to avoid hitting 800 deg C EGT's. Did I mention how much fun that is.
That is with the fuel screw where it was when the pump arrived back from a rebuild about 8 years ago.

My aneroid has the boost canister operating a pushrod by an adjustable lever. I've been adjusting that lever. The aneroid starts to move at 2psi boost and is fully open by 7psi. I need to back it off a little more as I am getting some smoke when idling away in second gear.

No affiliation, but maybe some New England Mudders might be interested in a factory rebuilt 4bd2.
