Hi Georg,
There was a link posted a while back to a site that discussed swaps using this engine. i'll see if I can find it. If I recall correctly the engine redlines at 3k, but has a very driveable power curve. The trouble has always been the elusive SAE adaptor and I believe the truck must be lifted to clear the oil pan like a cummins motor. __________________ 1984 JDM Hj60, RHD, ARB & limited slip, high roof, Alcans, 35's, 4.56's and a whole lotta fun |

This swap keeps coming up time and time again! Please, someone do it and document it so that I have some one's example to follow.
I have a 4BD1T and a 4BD2T that I am considering swapping into my FJ62 after I finish my SOA (might be a while at my speed). The 4BD1T's came in Isuzu NPR trucks from '86 to '91. They were turboed but not intercooled and were rated at 121 hp @ 3000 rpm and 232 ft-lb @ 1800 rpm. They use an in-line mechanically-controlled injection pump and are direct-injected. The 4BD2T is basically the same block as the 4BD1T but the head configuration is changed to indirect injection. The 4BD2T's came in Isuzu NPR trucks (also re-badged as Chevy and GMC) from '92 to '97. They were rated @ 135 hp @ 2800 rpm and 255 ft-lbs @ 1900 rpm. The 4BD2Ts were intercooled in addition to turboed and I suspect the intercooler was primarily responsible for the increase in hp and torque. The latter (4HE1TC) engines increased displacement from 3.9 to 4.8 liters, went to an overhead cam configuration and went to electronic controls on the injection. They also swapped the intake and exhaust sides of the engine so they are opposite to that of a LC. These engines were rated at 142 hp for manual transmission models and 175 hp for the automatics. My understanding is that the bell housings are not interchangeable between the 4BD and the 4HE series engines. I've been following the various threads discussing installing these engines in LCs but have not come across anyone who has actually done one, although some claim that it had been done. No one seems to dispute that this might be a great swap. Most people seem to want to mate the Isuzu engine to a LC transmission or to another transmission for which there are adapters to LC TC (ie NV4500). I would like to consider using the stock Isuzu manual 5-speed and mating it to the LC TC, possibly using the Toybox as an adapter. Not at all sure if this is feasible. The MSA5D 5-speed fully synchro manual transmission that comes with a 4BD1T has a 5.67 1st gear and 5th gear is 1:1 (no OD). Everyone that I know that has experience with these transmissions say they are bullet-proof. The down side of using the Isuzu transmission is 1) mating the output to a LC TC, 2) setting up a means of shifting as these are not top-shifted but rather use a series of external rods and levers to connect the transmission to the shift lever. I'd love to see someone undertake this swap project and post their experiences here. |

i'd like to see this swap too. Astar, the diesel isuzu trucks that you can get this motor from, where do you find them. i dont think ive seen any in canada. although i have seen lots of bighorn diesels in New Zealand(trooper variant). Which engine adapter are you refering too? you say nv4500. what will work to use h55 transmission do you think? also they sound like a good power. i would be scared to throw in a heavy torque monster like cummins 12 valve. also since you have a couple of these could you post a couple pics for the rest of us.
i think one day we'll convince someone to take on this project. __________________ 83BJ60,Merkur turbo+intercooled,SOA,aussie locker Custom bumpers,,4.88's, longs and poly rears.RDB's +4runner calipers, parabolics in front, 39.5 IROK's on DC-1's 92FJ80 stock with the damage multiplied. 350 soon to come. |

sorry what does the abreviation NPR mean?
if the engine+transmission+t-case fit and are on the proper side then the obstacles are getting the wierd side mounted shifter through the floor and fabbing up new mounts and crossmembers? __________________ 83BJ60,Merkur turbo+intercooled,SOA,aussie locker Custom bumpers,,4.88's, longs and poly rears.RDB's +4runner calipers, parabolics in front, 39.5 IROK's on DC-1's 92FJ80 stock with the damage multiplied. 350 soon to come. |

to get back to one of the earlier posts; the engine i'm looking at has a decal on the valve cover. it states build date 12/88 and Hp rating of 126. definetly looks a little smaller than the 4BT.

As far as the intercooling, the turbo setup on the 1T and the 2T appear to be identical except that on the 2T the output of the turbo is routed forward and through the intercooler which is mounted in front of the radiator then back to the intake whereas on the 1T the turbo output is routed via a 2" pipe directly to the intake. |

Regarding the NV4500 - someone makes an adapter to connect this transmission to the LC TC. I don't remeber who. Regarding pictures - I plan to pull the 4BD1T out of the NPR in the near future. Once I do, I'll take some pictures. I'm not sure that i know how to post them but I'll try. I'll also get some exact measurements and weights |

If you are planning to use the Isuzu auto, how were you planning to connect it to the LC drivetrain?

Have just bought myself an 88 Izuzu Npr Engine, Head has been re-done. All trinkets are included. Starter, Alternator etc. etc.
Am going to be installing it in a 76Fj40 as soon as I have stripped the bottom end of the block down. I Think I am going to start a new thread in the 40 section, Because really I am building what in my opinion is an expedition truck. But the first part will be the engine transplant and running gear. I will post here when I strt the thread. And keep looking back here to watch for any tips |

De Toy expedition Build!
Ok…
Did I say got the engine, Well I am still working the details out on the transmission and Adaptor. The engine seemed a stunning deal (Good Old Craig’s List) It’s an Isuzu four pot out of a cab over truck. An 1988 model. The Vin is JALB4B1H7J7002512. I am trying to find a little more on the engine spec from Isuzu. The Guy who owned the truck went bust I think. Any way- long –story-short the head has been completely rebuilt. The Bottom end still needs some work. But the whole unit came complete with re-manufactured head, new rings and Big end bearings, gaskets and such yet to be installed. And all ancillaries from the radiator back, turbo starter motor and the Like. For $400. It seemed like a good deal. So I will be bringing it into my living room tomorrow, after explaining to the wife that it’s the new style Ikea Coffee table! And just needs putting together! And doing a quick re-build. If anyone is interested I will post picture of the engine tear down and rebuild. But I guess as its not Toyota It may not be well received. I am thinking about ten days to get the re-build done (That four letter word work keeps getting in the way). I really don’t know which way I am going with the Transmission yet. I want five speed, and have a good friend in the UK who knows more about gearboxes than I know about beer! And that’s quite a lot. So am taking his advice. It may be a Jeremy Fearn conversion. Again that’s a UK company but I can’t seem to locate what I need here. The Fabrication will be done at Custom 4x4 here In Atlanta. I am pulling a very good 2f out. But need to go diesel as we are building this FJ40 for a round the world trip. And there are river crossings aplenty along the road of bones in Russia. And not many gas stations!!!! So the implant may be a bit unusual along the fuel feed side. As we are Fabricating a Tank that Basically fits the truck bed up to the inner tub wheel arches. Carrying a whole lot of diesel. And water on the other side. All the baffles ECT needed to stop us swooshing about. The air intake and all breathers on the engine axles etc… are going to be fed through a custom made external cage. And will be central on the forward roof tent protection bar. So way high up. As are all the electrics and eberspacker diesel night heater. But I guess you guys are interested in seeing how I get the motor in, and what transmission we will mate it to. Well so am I. Sh$% Saving a whole heap on a cheap motor may have been false economy!!! Any How. Threads Like pictures. So here are a couple of the truck it is going in. The fist one is of the way I found the truck In September. Followed by one of were she is now. A little disclaimer here. I am not a mechanic, Far from it! So if I am doing things the wrong way please please shout up. I am a traveler I suppose, and know I need to know every-inch of my truck so I can mend it along the way. I have traveled extensively in a Land Rover. And a 50-year-old Willy’s. And know them well, but have a whole lot to learn about FJ’S. I already know they are a dam pretty truck thou. Cheers. |

What's wrong with the old tire/wheel combo, besides wear?
