Isuzu diesel into rangie

[kylepres]

Hi everyone,

new here so hello! I was wondering if anyone had put an Isuzu 4bd1t/4bd2t diesel engine from a Isuzu npr/GMC W4 into a range rover. A lot of guys in australia have done it but I was wondering if it would be possible with bits sourced from within the USA. I'm not too bothered if it ends up being a manual or auto, but obviously would like the 4x4 to work! Could I use the transmission from the Isuzu or Range rover or would I have to swap it for something different because of either size restrictions or lack of strength. thanks for all your help!!

I used a 4JB1-T sourced from a used parts dealer out of Japan and a mating kit from GB.

I had heard rumors of someone from New England putting a 3.9L Isuzu diesel (probably a 4bd1t/2t) into a RR but he did a lot of custom fabrication to get it in there. The 4bd1t/2ts don't generate more HP or torque than a 4.6 RR V8, but I have heard that the 2.8 International PowerStrokes required modifications to the drivetrain to work in a RRC.

I've already put over 20k on my 2.8 and love it... driven it from ME to CO a few times now and no major issues with the engine...

Go Here and look for Dougal he has a 4BD1T and MSA-5P box in a range rover and he can tell you a lot about those swaps, they are popular in Oz.:

The torque and HP seem similar between the RRC's Gas engine and the 4bd1t but the RRC's ZFhp22 won't like the bigger Isuzu Diesels...

Thanks for the info! I'd saw that kit advertised and it looked like a good one, considering that the 4JB is a lot lighter than a 4db but the engines seem to be very hard to get hold of! Are you running the engine as stock or have you tuned it? What sort of mpg are you getting?

thanks again

Pretty much stock. I usually averaged around 24 mpg but that's dropped recently, not sure if i need tuning/timing adjustments or possibly my injectors replaced but i'm still running at 20 mpg (and it is winter of course so it does a lot of idling to warm up). Depending on where and how I drive sometimes I can get as high as 29/30...

You could get a drop like that just from winter blend diesel.

[dieselrangerover]

true, but i noticed in the fall back east and am not quite sure when they started blending diesel, also, i don't remember it dropping quite as bad the year before. I have reason to suspect the injectors too because sometimes when its warm it starts had with a lot of blue/black diesel type of smoke.

it can never hurt to pull the injectors and have them tested anyway, besides, it gives me an excuse to drive my brother's IIa for a week or two

Before deciding on the 4JB1-T 2.8 liter turbo diesel, looked into the delivery truck engines and even helped a friend in NC remove one. Those engines are huge diesel clunkers that weigh about 800 lbs.

The 2.8 TD is so smooth, it's hard to tell it's a diesel. The timing belt is replaced in less than an hour. We installed a Ford Tarus SHO alternator that puts out 200 amps and got rid of the little alternator with vac pump that puts out only about 80 amps or less.

I drive a manual 300 TDI 110 daily and the Isuzu 2.8 auto seems to have a lot more pickup and more top end in the RR. The Isuzu 2.8 TD in the 110 was much much faster, but didn't quite match the 300 TDI at highway speeds being about 5 to 10 mph slower at max possible speed with the petal all the way down on both vehicles.

Looks good. I never hooked up the kickdown cable, just shift when i feel the need and it's pretty smooth. maybe at some point I'll have all those things done. Out of curiousity, what radiator did you use or is it a custom jobby with an intercooler?

[rdavisinva]

Knowing the effect or the kickdown and the workings of the ZF, if the shift points are not correct in certain gears, you can grossly overheat the ATF internally and suffer a failure. I tried the conversion with the stock governor and didn't like it. The governor suited for the diesel worked much better as well as a correct spec torque converter. No offence, but I think you don't know what you are missing by not having this set up properly. With the shifting correct our RR Classic and 110 are both so smooth and quiet, the result is outstanding. Do you ever floor it and suffer an annoying high rev down shift?

We used a 200 TDI Radiator and 300 TDI intercooler modified to fit the Isuzu 2.8 TD. We still need to get some fancy looking intercooler plumbing instead of the current rig up... aluminum pipe with silicone connectors. For now all is functional.
