Thread: 2 series 3 PROBLEMS

The Isuzu/Landies were the Stage 1 or coil sprung models. The engine is a 3.9litre 4BD1 and will be bigger than the Isuzu in the Rodeo. They were originally fitted to the Range Rover 4 speed box (very strong) but are much longer than the SIII box.

The SIII box will not stand up to the 4BD1 and will have trouble on the smaller Rodeo engine as well. No doubt you could do it.

I have a couple of times seen Series Landrovers for sale on evilbay that have a 2.8l Isuzu turbo diesel. So it must be possible but I have no idea what is involved or even what gearbox they used etc.

With the green one - does it have freewheeling hubs? If it does and they are disengaged then it will not exhibit the windup problems on road. Easiest way to check is probably to jack just the front off the ground, engage 4wd and see if you can turn the front wheels. If it is 4wd then you won't be able to turn them, in 2wd you will.

I am pretty sure the Isuzu diesels in early Jackaroo's are 4JB1 or something along those lines, and later ones had a 3 or 3.1 litre TD with a different name. the Isuzu diesels in the series 3 stage 1's are a 3.9 litre 4BD1. I am fairly sure that they all come either turbo'ed or NA.

I am assuming you would need some kind of adaptor plate made up for any of the isuzu motors to mate to a series gbox as a minimum. I am pretty sure Isuzurover on here has investigated putting a smaller isuzu diesel into his 2a LWB.

The 2.8L is a 4JB1T - great little engine, direct inection and timing gears in Jackodeo spec. IMHO a much, much better option than a 300Tdi.

Then came the 4JG1T - 3.1L but indirect injection, so less efficient.

If it is newer than that then it will be a 3.0L 4J(J1T?) and you will have some electrics to worry about.

Adaptor kits for the first 2 are available ex-UK.

Any isusu diesel 2.5L or bigger will eat a series 4-speed for breakfast and spit out a pile of metallic gravel.

By all means buy it and fit it if cheap, but I would use the rodeo gearbox, and maybe divorced LT230 t-case (or the rodeo t-case). That will save you the cost of an adaptor from the UK.

I've recently stumbled across two Series 3 landrovers for sale, both of which have the Isuzu 4BD1 motor fitted to the series gearbox
Both vehicles also kept the original look at the front, ie the grille/radiator panel hadn't been moved.

I'd certainly be interested to know how they were done, were they one offs or was an adaptor kit available ??
