Thread: Defender 4bd1t

There seems to be a problem with any Land Rover gearbox long term behind a 4BD1. Predicting the inevitable demise of my box anytime over the next few years I have been researching alternatives. A suggestion I was told was a diesel 80 series Cruiser gearbox. It may require a few mods of the transfer and propshafts to replace my standard LT95.

what about an isuzu NPR box and a remote transfer? anyone done that you know of?

the TDI can be tweaked to equal the 4bd1t and then you can tweak the suzi

Both engines can handle WVO and bio. (with some minor mods to accomodate the eventual failure of seals, lines and filters)

you can rebuild the TDI with out needing to be a rocket surgeon ditto the 4bd1t.

the LT95 is the trans of choice for the Suzi especially if your going to take full advantage of what the 130 is capable of with the 4bd1t (think of it as a perentie 6x6 sans the extra axle and you'll get what I mean)

You'll get one with a TDI so that'll be cheap and the amount of effort and money you'll expend obtaining installing and getting approval for modding it all to take the suzi will pretty much buy you a replacement of or rebuild of the TDI and the gearbox thats behind it.

the other side of that is the TDI has an anticipated life where as most people regard the suzi as the engine that will be laying in the corroded out hulk of the landrover surrounded by the corpses of the cockroaches that survived the nuclear holocast waiting for someone to give it some diesel and a fresh battery so it can get on with shaking things to pieces again.

hope that helps.

Maybe you should just buy this one -

I think Bush65 has a setup similar to that, and a 6 speed box would be very nice

However

80 series cruisers are plentiful in wreckers and may be a cheaper option if it works.
