Thread: Isuzu into D1/RRC

Can it be mated to a late R380? Sure if you throw enough money at it but it will eat the input of the r380 for breakfast.
Is the engine in the 4t trucks the same? (also see Q1)some isuzu 4t trucks yes but witn minor modifications to the guts and the pump in some cases
Is it a heavy engine compared to the V8 for instance? yes the lifting block for a V8 is 300kg minimum the isuzu 500kg minimum so yeah its a lump of donk.
What is it like for noise compared to say a 200tdi? after your eardrums rupture you will no longer notice the difference
Is the standard D1 gearing suitable? yep, I dare say you could dive around in the top 3 gears if you dont mind slow acceleration times
Should it pass emissions ok for this era of vehicle (being that D1 was classed as a truck)? If you bribe the inspecting officer enough. In honesty Im not real sure what the exact emission regs for the D1 is.


On the plus side the block will physically fit into the engine bay but you will need to rely on thermo fans to get the clearance at the front of a disco.

I know the blokes at KLR Auto have converted a number of Rangies to the 4BD1-T.

Three of them drive Rangies with 4BD1-T engines.

Just an opener as I'm sure many have contemplated the same thing. Big-simple-diesel in wife-friendly-car.
I'm hoping that some nice people here could give a rundown of what is involved to repower with an Izuzu.

I have some obvious questions to kick off with for instance;
Can it be mated to a late R380?
Is the engine in the 4t trucks the same? (also see Q1)
Is it a heavy engine compared to the V8 for instance?

Lots more questions but off to the footy.

cheers

Hi Dan, As you obviously have these and many more Q's, Give me a call on (03) 6229 1102 BH and I'll give you as much help as I can in decidingwhich way to go. I am extremely biased on the 4BD1 into RR department so beware.

I will post in this new section a tech type discussion on the fitting and testing etc of my conversion, which I am extremely happy with. ( And so is the other half I might add....)
1) Yes, It has been done with success, and I nearly went this way but glad I didn't, as the venerable LT95 will last a LLOONNGG time behind this engine.
2) Mostly, the 3.9 Directinjection engine in the NKR etc is essentially the same except most have 24volt ancilliaries. I would go Ex county 110 if poss.
3)I haven't weighed it, but I have been informed the 4bd1 weighs about 360KG, and the V8 about 190Kg. (!)
4)My EX county engine with turbo is as quiet as a Tdi if not quieter. Especially a Defender Tdi! The truck engines are noisier and the nonturbo ones worse again. I can hear my Cooper St's above the noise of the engine at 110kmh easily.
5)Standard D1 gearing is not high enough, I would fit a 1:1high range LT230 ex 110 Diesel or Rangie 727torgueflyte(1985) and Minimum 32" tyres. There are some good tyre / revs/ calculators on the net, maybe a link here in the search section. You need to be about 2200Rpm at 100kmh for good fuel economy etc. ( That is for a turbo engine, and personally I wouldn't fit anything else)
6)My 4BD1 turbo with intercooler produces about 20% of the smoke of a tweaked 300Tdi, and will pull heaps harder from 1000rpm. I would say it would pass an emissions test, but check that you are allowed to fit an earlier engine to your Disco, as some states now won't let you go backwards in manufacturing years.(Stupid, as some early diesels have less harmful emissions than equivalent petrol...)

I think you are not alone. It is a revered engine in LR circles.

Hi Ron, when you come down for tea and bikkies, you will have to drive mine....a bit agricultural compared to a P38A, but enjoyable just the same.
As far as reverence is concerned, you may genuflect before alighting....

Hi Justin,

I've driven a few. I dound that I kept forgetting to put in the clutch at traffic lights, they just pull so well in the wrong gear that it was easy to forget I was driving a manual.

My local blokes keep telling me to convert the P38A to a 4BD1-T

I could even be persuaded to own one if the Isuzu would be a succesful transplant...

See you soon...

That would be a nice car then and I might be able to afford to run one.
