Thread: Isuzu 4bd1T in an Italian Defender 110

As you might agree such engine in a coil sprung Land Rover chassis is what would have defeated Toyota Land Cruiser all over the world, but unfortunately LR fitted small diesels which could be ok in Europe but not all over the world.
However expedition vehicles from Italy to North Africa/ASIA have V8 gasoline and not 2500 td, even if vnt turbochargers and exotic set up produce big NM and HP.
Coming back to IVECO, this engine born in the '60's and it was turbocharger during the eighties, it has 110-120 hp at 2700 rpm, and torque is 314 Nm at 1600 rpm.
Please have a look at the following picture:

I take it the engine is indirect injection?

What is the redline? (Max rpm).

I thought a lot of IVECO diesel engines are actually FIAT design/build. I know my friend just had his IVECO Eurocargo engine fail, just out of warranty because one of the big-end bolts came off. $Au50,000.00 later...

The truck is used 6 days a week does big distances all over NSW, SEQ and Vic but carries volume with very little weight. Such that he hasn't yet worn out a set of rear tyres.

looks like it might be indirect as isuzurover was suspecting.... it looks pretty small it might just be the picture though and its completely different to a 4bd1 as you would probably already of guessed what size turbo is on it?

I never actually brouse any section as such just the New Posts, saves time.

I do not want to sound like I am repeating myself but my best mate has one(Isuzu that is), 2 other friends also, I just don't like them.
Nothing personnel what soever.---Life is too short for that.

I was posting and trying to help, posting to a new member from part of the world one of my parents is from. My post was shot down by a bearded(I presume) Isuzu follower that pointed out--quite rightly so that I was repeating myself and this section is sick of it.
Once again, quite rightly so.
My intension are honourable and this is hopefully meant in jest as its really just entertaining me now.

Get off my back now.Get on with your life and don't take matters so seriously.

Get a LIFE.

I have an Isuzu County AND a beard, and sometimes I make horrid comments in the FREELANDER section... Just for larfs

Fair suck of the sav, Freelanders really ARE an abhorrence...

AND the R380 is a toy gearbox. :O Big boys use an LT 95, (short throw shifter of course!)

See, lots of smilies as I am not serious at all....

turbocharger size is TA03, and to tell you the truth I don't know more about it, I'll get back soon with size/weight.

I wouldn't play around with a landrover gearbox especially since now your looking for more power...my lt85 is on its way out but that's with 400k and no rebuild im going to go straight for a 6speed isuzu box only trouble I've heard about the isuzu box is dougal having some problem with his but not sure what happened with that??? Does anyone know if isuzu ever made a 7speed gearbox ? Why I ask is usually the msa5g box has numbers on it that will relate to it being a 5speed but I was looking at this isuzu box that was what looked to be an old 6bd1 and the box had a number that consisted of 7 then other letters from memory.... Oh how I wish a 6bd1 would fit in a 110

I took a quick look at a 6 speed found behind the 6BD1 a few weeks ago and it had a 7 on it (plus two other letters and can't remember what they were) It was actaully a little shorter than the MSA5G (from memory about 15mm, but it was a rough measure). It bulged out the LT230 front output side, but from rough measurements may just clear. The 6BD1 flywheel housing/bellhousings are a larger diameter than the MSA5G/4BD1. Haven't looked at where the starter motor is on these flywheel housings - as it may push the starter motor into the chassis being a larger diameter. It was a seriuosly heavy box. The top seemsed very wide where all the gear linkages go, so not sure how it would go fitting under the transmission tunnel. Haven't got into looking further into it yet as I am currently in Asia for a bit.

It seems most of the newer Isuzu boxes have starter motors faceing to the rear causeing firewall issues.

I only looked at this as a bloke wanted to put a 6BB1 and 6 speed into a series 1 (you don't want to know what he was running before the 6 speed.....) My personal opinion is that a 5 speed with a wide spread and strength of the MSA's behind a 4BD1 is more than adequate. If you turbo it correctly you will have a wide usable torque curve, with wide usable gear ratios, that will hold gears with ease.

Silly question but my understanding of the 4BD1 is its also available as an industrial motor (gen sets compressors etc) in fact the Jaguar Rover Australia 4BD1 as fitted tot he Pernties and the civilian rovers actually has more in common with the industrial motor than the actual truck motor? So for the cost of an Injection pump with the mechanical advance for varying rpm this may open up a lot more options to out visiting friend?

The IVECO's are relatively unknown here the 4BD1 is the Moto Guzzi Vtwin of rover motors. It not nesscarily the best or the fastest but it does what it says on the the box is simple and will do it for a long time.

However it seems that Iveco is made for heavier truck than 4bd1t, as 8040.25 revs to 2600/2700 rpm only and it develops max torque at 1600-1700 rpm only...
I guess that 9.00R16 or 35" tyres would be needed to reach standard highway speed...
