To be fair, the TD5 injectors dont go bad unless they've had a physical trauma. The pumps are much of a much between the V8 and TD5, bottom end rebuilds are irrelevant for the TD5, but needed for high km V8's, top end rebuild is irrelevant for the TD5 but relevant for even low km V8's, and then you also need to add the cost of repairing blocks with top hat liners in the V8 and looms + manifolds in the TD5.Quote:

Your choice in the long run!
The original query was between a diesel or V8 Disco II so between the 4.0 and a TD5..Quote:

As far as chips go, what Tombie and the others have said is 100% true comparing the 4.0 and Td5... you simply get a lot of bang for your buck chipping a Td5 ... the 4.0 provides very minimal improvement.
I think the popularity of TD5 chips is the simplicity of the upgrade.
Most of the V8 chips for the 4.0 like the Tornado that Mark Adams sells give as little as 10 - 15 horsepower extra.
My chip is pretty mild.. I am not looking to build a race car.. but it still gave me an additional 30 bhp and an extra 70 Nm of torque - in 10 minutes on a computer! (It was simply an ecu remapping - no hardware needed)and I am still getting an average of 12L/100km despite having a heavy right foot. (Average in my standard V8 was 19.5)
But in the end... What is right for me may not be what's right for Vogue,
Decide how its going to be used..... do the maths... and go drive a few and make sure you can live with your decision..

The availability of diesel is much greater than petrol in remote places. So I guess you have got it right, if you want to travel the outback it would be advisable to go with the diesel. Now if you just want to drive to the local pay and play, it does not matter what you have petrol or diesel.
Thanks Slunnie - Saved me typing....Quote:

I dont care either way, its not my money the original poster is spending and I now regret even typing in this thread in the first place.....
Oh and for the record...
I was rewriting the mapping in V8s in 14CUX and P38 Range Rovers and then early D2s) back in the 90's and early 2000's and doing custom programming of them.
Gains were never that impressive regardless, until head, port, cam, compression were altered...
We dropped doing it because the benefits were minimal without modifications to the engines.
Much of the gains were in smoothing the engine, not power or torque... So yes a few kw here and there but mainly a Placebo effect in relation to power.
But hey.... Who cares :D
Walks away......
Please stop....I have just about talked myself into getting a Disco.....you lot are talking me out again :o :p :)
Just get the V8. You know you want to.
If anything, V8 for the sound :)
I wouldnt chip my 4.0, because the gains are not worth it for me and usually end up pumping a fair bit more fuel down. My LPG D2 drives really well and its single point ($2,000 kit) and gets 19.5l per 100k in peak hour and stop start and a lot better on the highway - but its a manual.
Slunnie - take your point mate however having 16 plus gears might have something to do with the comparo truck motors doing their thing well - and of course the build of those motors is amazing strength wise. The fact remains that no other manufacturer of TDs in larger 4wds use such a small CC with such a big blower...the smallest I can thing of is the 2.8 Patrol motor....which has more than its share of problems and is a towing mole.
I guess its a debate that no one will concede on, but hey they are all landies (I was just correcting some of the earlier posts and adding some balance when I did my (slightly inflammatory:D) posts.
Just buy a landy!
Cheers
