Thread: V8 guys with big tyres.... i have some questions

The TD5 was and is a very nice diesel but can't compete for output and low noise etc with a modern jap diesel (and even less so a modern LR diesel; BMW 3.0 as in the Ineos etc). Have to have the blinkers off here. Cheers

And also funnily enough I thought you'd bite after my last comment and continue to plod down the confirmation bias path where it outguns, outbrakes etc.
No blinkers on here Scott, I did say others were convincingly quicker ( just not a triton or pajero sport) and so they should be after 20 odd years but there's a reason the little TD5 has a reputation as a tough and very tunable motor and that's simply that it is just that
The noise you mention is solely the unit injectors which really aren't that bad and I'd have them over CRD any day from a reliability perspective.
I suspect in another 20 years time there won't be many who'll remember the engine from a Triton, but I'm glad you've finally found the diesels you previously bagged on here 4 or 5 years ago to be better than you thought.
If it was all about outgunning outbraking etc I'd probably have something like a Kawasaki H2R

Apologies to O.P.

Shayne, if it's a keeper then you could always swap the diff ratios to 3.9's and whack in a couple of ATB's at the same time to increase the strength and capability while bringing back some grunt if you want to run that tyre size, just a thought.

. Why wouldn't i bite. Facts are facts. I will bite again. You may have forgotten i have owned and driven D2s since 2001 and still have a very well maintained D2. The Triton does outbrake it by a decent margin. Fact. Sorry I will go back in my box after popping out to inject some reality. And the only diesels I like are the current crop. Before then slow and noisy but I know that will upset you and others on here. To me, and i have driven them new and second hand, the fact that a stock TD5 (yes it can be made to perform but likewise modern diesels can be easily uprated) is noisy and slow compared to the modern diesels in all dual cab utes and euro diesels is unassailable but whether your passion and heart makes you prefer/love a TD5 over them, well that is another matter and one which i don't have any issue with. Between this and the dark side thread the blinkers on here sometimes are hard not to comment on. Cheers. Ps. The question of reliability of the 2.4 over modern LR diesels is another question for another thread but you know what my preference is based on my purchase.

Back on point, the 4.0 at 280,000 may be getting a bit tired for 32 inch tyres and the friction and gearing it brings mate. However there are a couple of things that can make them doughy. The first that comes to mind is the mass air flow sensor. The Bosch Motronic can get very doughy and not throw a code when the MAF degrades. If it hasn't had a new genuine one for say 80,000k or so then that may work. Cleaning them is hit and miss (and sometimes wrecks them even doing the cleaning cold). But if you use CRC MAF Cleaner and it gives it a boost then a new MAF is likely in order. The other obvious thing is leads and plugs but unless you run LPG you get a good run from good quality plugs and leads typically. Check the plugs though and a set of leads is not expensive. Apart from that they are a set and forget engine management system (bad 02 sensors will cause richness and poor mileage but not less power in my experience). If those things don't help then I would recommend back to 31 inch tyres and get ready for a hard decision on a rebuild or new engine/vehicle etc mate. Another option if you can't give up your 32's is as Discovery says above re new ratios and going ATB while there. Cheers

Yeah plugs are fairly new, haven't done leads (yet) MAF is under a year old. Mine died shortly after purchasing it and cleaning it with crc maf cleaner. Was a fun introduction to land rover ownership

Yeah thinking the 32's might have to go. Maybe something a little skinnier to reduce rolling resistance while im there

Shayne i know you are on 18's and I am on 16's but I find the sweet spot for both my 3.9 D1 auto and 4.6 (and before that 4.0) D2 V8's (manual) is 245/75. I have used 265 in lower profile and have a mate that still runs 265 on his D2 (ie all 31 inch OD) but 245 gives plenty of grip and doesn't tram track and gives modest rolling resistance. I found the 245 with plenty of profile to be the best offroad too. Hope that assists. Cheers

Further mate if you are struggling with getting the right amount of sidewall (tyre choice on 18's as a lot seem to start wide these days) when say dealing with a width of 245mm then you could grab a set of 16 inch (they come up for sale a bit) and go 75 profile. Cheers

It won't be staying on the 18's, they were a little bit of an experiment so to speak. I much preferred the 16's i was running so will be going back.
