And there have been a few D4s around with blown motors (mostly 2.7s), so if it's within $10k of fitting a new 2.7 why not?

It wouldn't be, a territory motor can be bought for 2.5k or less, TDV8 will be 10k alone plus the auto, ecu and associated wiring.
Replacing a 2.7 is fairly cheap these days, the 3.0 doesn't have that luxury since the only donors are D4's and RRS.

Really? Aren’t the D4 2.7 known to be more reliable than the 3.0? And supposedly carry hidden improvements on the 2.7 that went into even the last D3.

I have been following this on facebook. I own a 2010 D4 3.0L which currently has 250000klm on it serviced every 6 months and still going strong. I also have a 2008 L322 3.6 TDV8 I got this a year ago with 97000 klm on it. I love the 3.6 TDV8 the problem with the L322 in this config is the terrible 490 kg payload. I have towed my 3.5t caravan with the L322 and it is a far better tow vehicle than the D4. The biggest issue towing with the L322 is keeping the speed down.

I was considering a TDV8 conversion to my D4 however I have decided to sell both the D4 and the L322 and buy a Defender 110 SE D300.

I understood that it was the 2.7 that has the issue with crankshaft failure -there's a recent thread specifically on that topic.

Yes in the D3 but not the D4 or the Territory - you said it was the 2.7 in the D4 and that is not correct. Even in the D3, 2.7 crank failure was pretty rare.

500 kg payload v. 860 kg in the D4. I know which I'd prefer!

Bern, the TDV8 RRS has heavier duty front lower control arms (don't know about the uppers), to handly the extra weight (which will also lower your payload). You might want to check that out for robustness and longevity...

I was crawling some hills around Dargo last week in our D4 3.0, and missing the remapped TDV8 RRS badly. The torque in that thing was outrageous for climbing and towing. You'll have so much fun!

Yeah it was more of a cost comparison.

Edit: and a D4 with 80,000ks for $32k seems like a very good price.

I got one for 7600 with 95,000 but needs a new engine still debating what I do
