If I was mad enough to consider spending $10k on a DIESEL shoe horning into a P38:o I would seriously be looking at putting an LS1 and a six speed manual in the old beast:D

Here's my 10c worth.. If you are going to diesel a Range Rover, don't put a 4 cyl in it! Smooth quiet refined power is what Rangies is all about! My choices would be LR Td5, BMW TD6 (I'm sure the earlier ones were mechanical injection), Or..... You go all out and do something daft like fit a Cummins 6Bt into it! It's been done into a Classic! 5.9 litres and anywhere between 130 and 350 reliable HP! The drawback is, being direct injection they are quite noisy. Put "Cummins into Land Rover" on youtube and you'll see what I mean! the 110 has been well done and sounds great on the road!! I have a 6Bt and Spicer coming out of the UK... Engine, Box and shipping all came in under $2500. It's going into my 101!! :D here's a pic of a 6Bt in a Classic (YouTube)
6BD1T in a P38a, what a thing that would be, is there any part of the drive train that wouldn't break? Be good while it lasted though
The problem is the dearth of suitable 6 cyl diesels. Outside BMW most of them are either pox or too big.
I've never heard of a 6BT in a classic, I've seen landrovers with 4BT and 6BT, the amount of lift required was absurd and likely illegal. The 6BT is about as refined as a 200tdi, the 4BT even worse.
The Toyota 1HD-FTE mentioned above is one of the few worth doing. One chap in Perth has got turbos and tuning for these sorted. Around 200kw at the wheels in a 100 series and burning completely clean with cool EGT.
The downsides (besides fitment) are 6's can't deliver the fuel economy of 4's. Those two extra cylinders seem to cost 1-2 litres/100km over a comparable 4 cyl.
I would take a 1HD-FTE over an LS1 every time.
A 6BT would be interesting, heavy brutes though.
I can't see why anyone would genuinely consider a GM 6.2 either, no idea about the antipodies, but they don't have the best reputation in the UK, and are positively hated in the US.
Lots of problems due to the fact it's a petrol block converted to diesel, whilst the output for the displacement is pretty limp too.
Which almost brings us back to the tgv 2.8, easy to get 175hp reliably, not to heavy, not to crude and 4 cylinder rego ( here in Qld anyway), there is still plenty of time before this project gets underway, but at the moment think that option might be the choice so far, 6BD1 would be a thriller though!
Td5.
