P38 tds to td6 conversion

Hi all ?‍♂
I'm an irish mechanic with a p38(auto) at home I'm abroad at the minute but due back in a couple of months anyway as the title suggests I want to replace my tds with a td-yes (td6) .
Has anyone here done it before? if so what is the easiest way about it? Complete loom and ecu's? or wire new engine control module to current harness or is there conversion units and looms available? I was hoping to make adapters and keep current gearbox ?
Any help from anyone who HAS made the swap would be good.
Please no keyboard warriors ???

No advice, but you're going to replace the 6 cylinder diesel with another 6 cylinder diesel?
It has been done before but only with a manual gearbox. If you do a search a couple of examples should come up. The auto box needs info from the engine ECU to change smoothly, so it will not work if you change the engine. It would be easier to start with a manual diesel p38, so there isn't a problem with the pedals. The engine is a bit longer and the sump needs to be cut and welded I understand.
More easy will be swap with BMW common rail engine. 3.0d. No big challenge there only oil pump and oil pan need to be adjusted/remade.
Really nice powerful and strong engine.
I was talking about the BMW M57 engine as a replacement for the M51.
Ah, so you want to builda, reasonably new, 3.0 V6 diesel from a Land Rover in the P38?
Have you done one before ? Just wonder about the maf sensor and diesel pump I can't amagin the tds engine ecu is going to have a different map and might be working of an analog signal for crank and can shaft sensor ?

No not a v6 that tdv6 is a horror . The m57 is just a lot frontier than the tds
Ya I had been looking a few seem to have done the auto box but very little info on it.

Yes, done and still working :)

But just to be clear. You change everything engine, engine loom, ecu and all engine sensors. You need to remove the M57 immo or you need to have a key and ring together. The only thing that is easy is that the engine is very similar to M51 and you can physically put together with gearbox.

Everything else is a custom made, the biggest issue is a oil pump and oil pan.

But at the end you will have a strong and powerful engine.

The earlier versions are better (190-204 h.p) with a standard bosch injectors. Next are with piezo one and the are more expensive. With this old and high mileage engines, soon or late the injectors come to be a problem and need to be rebuild.
