Hi folks.
I have been away from here for a while, but thought I would pop back on to see what people have been upto on various projects, which as usual has sparked my interest in cool old cars again.
A few years ago I had a beautiful black Rover P6 V8 which I bought, sold, bought back and then sold again. It was a great thing but as a daily the V8 was too thirsty to live with. I know there is an emerging trend of people converting old classics to diesel power to make them more of a usable proposition, and was wondering if anyone has done a P6 diesel, or contemplated it, researched it etc. Any info would be much appreciated.
Would you run it rwd as the factory created it, using something like BMW/Jag/Merc power and box or go even more extreme and attempt to use a fwd engine and box from something like a Mondeo or Vectra?
If you have done one, know of one, contemplated one or even just want to drop an opinion, it would be good to hear. I don't want silly speed, just something that will sit around 70mph and give decent mpg, eg 30+ if possible.
Thoughts?
Mark

Why not. Modern diesels are so powerful you would probably get a car just as quick as a P6 2200TC with masses of torque. I'd be tempted to keep it simple and go for a pre common rail diesel so no electronics to incorporate.

I'de just convert it to LPG and run it as it is or drop in a later 3.9 V8

How about a 200tdi bolted to an LT77 box? Should be more straightforward than most swaps.

Agreed.. whilst the 200TDi won't win awards for economy or refinement, it keeps it in the Rover family, chassis mounts can be bought at a reasonable price, and there's an abundance of LT77/R380 gearbox ratios, gear selector, output shafts, and speedo drives available

If it were me, I would go for the diesel Rover 'L' series motor. As they are bomb proof, and easily tuned. I would prefer the 'L' series and an auto box. But when I looked into it, the only auto that I could find that 'might' have fitted was a three speed auto, and that kind of defeats the object of putting a modernish engine in one.

Might be controversial (I like them) but a VM diesel would be a straight fit using off the shelf parts from the Range Rover Classic. The engine mounts are in exactly the same position as the V8 in the RRC which should mean the same in a P6. There is also the SD1 diesel that used the VM.

if you've got the cash - you can get the freelander L series engine backing plate, which AFAIK, is the same as the K series bellhousing. Then it's a simple case of spending several hundred on a RWD K series bellhousing, and a Ford Type 9 gearbox. You've then also got to make mounts, without losing the water pump You've then also got a fuel pump belt that in most cars, will be near impossible to access. My love for the L is boundless, but converting to rwd is not something to be taken lightly

Would be cheaper.

L-series won't fit without serious involved work, and that's coming from someone with a 5 banger in the front of a P6

Wasn't there a P6 on here a few years ago with a Peugeot diesel fitted? (TUD or some code like that? (I'm not up to speed on Pug lumps). I believe because some LDV vans had the same engine that the ability to mate to the LT box is there.

Just been looking at the original question again, if you ran a 2000 or 2200, with a well setup aftermarket injection and ignition system you might crack 30mpg as you intended. Would be cheaper than an engine conversion. Not much of a twist though.
