This is by no means an easy conversion, or common, I only know of a couple, and neither are finished as far as I am aware.
Probably the furthest developed so far is this one.

But also sowen is just about starting his conversion now too. http://www.classicroverforum.com/viewtopic.php?f=21&t=5288&start=270
I intend to do roughly the same conversion, although I keep rethinking. One consideration is that the rwd gearbox and various bits required to attach it to the engine aren't easy to come by. I would be tempted to either stick to the standard P6 engines, or go for a simpler rwd engine/gearbox combo, maybe an Omega 2ltr/2.2l engine would be an easier find and fit. But probably more expensive.

Why do you want to convert it to 16v? Have you ever done an engine conversion before in anything? What do you want to achieve by replacing the standard engine with a non standard engine? Are you prepared to possibly irreversably modify the vehicle and significantly devalue it? Do you have a workshop, garage or off road space, enough free time and funds to research the conversion, buy the parts required and physically do the conversion yourself?
Sorry for being a little pessimistic but the amount of times people start these conversions and projects, and either don't finish them because they run out of time, patience, skills or money then end up scrapping what was a perfectly good car in the first place or flogging it on ebay for a significant financial loss is very common. There's plenty of information on the internet of people who have converted the Rover 16v M/T series engines and fitted them in rwd cars if you have the time and knowledge to start researching it in the first place. The old mantra of if you have to ask springs to mind :?
I've had my p6 for about 8 1/2 years now and have constantly been changing my mind with what direction I want to go with the project and have often been lured away with other projects so it has taken a very long time and I still haven't got much to show for the ££££'s I've thrown at it and the long weekends, evenings and lunchbreaks that have gone into it
So do you really want to do it?

Ah well, I feel better now, I've "only" been doing mine for about 6 years.
My Land Rover project is 12 years and counting
I am imminently about to convert it to 5 speed and permanent 4wd which I was told many years ago would not work because the gearbox is too long and the uj's in the front axle won't last long. I've got to the point where so many people say things won't work or don't fit so I don't directly ask for advice anymore, just lots of research and then go out and do it anyway 8)

Everything is possible, you just need a bigger hammer......
I like my man cave and selection of big hammers

Everyones got different skills and experiences, it's just there are a lot of people who's plans far exceed their realistic abilities, but then again, sometimes you need a challenge to improve and learn new skills
Have a read through this site: Kew Engineering
It's directed at MGB's, but most of the principles apply of converting a fwd engine to rwd. The best plan of attack if you really want to do an engine swap is to physically get out into your local scrapyard with a tape measure and size up suitable donor engines. For the Rover M/T series swap, you really need to find a Sherpa van which has the older O-series engine fitted with rwd gearbox and it should have a suitable flywheel to match the injection system crank trigger set-up, although I believe the Perkins Prima powered Sherpa vans can be used although I doubt they would have provision for the crankshaft trigger on the flywheel. I believe the oil filter will foul the front crossmember and a Land Rover Discovery mpi inlet manifold will be required to point the throttle body forwards to clear the heater. There would probably be many other small issues but I have not physically dropped my M series engine into p6 yet so cannot say too much yet.

One thing I've considered, due to the construction of the M/T series, it has an engine back plate between block and gearbox, in theory you could make one of these to suit almost any gearbox, leave the standard flywheel on, and then you'd need to find a clutch driven plate to suit you choice of gearbox and the rover clutch cover. I admit it's not a 5 minute job, but does open up the gearbox options.
Ford Type 9 or MT75 for instance, or even the stock rover 4 speed, but that would just be daft.
I still say the best (read easiest) option is to just take a rwd engine and box from a suitable donor and drop it in.

The original Rover 4 cyl is also built like this. But then how come no one has taken this opportunity to mate the engine with a different (5 speed) box? As far as i know, everyone is using the Rover bellhousing by mating it to the new gearbox with an adaptor plate.

I think that if you take Simon's advice and start with a tape measure, you'll quickly find that very few engines will fit unless you chop a lot of metal out of the engine bay.
The cross member means that nothing with a deep sump at the front will fit. The gap between the engine mounts is extremely narrow at the point where most modern engines are fattest.
Why not have a think about converting your existing engine to EFI instead? Start with a Google for Megasquirt ...

I measured up a Mondeo Endura engine (similar to P100) once when I had a spare, engineless P6. There was no way it would even come close to fitting. It was too tall and too fat. Besides, have you seen the prices of Sierras and P100s recently?

It's on my "To Do" list, I'm not happy with the LT77's I've seen mated to the P6 bellhousing, but finding an LT77 one that will roughly align with the P6 engine hasn't been easy. I've tried a couple, but a new contender has just come to light so I'll be trying to get one of those to have a look at.

Doh! Sorry Chris, I forgot it was that engine.chris said:
