Nitrous Oxide...
Discussion
I'm tempted to have a bit more point and squirt entertainment in my Landy (which has a BMW 2.8 straight six in it). Nitrous appeals because it's easily reversible (the car itself is quite a rare item so I like the option of originality), and doesn't require any of the complex/expensive plumbing and custom kit that a forced induction conversion would need.
However the reports on the net are predictably filled with fanboyism and tall tales of mate's brother's dog's engines exploding with only small shots, so I thought I'd ask the wisdom and reliable experience of Pistonheads, as someone's bound to know more about it than a forum full of Yanks talking about it being 'rice or redneck' or some other cobblers.
Firstly, any experiences (positive or negative) of fitting systems to road cars, particularly ones with BMW straight sixes? Preferably first hand experience.
Any opinions on quality of different kit manufacturers?
I was looking at a wet, direct port system fitted to a suitably modified 'spare' intake manifold that I can just swap out if necessary, but I've also seen kits that uses Y-joins into the existing injector ports, with NO2 solenoids in one side and larger injectors in the other that are just 'upped' for the shots. Looks like an easy way of doing it, but I'd be concerned about fuel mixing under normal operational conditions, and I'm also intrigued by how the fuelling is controlled.
I'd be looking at window switching and WOT switching, but I've also seen ignition retarding devices. How does that work? Does it modify the signals being sent to the coils? Is it safer than just letting the knock control get on with its job? Any other kit I've not spotted that would increase safety? All I'm looking for is a 50-75bhp shot on a 200bhp engine, am I being overkill?
Finally worth pointing out that I want it to be reliable and minimise the chances of failure, but at the end of the day the M52 engines aren't particularly hard to come by so if it let go it wouldn't be the end of the world. What are the chances of that happening in a well setup system with a conservative amount of power gain?
Also, just to say I'm aware of the insurance implications and the vehicle is on the type of policy where I'm not really worried about it becoming 'uninsurable' (it'd be a hell of a long way from being the most modified car on the fleet). However if there's some legal aspect I'm missing then please feel free to enlighten me!
Any help would be greatly appreciated!

The reason why cars explode on nitrous, is because they plumb it in, and use it without the car being properly tuned for it. If you're going to do it, make sure you properly budget for someone that knows what they're doing to sort out some good engine management. 
I have no personal experience, and none of the tuning fanatics that I know have bothered either. Probably because the gain doesn't really outweigh the expense, aswell as the inconveniance of finding somewhere to put the bottle.

That's kind of the jist that I got, that anyone that ends up with a massive engine failure has gone in with the idea that it's 'cheap' HP and done it half cock.I have no personal experience, and none of the tuning fanatics that I know have bothered either. Probably because the gain doesn't really outweigh the expense, aswell as the inconveniance of finding somewhere to put the bottle.
As it stands it's the most suitable solution for me, as I wont be able to fit an intercooler in without chopping things about, and I don't really want to be ripping the engine to bits to drop the compression ratio.

In a Land Rover??
I'm 99% sure the Range Rover Sport is built on a Landy chassis...And for the record, a variation of the Landy chassis was used for the previous model Range Rover and Discovery's, but the current RRS and Disco use a shared monocoque on ladder construction that's completely different to the tin shed on girders that is the Defender

They also have a very good forum and will help you out with all you need: http://forum.nitrous-advice.org/
Electronic programmer is the way to go. Anyone who claims it isn't safe (I'm willing to bet) hasn't much of a clue on it.

Cheers 300bhp, what do you mean by electronic programmer?They also have a very good forum and will help you out with all you need: http://forum.nitrous-advice.org/

Have to say I'll enter the forum with some trepidation, the first thing I spotted was the username of a fellow V8 engined Porsche owner whose gained some notoriety on here and Rennlist
As 300's post WON forum looks a great place to start -

The G man has your answer.
Wizards of nos is owned and run by Trev Langfield, a man with more years in nitrous behind him than most, which makes him the man who can best advise you on meeting your needs.
There is no need to fear the gas, if your engine is in good order then the gas won't destroy it as long as you stick to the doses and settings that are safe for that engine. The wizards will give you all the advice and guidance you need on this subject, after all,Damaged engines are bad for business.

Thanks for the recommendation to WON everyone, I'll definitely bear that in mind when the time comes!Found a thread very similar to what your after (engine wise) - maybe try and highjack it

Thanks in particular for the link to that thread, very enlightening and just the sort of thing I was looking for!
Other option would be to fit an s52 engine from the m3, not origional but really cool in a landrover and also gives a good noticable hp increase 320 versus 19something for the 2.8. Bolt straight in (S52 is almost identical really) and the computer controlling the engine is the only hard bit to get working with the rest of the car, could prob get one and get it working for about 1500...
