Don't do it mate. There is loads on here about it. Do a search and it's a compleat nightmare when people have converted there sports. Sounds like a good idea but it's not. Welcome too the site anyway and sorry for bad news. Thumbs Up MY11 Autobiography supercharged. Santorini Black. Monaco interior. Rear screens. Privacy.
Gone MY08 Supercharged HST. Java black. Ivory premium interior. Rear screens. Privacy. Missed a lot.
Gone MY04 Discovery V8 Petrol ES Premium. Awesome.

There are a whole heap of potential horror stories associated with LPG converting the RRS petrol engine - something to do with a lack of lubrication from LPG causing the valve seats to deteriorate. It can be done but to do it properly appears to be very expensive as upgraded heads are required.

see here for one example:
http://portal.jeengineering.co.uk/old/new-...gines.html 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Research the higher temperature burn of LPG compared to petrol and the damage that does to engine linings. If that doesn't put you off then nothing will.

You'll save money on fuel but a whole heap of problems will follow...

Do it but report back and prove us wrong.

Sorry to be a doom merchant but I've done a LPG conversion in a Subaru and it was a disaster long term... 2005 Range Rover Sport TDV6 HSE in Artic Frost. 20" 2010 HST Alloys, sidesteps, Hawke tips, plus minor bits and bobs along with a remap.

Bubbles...

Might I suggest that if you love the sound you drive it and enjoy it, not worry about MPG...

Life's too short.

We'll all be a long time pi**ing and shi**ing ourselves in geriatric care given the rate of medical care.

Does this apply to both the 4.2 S/C and 4.4 N/A engines?

People have been converting V8's for years - RR Classic, for instance. I have one currently, 135k on the clock, no problems - just as long as you run it on petrol now and then to keep the top end lubricated there should be no problems.

So what are the problems associated with the V8's in RR Sports, and do they apply to both the 4.2 and 4.4 V8 engines?
