    LPG or CNGV can it be done?

    I have a 99 discoII and was wondering if anyone knows how to convert the 4.0L V8 to a propane and or compressed natural gas? Just thinking about doing this? I have not seen this conversion only threads on desiel conversions. I did see something on Wheeler Dealer when they had a Ranger Rover but they did not go through with it. I do belive it was to expensive for the show. Not sure if they do this in the states but I would be willing to do this conversion!!

    All you have to do is buy a kit that will convert your rover to lpg.

    The only problem is that you have to have an EPA certified kit to convert a vehicle in the US. The above kit and Land Rovers in general don't appear to be on any eligible list.

    good to know about that list I would venture to say that i would be willing to try the LPG but I could not find a price or anything like that. Also the web site looked to be based over seas? Not 100% sure but was wondering if there is anywhere in the states?


    Thanks for the help

    ive done a few kits on various cars, a couple of audi's bmws and kits on a rr sport and one on my lr3. the kits i use are the sequential injection kits. if you want i can post pics. a dII's injection system is more forgiving than the lr3 as far as how well the tune is. your mileage stays the same but the power is 85% of normal. the kit i use lets you set it up so if the rpms raise past a point or throttle position is greater than user preset, it click back to gasoline. this is handy when pulling or getting on the freeway. the epa kits suck and the majority of the install companies i talked to are hillbillies. its good to have it inspected after you have it up and going. you want to stay safe. as far as the kit goes the majority of the kits are 80% plug and play (mostly it interacts with the fuel injector plugs) and you drill little nozzles into the intake plentum. the nice thing is the factory computer should self tune once you get the cng injectors close.
    with the engine cover on all is business as usual.

    LOL - I was just about to ask how little power you're willing to have and now I see the drop is only 15% less power. Since the 4.0 is almost too small for the scale tipping Discovery... be prepared to mark your acceleration with a calender!

    I imagine there'd be a good deal of information on the UK forums, seeing as it's a more popular add on across the pond. Try Lr4x4:

    Edit: RPI engineering has some useful info as well:
