Hi Guys,

I am contemplating putting an end to my L322 woes (hopefully), by upgrading to a 2005 Supercharged Model. My logic is that my current car needs a possible engine and gearbox, plus I would like to facelift it, upgrade the navigation, and fit RSE.

I have found a Supercharged model with a slightly high motorway mileage, in great condition, which would probably not cost much more to trade up to than doing all of the above.

Is this a no brainer? What are the Supercharged models like to own? Also, does anybody have one with an LPG conversion, since I would get this done. The dealer will get a Prins kit fitted for me, so I would have the advantage also of a high quality newly fitted and warranted LPG conversion.

I must confess I'm really tempted, since it is my ideal spec. I have read some mixed reviews of Supercharged L322's on LPG though.

Any advice would be very welcome.

Cheers,

there has been a recent thread about s/c's not being suitable for lpg.... ... - .- -.

You can LPG a SC but it needs a good flash lube system.
JE have the knowledge.

I was advised against it by two owners who let me know their woes.

The 4.4 BMW is a better gas bet.

I note that the SC RRS is fine on gas though?
Have met three owners at my local Indy gas shop who say they have had no issues.
Odd as it's the same engine isn't it? 15MY SDV8 Vogue SE

JE will do it for 6k but you still may have problems so JE say. You will find indy's that will do it for a lot less but to be honest it's a lot of car to balls up if it goes wrong. Yet to find a perfect installation. I don't think log will ever run perfect on a sc. I was going to do mine but at 6k it ain't worth it. As mentioned if ya wanna LPG a ffrr get a 4.4.

Cheers

£6K is a lot of gas miles, even in an SC. Ian

Crazy to even contemplate LPG with an S/C just enjoy the engine or buy a diesel.

I have a converted 4.4 already, that's what I want to upgrade from. I'm far from convinced that the 4.2 supercharged can't be converted without issue. I've read plenty of posts by people who have converted successfully, and whilst I've read about some which haven't gone wrong, I'm sure that once a company has done a couple successfully, there is little risk.

As for cost, I'm looking at more like £2k for a full Prins conversion by one of the top converters.

Also there appear to be plenty of Supercharged sports which have been successfully converted. Logically if you can convert a sport without issue why not a FFRR? I believe that it's possibly just taken the LPG installers time to learn how to do it successfully, and unfortunately some owners were caught up in their learning process! Range Rover-less at the moment - Pining!

Well since getting my SC I was under the impression that JE are to people to speak to so when they tell me 6k to do it and that i still may have probs so dont bother I'll listen to them. But as mentioned for some reason the RRS SC seems to convert well so that is confusing???? I was recommended to go to a local installer and when i spoke to em he explained that it can be done but it is tricky. Total cost would be near 3k but car would be perfect. Ok i thought so i popped down to meet him before christmas to talk stuff over etc... he then explains that all LPG conversions have niggles and some never go away but with the fuel savings its ok to accept it. Engine lights on all the time, possible that the SC will never run at full power!!!! WTF!!! so much for a perfect install. The problem is i've yet to speak to two installers that say the same things each has there own opinion on how the SC should be done so thats what makes it confusing. For me there was just to much risk involved. I've waited to long to get a FFRR so i aint gonna mess it up by trying to save the pennies!

That being said if you do get one and get it converted and all is good and running smooth let us know

cheers

From an LPG forum where a member is looking to convert a Jaguar:


Went along to JE motors so they could see the car, and guess what!
Did not want to do it!
They said I would have lights on and of all the time, it would run but with problems.
They said they would contact Prins to see if they could get hold of the Jag soft where they would need to do it, they have land rover but it is different.
They know what they are doing that is for sure, they have a 4.2 RR with 460 hp demonstrator!
but it is good to see that they don't just talk a good job with out back up.
Lets wait and see what comes up from prins.

Here's the link to the forum:

Am I right in thinking that FFRR SC, RRS SC & S Type R all share the same 4.2 SC engine? So if one c,an be done all can be done? I have a installer that's just round the corner that has done many s types no problem and says my SC will be no probs

Cheers

Don't forget the XKR......

Oh yeah forgot about the xkr. Still very confusing tho why these have been done but the ffrr sc seems to be 50/50 wether it will be any good or not.

Spoke to a very helpful chap at greenfuel today. Apparently there would almost certainly be issues within 30k miles if fitting a standard LPG kit. They get around this by adding in valve lubrication injection. They haven't had any back which they've done on this basis. They did have one of their early installations back with premature valve wear, and so they paid for the hardened valve conversion offered by JE.

So what they said was, probably save around £1,800 per year based on 15k miles, conversion cost £2,700. Probably well worth doing if I keep the car for a few years, also may be able to avoid the VAT (included in price above) if the dealer gets it done for me. So payback within 15 months. Range Rover-less at the moment - Pining!

That sounds interesting. Please keep us informed as to how this goes as I would be interested in getting mine done if there were no problems.
