Why bother to buy a V6 and LPG it..

Leave it alone and enjoy it as it is..

I agree with spongebob.. It will be cheaper to convert a 4 cylinder small engine car and maintenance will be more easy..

Although V6 can be converted succesfully, in the future problems will be more complex..

They are not bad to convert - worst problem is finding somewhere to put the evaporator.

What are the tank options? Could a tank be fited where the spare wheel is? The large cylinder tanks seem to rob a lot of space out of the saloons.

No tank - and by the look of it no tank valve.

Best off with a cylinder tank, light cluster would be blocked

Ah yes, never thought about that.

I can get a pro SGI conversion for £1300 if I take it to Yorkshire.

Or can do it myself for £600/£700.

I want a BIG cylinder tank.

My biggest concerns with DIY, are:

1) Where to mount the filler (I don't want to drill the rear panel, and don't have a shin breaker)
2) Running the gas pipe underneith to the engine bay
3) Certification.

Mount the filler in the plastic bumper like i have then atleast it will not rust, I have seen sooooo many cars with the LPG filler in the rear wing and its all rusty around it as the cut holes has not been sealed correctly atleast if its in the plastic of the bumper it will never rust, and as for small shunts in the bumper the attaching hose is a flexy hose.

I agree, makes the DIY fitment much easier

Because the LPG will pay for itself within the space of a few months
And then my fuel will be half the cost!

Open to all ideas though, this is a VERY nice car, and I want to do what's right for it, as well as for me

I'd say more like a year, £70 a month on fuel thats £840 a year. With gas mpg a little lower, id say it would be at least 1 year before its paid itself back.

You also tend to only keep cars for a matter of weeks sometimes.... so must keep it to get the money back. There is a 100L tank in the boot of my Elite, it does take up a considerable amount of space.

I would not bother LPG'ing it, just keep it and run it as is.

[Golfbuddy]

On the fuel cost question. If the cost of LPG is half the cost of petrol, when you take the poorer efficiency into account, and you spend £70 on fuel per week. The saving would be £35 times 52 weeks which equals £1820 per year. At a cost of £600 DIY you would recoup your investment in 4 months and would then start to reap the benefits. Lets assume that you can't use LPG all the time and that these calculations are optimistic by 30% then you would still start to see the benefit in 6 months assuming DIY and that the certification issues are not too costly.

For me, who spends about £70 per month on fuel, the payback would be too long at 2 years.

oopss your £70 a week i think? humm i'd still not bother to gas it

[M-Tek Performance]

boot space is a major consideration - its one of the biggest in terms of why im considering a diesel, which a chip, economy should be pretty good, almost at lpg standards??

I spend around £200-£300 a month on fuel..

[Crazydad]

I must agree with a few of the others don´t understand why you would want to change a great v6 engine

into a Eunuch, because thats what it will be like after the Conversion when using Gas

and as Golfbuddy  has said, 2 years before you start to reap in the benefits

If i had to think of my fuel consumption, then i wouldnt have bought a v6 to start with.

Sorry if this is answer is not liked, but just my opinion

Just to clarify, James's figure was £70 per week.
