What would be involved in LPG'ing one?

It would be a 2002 (newer shape) with the 4.4 BMW V8 lump, I assume tank(s) would be underslug at the back? With a smaller petrol tank installed?

What size would fit, is there room for 2x 80L?  :-/

Also no idea how easy it would be to drill the inlet manifold on the BMW lump, easy/hard?  :-/

Can you get away with a single varporiser or would two definetly be required?

The same as converting any car

Fairly sure there are vaporisers capable of supplying the fuel to run with a single unit.

Tank wise, think it's generally a 80/95L toroidal and small petrol tank... May be able to get a couple of cylinders in but doubt it'd be bigger than 60L each.

Manifold... Anything's possible Take it off and it's fine I'm sure

Google RPi Engineering... They know RR V8's

Oh... And budget about 4-5 times what you spent doing your 4 pot

At least, particularly if you want to go down the custom petrol tank route

If you just fitted a toroidal in the wheel well and kept the standard tank it's considerably cheaper

But whatever you do, make sure you research the kit properly as those BMW V8's can give variable results when LPG'd, sometimes being more expensive to run than on petrol It can be done very well, but research is the key

Give Teilo a ring

Yeah, why not. I'm sure the Stag 300 Premium is up to the job, as long as he can get hold of the other required bits. But make sure there's someone, somewhere who has managed to get one running right on it first

I'm considering tackling an XJR (straight six) later on this year once I have learnt from getting as many parts fo my install done by others fitting it myself so a RR install would be interesting reading for me

Its only a consideration at the moment, thats if we even get one.

If we went donut tank in the wheel well and a "standard" install, would we be talking sub £1k?

Not sure how many people have run stag on 4.4 V8    :-/

Well, given that a bog standard V6 install is about 700 once you've covered all the sundries, adding a doughnut tank (a 4 hole one. No point in messing about with a multivalve), an extra pair of injectors, uprated vapouriser and a V8 ecu kit with the extra loom connections, etc. I'd say that would take you over 1k before you go much further.

Cheers, guess given they at best get 15-20mpg the £££ saving would be fairly high, so repayment not a real issue.

I doubt it would be sub £1k (but probably sub £1.5k) and I would budget at a saving of 10ppmile like the V6's

Of course, if it's going to be used around town all the time then it's not going to be as good (lots of cold running etc)

if we kept it, 95% motorway runs

Looks tidy, but 2002 year is not the Jag Supercharged 4.2, but standard 4.4 BMW lump

Those prices are quite competitve, especially for 8 pots
