I visited "Diesellec" in Swindon today for a quote to do the new motor, they gave me this inormation :
Largest tank to go across the back - 85 litres giving 70 litres of Gas
50 hours work - would take 7-10 working days (they would want the car for 2 weeks)
Cost - £1800
Now Elite Pete had a quote for £1100 job done in a day ( Cardiff area ?)
and the guys who did it themselves put in - I think - 100 litre tank giving 80 litres gas and reckoned it was 2 hard days work and the parts cost about £800 in total..... if memory serves me
Now this seems to me to be a major difference in many areas .. or have I got it all wrong ??? at the moment this information does not seem to tie up ... especially the work loads .. just how do you do that amount of work in one day ... properly ?
I am still very keen to gas the new beast.

Mine has a 100L tank between the wheel arches, so it's perfectly possible to fit one in the saloon. 2 weeks sounds pretty ridiculous to me too. If they only do 1 car every 2 weeks I don't rate their chances of still being in business for very long.

Kevin, Markie and Me did my conversion start to finish in a day and a bit.. and none of us have done LPG installs before that ;)

Ask them what kit they're fitting too. There's a fair difference in price between the top of the range prinz stuff and the cheaper kits. Not sure how they compare performance wise but the couple of AC kits we've fitted must have clocked up a few miles by now.
I keep meaning to work out what the options are for doughnut tanks in my saloon and get the bulk buy moving again. ::)
I would have thought with a couple of guys working on it who have done the job many times it should be easy in a couple or 3 days.
Also, make sure they're not going to be drilling manifolds in-situ or any rubbish like that. (thankfully a bit of a challenge on a V6 anyway unless they go in through the plenum top.

I suspect it will be a romano.......Dieselec converted mine......i note their prices have come down.

Mine took just over 20 hours over 4 weekends approx
-
having done one now i wouldn't hesitate in doing another.
Me, doing it on my own i would budget for 5 days;
Day one: back end, paint and install filler and filler pipework.
Day two: Injector nozzels, injectors, wiring ECU
Day three: Vapouriser and water pipes
Day four: Front to back pipes (without a ramp this can be a real pain in the a$$) interior guage and switch and finish off any jobs that havent been done or that have cropped up.
Day five: test run, set up
I have most likely overestimated here, in reality if you were really getting stuck into it 3 days would be possible, so long as everything was to go in your favour.
If you were doing it yourself i would recommend these chaps:

James and i have used them, that kit he has there is just the front end kit, you will need to add a tank to that as well, i paid £705 for the whole lot, and that was with a 70 litre tank, although i wish i had gone for a larger one now, mine has done 6/7000 miles and everything is still good
I have seen a couple of people with 100l tanks, but have they got them in an Elite, don't forget you will lose a bit of space due to the bose amp in the back shelf.
If you need help there are enough people on here who have either done one or been involoved in a conversion :y

Day three: Vapouriser and water pipes
A day? This took about 45 mins :P :y
With two of you, you can do it in a leisurely weekend...

There are of course major assumptions in that statement ............... :)
You both actually need to know what you are doing, how to do it, and have the right tools and abilities.....
Just ruled me out of the equation on 4 counts !!!!!!!!!!!!!!!!!!!!! :)

I don't know whether this would be an issue or not, but if it is then I'm sure it can be moved easily enough. I would definitely go for the 100L tank in a saloon, as filling stations are still rather sparse in many parts of the UK, and any space left above or to the sides of the tank is pretty useless anyway.

100 litre tank fits fine in a elite

Knowledge, there is plenty of it on here
Tools, a half decent socket set, some torx sockets, a drill, hammer, tap and die set and a hole cutter, a multimeter, soldering iron and some heat shrink, that sums it up.
the kit i bought came with the LPGA guidelines for installation, this in turn helped me with the rights and wrongs, a good wiring diagram, all i needed was the Omega wiring so i could put the two together

Sammy hasn't turned up yet :(

I can't specifically reccomend a kit, but i have chosen a different ebay kit. Alternativefuelcompany on ebay. Also sells Polish kits like the AC kit. i'm told the AFC kit is a generation or two ahead. It doesnt rely on the lambda sensor for operation, it autocalibrates by watching the injectors entirely. (exact operation i'm not sure) and another interesting feature, it is a learning ECU so recalibrates continually to account for differences in conditions and engine/gas kit wear.
I have an Estate and i want the boot, so a 60L tank is going in the spare wheel well. FULL kit including tank is £650

Looks interesting, and sounds like a good price. If it's anything like the AC kit it will need a bit of a tweak on the road. autocalibration on that kit really only got the idling right.
Keep us updated on how you get on with that. :y

Hi The Doctor
I am in Willenhall just round the corner and would be very interested in seeing/helping with your conversion....they do a 4 pot conversion for £550 which would be ideal for my 2.2 estate. Any one else had any experience of these kits?

the price does sound good, i paid £705 for mine with a 70l cylinder tank.
The AC system auto calibrates based upon lambda readings, there is an initial set up required which i would imagine all systems need to have, but in the past when i have looked at the mapping sometime later i have found that the curve is different to the one we originally created.
I could be wrong here but i was led to believe that LPg requires the injectors to be open for a longer duration due to the differences in the fuel, would this not be an issue if it is using the petrol injectors as its source?
i wouldn't mind betting that when you get down to it the kits are not a million miles apart from themselves
and anything that saves money cant be a bad thing

Remember that the petrol ECU will have long term fuel trim values, probably individually for different parts of the fuel map, so if you don't get the calibration spot-on the fuel trim values will adjust to compensate. Then, if you run it on petrol for a while, they'll adjust back, so you can end up chasing your tail.

Injector duration is purely down to how rapidly the fuel is delivered through the injector, which, for LPG, depends on the vapour pressure and temperature and the nozzle diameter. If the fuel delivery matches the petrol injectors then the duration will be the same, however, the LPG system will apply corrrections based on the above parameters so it may not stay the same under all conditions of speed and load.

Just looked on the ECU manufacturer's site and, give or take a few details it does look very similar to the AC unit.
