What do you mean by DIY conversion?

Think he means buy the kit and fit it yerself. Thinking about it for me series when it eventually gets finished.

I think you need it to be certified or you wont get insurance and the guy's around me charge almost as much to install as they do to test.

I know very little about LPG conversions, but judging by the number of posts on this forum about problems with LPG switching and the like, I reckon you need to go to a fully qualified installer and ensure you get a good warranty. Otherwise if it goes wrong in any way, a lot of professionals will wash their hands of it.

thats on eway of looking at it. another would be that a lot of the 'professionals' int got a clue and the faults are due to their lack of knowledge.
it wouldn't be the first business/money making idea that folk have seen as a get rich, fairly quick scheme but they lack the ability to properly install the equipment.
i think i'd be asking who's had it fitted?, who by? and does it work ok?.

Aye, Slob's right there. I struck lucky and bought my Rangie already converted and certified by RPi Engineering "RPi Engineering - Specialised Rover Engines" and they also rebuilt the engine as well

I think we is saying the same fing - its not summat yu wanna take to a back street garage - make sure its a company that has a good reputation fur LPG and make sure its a good warranty.It aint sumat that can be bodged - as enuf freds on here will testify.

RPI have a good reputation, to name but one.

that what yer need someone with a good rep or do it yerself if yer reckon yer up to it

Looking at the documentation that came with mine, the wiring is the stumbling block on a V8i engine for doing it yersen. 2 seperate emulator units so the ECU thinks the injectors are firing when they're in bypass mode, Lambda sensor into it's own ECU, dual chip standard ECU replacement for extra 10 deg advance when running on Gas, then the setup and configuration. All in Italian of course with bad English translation...

You don’t have to worry about any of that stuff on a Series 2.25 petrol.

How Difficult is it to convert? Anybody with a good mechanical knowledge should be able to convert a vehicle successfully. The most important things are to follow the guidelines carefully and be very methodical especially with the electrical connections.
Normally a conversion will take about two days for the first one. The vehicle will still run on petrol at all times. So, a conversion could be completed at weekends or over a few evenings. Under-mounted and multi-tank installations (such as on 4x4's) can take a little longer, but are still straight forward.
The only special tool that is required is a mini pipe cutter which only costs a few pounds - a good selection of normal mechanics tools will also be required.
There is a code of practice covering conversions, and it is essential that it is complied with. The contents of the code are common sense anyway and fitting guidelines comply with it. A copy of the code is available to customers from Tinley Tech"

Dunt sound too hard does it? Speshially if you're talking 2.25 petrol it's the simplest and cheapest kit, a bit over 400 quid.

You don't need to be certified to fit LPG kits, it is the LPG association that pushes the insurance companies to ask for certificates so they can then charge a high price to the LPG installers to remain in the organisation. Remember the LPG association main business is gas fires.
To become a certified installer all you need when their inspector comes out is a ramp a flaring kit and a gas detector, no mechanical knowledge required.
I had a Jeep Grand Cherokee that I paid a guy money to convert, what a mess it kept backfiring often taking the airbox with it. I took the car back and explained what was happening the LPG installer could find nothing wrong, how can that be when I had two expensive airboxes in bits.
So I took it to my mates Garage and he discovered the Lamda sensor was lazy and not switching enough, I fitted a new one and we then tuned the gas, result not more back firing. This would never have happened if the installer had the correct diagnostic equipment.
Last year I fitted LPG to my Range Rover, the first thing I did however was to make sure it was running correctly on petrol first. Now a few thousand miles later the gas is still running without any problems. I am running a V8 range Rover for about £20 a week in fuel.
We will be the last generation who will ever have the pleasure of driving a V8.

I had a lpg conversion done professionally to a 110 petrol, and had lots of problems with starter motor -changed 4- and the carburettor melted. I would not do it again

hi there,
does anyone know what the pulse connector and lamda connections are please

lpg kits to early vehicles is simple ,tank ,pipe ,vapouriser, gas ring on intake ,solenoids wired to cut petrol and gas piping is only coated brake piping and can be joined the same way pressure is only work shop compressor pressure lpg shouldnt effect starter must be other fault ,vapouriser and gas ring appro £70 each

i did one myself a while ago now about 2003, i bought the kit from heanor lpg conversions, it was a basic kit not the sequencial injection, i paid roughly £600.00 and i fitted it to a volvo 940, and basically i did all the donkey work fitting all the components, and then took it back and they tested it and set it all up on the computor, it ran fine and i sold it after about three years having made a bit of a profit as lpg was 35 pence a litre at the time, but yes you can buy systems off the internet and having owned 4 lpg cars not one insurance company has asked for a certificate.
