Anybody done their own conversion and how much did it cost to do?

Only curious, i bought my MIG already done although i have been told that the kit fitted to my car wasn't a multi injection kit but a standard kit, that was a guy from an LPG installers garage though.
Saying that i haven't had any problems with it.

there are a few of us who have done our own conversions all with differing cost.

it;s safe to say it is possible to do the lot for less that a grand and it can take a few days to install and then a little time to map the system to suit the car.

it sounds like you have a mixer system, the more recommended type is the sequential system, the mixer system will work but seems to throw up more issues that a sequential one

SGI conversion on mine, with all new front end under bonnet parts, £500. Works a treat

An SGI conversion might well be a good move. You could just replace your mixer system with an SGI front end. 500 quid minus what you can sell the mixer front end for on Ebay

SGI - sequential Gas injection. Not to bad at all to fit

[Kevin Wood]

An SGI system injects gas separately to each cylinder's intake by calculating the required amount of gas and opening an injector valve for the appropriate amount of time to deliver it.

A mixer system uses a largely mechanical device, sometimes with electronic control, to deliver the gas based on the airflow into the engine, and it does so at a single point near the throttles. This doesn't give anything like the same control of the gas mixture.

Think of it as the difference between a carburettor and fuel injection.

What is the realistic miles per litre or gallon you get?Mainly for city driving because thats what i do most.

generally get 10% loss of MPG on gas compared to petrol.

Mine too!

[Faz]

so you would actually get less miles per galon but you save on cost of fuel.How do we know once we convert Gordon wouldn't hike the taxes up?As it is I could probably get the 500 pounds back whithin a year or even less which sounds good.Could any one help me with the items below

1-Is it worth having it on a car of that age with 120000 on clock?
2-once fitted can it be removed and fitted on to other cars cheaply enough once this one has had it?
3-Will running things on Gas wear things out quicker than normal and therefore costing more in repairs?

[Kevin Wood]

1-Depends how long you're likely to keep it. Plenty of life left in an Omega of that mileage, if you're still going to own it in a few years.
2-Yes but you will have to get it certified again, might need to replace pipes and seals, etc, and any other bits that don't meet current standards when you re-fit it.
3-If anything the engine gets an easier life due to the reduction in carbon and acids deposited into the oil. On some engines the valve seats can have a hard time but I don't believe the Omega suffers from this.

We don't i'm afraid, he's a law unto himself

1-Is it worth having it on a car of that age with 120000 on clock?

Omegas will do a lot more than that, thats why taxi drivers love them

2-once fitted can it be removed and fitted on to other cars cheaply enough once this one has had it?

It can but not easily

3-Will running things on Gas wear things out quicker than normal and therefore costing more in repairs?

In a word... No

Thank you all for your detailed answers just one final question what is the cost of fitting one in and by the way what will happen to my petrol tank?

it'll have petrol in it for longer
