I have created this as i didn't want to hijack James's thread about his LPG conversion, however having read it it got me thinking about saving some money.
Friend of mine owns a garage and was looking into this, we are looking at using my Omega as the mule to suss out how difficult it is....
from my point of view i have a couple of Q's

There seem to be a few kits on the market, 'mixer' and 'sequential' seem to be the most common, am i right in thinking this is the same as single or multi point injection on cars?

Are there any kits/maunfacturers that offer better after care than others, this is a very subjective question but again i am just trying to avout some of the pitfalls.

Testing, how do i find out who can test a DIY fitted system? is there the equivilent of the CORGI register for LPG fitters?

finally i have been looking on flea bay for an idea of price and saw this

any views?

Sequential kits are better......they squirt the gas into the intake of each cylinder.
Mixer systems, i think, just squirt the gas into the throttle body.

Any LPGA fitter can certify the diy installation. In theory how it works.....is after the lpga fitter gives you certificate.....he passes on your details to the lpga, who can contact you to come and assess the install and if its not upto standard, the lpga fitter who gave you the cert is in trouble.

Have a look here, if you havent already, might give you some more info

  cheers for the link....

i'm witing for the seller to come back to me on a cost for a sequential kit as well, have a feeling that will be a lot dearer....

If i could keep the cost the right side of £700 all in i would be happy

Is there a Road tax benefit to having LPG?

[Craig_R]

No you cant get any money of the road tax   which i think is really bad

[cem_devecioglu]

Definitely sequential system.

Before I do a bit search on that subject.

BRC kits here is #1 (most expensive but deserve the money)

Landi is #2

In my opinion LPG fitting musn't be done as DIY (may be will be opposed).Being an enginner I dont accept any amateur work on that subject.

But before you must be sure your car dont have any problem.Thats very important. Otherwise things will really mess up.

Better let it for professionals who do it everyday..Choose a big garage..Ask the project for your car..Ask the money.Ask the warranty.
 
See examples they have done..And watch them closely when they do the job..

Very serious subject..

Let the professionals cock it up

Let them route the harness next to the EGR so it blows the DIS pack, let them put the ECU in the airbox
let them try 15 different ways of connecting the evaporator until it works.

Hmm think I'll pass

thanks for the tip on sequential systems

Anything to do with my car is serious, i rely on it so much.

The garage i used is a small one, he is a very good personal friend and has many years experience in the motor trade, he is qualified and has spent a lot of time training apprentices, he knows his cars and the work he does is far from amature.
We are in the process of investigating the difficulties of an LPG kit, on face value there dont seem to be that many, those items that have been established as risks are being properly looked into in order to be sure we have an acceptable and safe solution.

The car has a lot of mileage on it, over 200,000kms/140,000 miles but it is serviced almost monthly, the plugs, leads and dispack were changed a few months ago, the next job will be the breathers and rocker covers at the same time as the conversion takes place.

and whilst i am not a qualitfied engineer i have completed several groud up brbuilds of cars and am very compitent with the understandings of an engine and fuel system

I tought things were different in England  

These things you tell is really amateur job..

But I'm really sure there are real proffesionals ..Also in this group is too many..

He was actually quite well rated and has done good jobs on Jaguars, but he messed up quite a bit on my last car.

It's always the same. Someone gets a good name for doing a good job, ends up with more demand than he can cope with, so recruits some knuckle draggers to do the work while he "supervises".

Thats exactly the same case here..

I'm a member of local lpg sites and I know many problems for incorrect fittings ,problems together customers,

many complaints ,damaged ECU units,MAFs etc.

Ps: forgot to add I was very close to go in court with a local branch who damaged the friends car..

Being an enginner I dont accept any amateur work on that subject.

I disagree, as long as the LPG install is certified by an LPGA approved centre before going on the road I can't see an issue. Most people doing a DIY job will want it to be a good one and hence take extra care.

That's like saying only a professional garage should change a wheel bearing, in case a wheel falls off if an ameteur fits it...

Hear Hear! There's too much talk of WHO can do what these days. My father has a degree in Electrical and Electronic engineering from one of the top universities, he's a Chartered Engineer, a fellow of the Institute of Electrical Engineers (or whatever it's called nowadays) and spent his career in the electrical / electronics industry. Yet he can't do simple wiring in his own house.

It's the standard to which the job is completed that matters, not who did it.

The rush to have registered people to do X,Y and Z is the result of lobbying by trade associations who like to create work for their members, IMHO. It must be stopped before we are not allowed to lift the bonnets of our cars any more (let alone build a kit car, for example).

The IEE is now known as the Institute for Engineering and Technology

I completely agree. This whole LPGA approved nonsense is all about making money and very little about improving safety. They are a self-appointed group with absolutely no regulation whatsoever, and I have heard plenty of horror stories of "LPGA approved" installations that were unreliable, poorly fitted, and even some that were considered unsafe. I have an LPGA certificate for the dual-fuel system in my car (which was fitted before I bought it) but that made no difference to my opinion of the car or dual-fuel system until I'd had a good look at the install myself. All I'm saying is that LPGA approved is meaningless, judge only on the quality of work and reputation for after-sales service. The only way is to ask around (try some online forums) as get as many opinions as you can.

Completing one job in a proper way is a matter of knowledge,practice and necessary equipment.

if you think you or someone who have all of those complete (this means profession) then  can DIY.
