Audi FSI

[stbb]

Has anyone converted one of the vw or audi fsi 2L engines. turbo or NA. Im looking for a replacement for my 4L Discover and the above engines seem to get about 35 ish mpg on petrol so should give about 58 to 60 mpg on gas. Any problems with above conversions to look out for. Thanks

I assume you mean equivalent running costs to 58-60 mpg. If they will do 35 mpg on petrol, they'll probably do around 28-30 mpg on gas. It'll cost you less but you're still actually using more fuel.....

Sorry, but this is a pet hate of mine. I've seen adverts for Range Rovers and Discoverys where people are saying 'it does 40 mpg on gas!'. No it doesn't, try putting 10 litres of gas in the tank and then expecting to it do an 80 mile journey. It may cost the same as if it was doing 40 mpg on petrol, but it's still only doing 20 mpg (and you're going some to get that sort of mileage out of a Land Rover V8, I reckon 15 mpg is more to the point).

But to answer your question. Is this the engine with the odd direct injection system (similar to the Mitsubishi MPi)? If it is then the general consensus seems to be that they can't be easily converted.

Hi, i did mean equivalant mpg. I belive they are all direct injection. Im toying between going back to diesel or converting another car. Out discovery is getting about 27 ( equivalant ) and piccaso is getting 60mpg. I know i can get about high 40 low 50 out of passat or audi tdi and was wondering if it was worth it keeping with lpg now prices seem to be sorring and petrol/diesel dropping. Im looking for comfy car with mid 50 mpg once converted ( equivalant).

I take it you mean a used car. I would look at the reliability tables/surveys.
A petrol Avensis,, or a Mazda 6.
If you want longevity and reliabiliy then a petrol c180 merc. Good luck.

Ive still got the LPG kit from my old car and am toying with the idea of converting something else, would do it if I got a really nice petrol car cheap and reckon it works out a bit cheaper than diesel, but Iam happy with my mondeo diesel at the mo and prefer it because its less hassle than LPG (lack of filling stations, conversion issues, having to start on petrol etc)

I know what you mean. My landrover is a pain, 170 mile range on 60 L, prices at home 56p l and away up to 77p L. At least with diesel you can fill up at at almost any supermarket and be withing 2p of home. Im im still convinced lpg is going up the same price route as diesel, cheap at first then now 3p l more than petrol.

The reason diesel is more expensive than petrol is because of the increased duty that was applied a couple of years ago. Up until the current generation of diesel engines they had been nothing like as popular here as on the Continent so there were a lot less diesel powered cars about. Once diesels started to get vaguely civilised (but still noisy and smelly with horrible driving dynamics as far as I'm concerned), more car owners started to buy them. This was a worry to the Government because they used less fuel than the equivalent petrol engined car so they were losing out on revenue. The answer was to increase the duty rate on diesel so although you use less, you pay them the same amount.

Unless the number of LPG powered cars on the roads increases to at least 10 times the number there is now, the same won't happen. Even then it would be doubtfull as the Government have already stated that the duty rate on LPG is frozen because it is a 'clean' fuel and they don't want to be seen to discourage something that they can use as an example of how they are trying to reduce pollution.

But, if you are happy driving a diesel, good luck to you.

diesels are far more complicated these days and as a result break more often. then you will find that all the cost you have saved on fuel will be spent on putting it right as parts are expensive for modern diesel engines.
A modern diesel engine has a lot more to go wrong than a modern petrol engine. used to be the other way around and diesels were virtually indestructible. the tolerances within a diesel engine these days are miniscule.

Direct Injection Engines like the FSI are sometimes convertable with the right kit and installer.
Tartarini, Zavoli and BRC offer sequential systems especially designed for direct injection
Often depends on the exact engine code.
