131mirafiori forum

I've heard it mentioned that some of you guys are running LPG or natural gas on your 131s. Because it's cheaper than petrol in the UK. LPG and natural gas is yet to be cheaper than petrol here in the US but my father heard on the news that the price may be dropping because of some new way of extracting it.

This Saab 9000 throttle body I have could easily be mounted on a twin cam intake manifold using an adapter I could fabricate from a 1" thick aluminum spacer. Providing the bonnet will close afterwards. It also appears the throttle linkage from the cambox cover should bolt right up. Question is, is there such an external regulator/vaporizer that I could use and run a hose to the brass nipple above the throttle body? The red arrows point to the water jacket.

you don't need that at all. your 131 is fuel injected or carburetor setup?
you plan running on LPG or natural gas (CNG)?
in my part of the world LPG is 1/3 price of petrol and CNG (compressed natural gas) is 1/5 price of petrol. and it has nothing to do with new or old ways of extracting it, it has to do with oil cimpanies running your country!!!

I haven't got a photo at hand of the LPG setup on my car, but I'm using one of these throttle bodies.

With an LG B2 converter.

Gas only is the way to go, dual fuel is a compromise. The barbecue ring they put on top of the carbies don't work particularly well and airflow through the carb when running on petrol is reduced as well.

Yeah the oil companies set the price on natural gas. I think our biggest issue with the price of natural gas is allot of chemical companies use it to make other products. LPG is mostly used for BBQ grills and furnances for home use in the US. Where a natural gas pipeline doesn't run in front of a house.

My friend in Serbia was surpised that nothing in my house runs on gas. Everything is electric. because it's cheaper to run a stove or furnance off electicity since coal and hydroelectric power is much cheaper.

I'd prefer to use LPG on a car simply because I think it would give a better range based on the size of the tank. I know natural gas produces more BTUs which means more power but LPG can be liquified at a lower presure than straight natural gas.
 

I've seen this device called a BLOS mixer but it's rather large. It requires a 3" inline fitting which may conflict with the bonnet closing.

IMPCO is the gas conversion company over here and their products look the same as the company you have in Australia.

I just wondered since I already had a throttle body if it could be used on a LPG conversion.

if you're running a carburetor setup than all you need to do for LPG is to drill holes straight into carb and connect LPG feed there. if fuel injected than you need adaptor that goes somewhere between air filter and trottle body. both cases the lpg system is vacuum operated, meaning that engine sucks in as much lpg as it needs or as much as you allow it. lpg gets mixed up with air and goes into cylinders via intake manifold. you control rpm by increasing/decreasing air intake. normal fiat's carb will do just fine for that purpose. aditional benefit is that you keep bi-fuel option which gives even better range and flexibility. i'll take pic of that setup on my lada or 131  and post it here.
