I'm not sure if they'll sell to the states

Well, it's not LPG but the Honda Civic GX uses CNG as its sole fuel source. Might be another avenue to research the technology as I'm sure they're not using mixers like the old Dodge utility trucks used to.
Cool topic.

LPG (propane) has a storage pressure of approx 120psi. A full tank of CNG (natural gas) can reach pressures approaching 3000psi.
Safety standards be damned, which one would you rather have under your *** when some moron decides to pile into your ride?

Forklift part work great for a cheap propane conversion. They just dont work very well much over 6000 rpm. Had a 496BB in a crawler I had That was 12 to 1 with a tunnel ram with 2 Impco 425's (flow 425cfm of propane, will support approx 450hp each) on Holley DP baseplates and 2 model E's. Propane mixes evenly with the air, so even with a tunnel ram it made great low end. Also, every mixer set up Ive seen is boost refferenced, so they work great with a blow through turbo's. Propane burns very clean (oil will look new with 10,000 miles on it) and burns at a low temp. Ive got a propane set up right now that will eventualy make its way on to an built old school VW stroker motor. Lower burning temps work great on air cooled motors. Its 105 octane and resists knock like 117 octane fuel.

Not a whole lot, but some. Lots of research before my first converson so I didnt screw up anything. Propane is pretty simple to work with. Search it on Pirate4x4.com, lots of info and guys who have done a lot with it.

Forced induction and lpg is a match made in heaven.
From my 5 lpg powered cars, i run 2 with boost (turbo and vortech)
One thing you have consider is that lpg doesnt like high temperatures(both intake air and convertor temp) , this reduces octane rating and revert lpg particles back into oily / sludge substance

Im sure the more advanced LPG systems are capable of more power and better mileage, and tuneability, but I like simple and cheap.
BTW, you can make your own propane kit from used/rebuilt parts from anywhere that services forklifts. Less than 200 for everything but the tanks if you are good at searching the net.

It is done here in Australia with a direct injection LPG or propane, On a LS engine it makes more power than a petrol engine. Here is your answer.

I fix forklifts for a living, right now our 4 cyl and 6cyl vortec Gm engines have direct propane injection. The system runs at about 15 psi, converted down from tank pressure. Ecm controlled, O2s, map, iat, ect, all the same sensors on the gas burner. Yes it is higher octane, but has a lower btu output, reduces engine output by about 10% compared to gasoline, requires about 10* more timing, and is very clean burning.

More info on liquid injection:
http://orgs.kettering.edu/orgs/lpgvan/SAE-LPG.html
BDE Ltd. of Lake Lillian, Minnesota did a bunch of the liquid injection groundwork and was later acquired by Schwan's, and became BI-Phase:

This was also used by Roush Industries on some of the Roush Fords.
