i was planning of having someone do a complete propane conversion meaning that the car could only run on propane and the gas tank would be removed and I was thinking that the propane tank be mounted in place of the stock gas tank.

what if i was to buy an 07 vw gti? It is a 2.0 turbo with 200 hp and there are companies out there that have ECU programs specifically tuned for 100 octane race gas. Will this be a good match for a propane conversion.

so lets say i have a 2.8 V6 that has chip tuning and exhaust and the hp is about 190. and the car gets about 20 mpg. With LPG ill have about 180 hp and get 18-19 mpg? (with a compression ratio of 10:1)

Does anyone know of people who can do the conversion for me in NY? like a shop that specializes in it? thanks

I was going to buy a 96' vw jetta 2.0 (4cyl) and run it on butanol, but the stuff costs 3.75 per gal.(i thought it was .85 per gal) anyway, it seems like propane is the way to go. How much would a conversion like this run me and if possible just give me a general run down on running propane(I'm new ...

I was thinking of buying a 1997 jetta 2.0 manual as my daily/winter beater and possibly run it on some sort of alcohol. I've heard that butanol is cheap but has a very low octane rating. I'm pretty new to this stuff, so i just want to see what people think would be the best alcohol to run. And does ...
