I never make guesses on this stuff.. appreciate the business.
As to alcohol.. methanol is my number one choice. Look on the very first thread it says "Methanol Sources" do some reading through there and see if you can come up with a source.
If its not available to you, then the other alcohol to use is denatured alcohol(home depot, lowes, paint and hardware stores).
If you plan on rubbing alcohol, then buy the 91 stuff.. the least amount of the water, the easier to dial in the car. Methanol is the easiest to "figure out". Isopropyl is expensive compared to the others.
Lastly, pretty much any of the above alcohols can be used, including mixing thereof with water if your boost levels are relatively low. Example 20-22 PSI. The issues start when trying to go higher in boost with timing, leaning out air fuel, etc. Your knock sensor will tell you what the car likes.
