As this question was answered on another website: "can you mow your lawn with scissors?"
yes, but it wouldn't be practical. currently, no companies make a 2-speed conversion kit for the firestorm, so you would have to craft your own some how. just stick with one speed. if you want high top speed, pick up a jato.
I'm sorry, but its completely practical and very easy to do here is a link.
There are more vids of the 2 speed firestorm by me. It is now a novarossi 528 xr 2 speed firestorm vids should be up tomarrow.
If still interested i have some how to 2 speed a firestorm videos on youtube. It does make a very big diff. and to date have the only one that i know of. This truck has been 2 speed for about a year and a half. about 4 days after they were released so i know it was the first one. I finely decided to not sit on it any longer so check out the vids and if you have ANY trouble send me a vid and i will show you how to get it going. GOOD luck and post a vid. My truck is now a novarossi 528 xr 2 speed firestorm. I just did the conversion this weekend so i will post some vids tomorrow on youtube user chevyguru77 or search 2 speed firestorm.
