+1 as I and two other club mates are having a lot of fun with our G-20 gassers. I also believe, if you want to get a gasser, that you get one specifically designed for it.
IMHO, you are better off to sell your nitro and to apply those funds to getting a proper gasser.
I found the difference in cost to be about the same as what it would have been for a conversion, but now had a clutch system that was designed to take the extra torque of the gasser engine and a frame set that was better designed to take the extra amplitude of the vibrations of a gas engine.
