Hopefully some time next week I will be ordering the N20 Powershot Carb. Kit-which runs for $410 from Mustangs Unlimited. The motor has 230k on it and still runs strong, but it will be rebuilt sometime this winter. I figured that if and when the nitrous blows the motor up, it will be a good time for rebuild. I also figured in that when the motor is rebuilt, I will have the nitrous available to use again. My motor should handle the 50-125 shot with no problems for at least a couple of months, right?
