at what mileage is a good time to run a 55 shot of nitrous? and the motor at least to my knowledge was in good condition... regular everything. this was my girlfriends car and she only works 3 minutes away. and the owner who had the car before us was a 55 year old nurse. who lived at a convent for nuns. so i dont believe the motor was THAT h: tired......but i suppose you can never tell what an engine is going to do once you add something that wasnt supposed to be there in the fist place. but i would like to know, if any, which motor would be a good candidate for 55 shots. we will be getting a new motor and wanted something that can handle the juice....let me know
thanks.
