Ok, I would like to know something about my mini. Its an 02
MCS with 105k, it is bone stock besides I got the mufflers cut off, and a weapon r intake. I want to put a 17% pulley on it, or should i just go with a 15%? (would it make that much of a difference?) but the only thing im worried about is would that be throwing to much power on the car with that many miles? Also i dont want to be replacing parts a lot and having to worry about parts breaking a lot. Would i have to get it tuned after this? Any help would be appreciated. Honestly I havent had my mini that long and idk much about them yet, so just a little help would be much appreciated!
