[berz]

im about to give up my clean babied coupe with a ka motor twin cam , s14 seats hks grounding kits and many more mods. the person who is trading his bone stock sr20det to me is a kid who just got the car and now daddy wont let him drive it. my point is the car has a bit of out side damage to the drivers side door pannel but the motor has been rebuilt the turbo is at 7 psi he never installed a boost controller and the motor looks cherry. he wants to trade for a bone stock car . his tags are due in june and the car willl probably need to be smogged. im going to his house to test drive the car and see if its what it is. the kid and his bro seem honest but im skeptic. help me with some advise with my situation. should i trade it or do a swapp myself i dont have pics of my car this computer is new soo if u can check out user s13poop photo galllery u can see my coupe . thanks alot guys
