I asked a guy from the MVD/DMV by my house, he use to work for the emissions station, and he says done worry about it as long as the motor is still a four cylinder as originally meant to be, but dont tell them anything unless they ask. So I just spent Frickin $165 for the mechanic to rip the thing apart to look for the CKF and to put it back. I am getting a P30 ECU from Password JDM.com as we speak, but it says its for a b16a2 so I hope it will work on a b16a3. After the ECU gets here, and we put it on, its just prayers from here because i dont want to spend another 200-400 bucks to let the guy put in an oil pump and a CKF sensor.
