Well...it's a 4th gen with a VQ30de. 205 is a little small. You should be running at least 215 for tires. As far as specifications go, I believe the VQ30 is somewhere around 190hp and 205ft/lbs of torque and its a 3.0L. For things to look out for, pull your codes and check for a knock sensor code. It is a ghost code and will not trip your SES light. It retards your timing and gives you poor performance and gas mileage regardless of the octane you put in. There is a plethora of available info on these cars available on the net and on forums. A great site for keeping your max on the road is
