Just want to say before people think that I am trying to start a flame war, that this is one of my favorite message boards because everyone on here is truly enthusiastic about their cars. On IS300.net most people are just enthusiastic because they have a Lexus badge on their car and that modifying a car is just a way to diminish its value. Anyway this IS 300 makes 445.1 hp and 463.3 lbs of torque at the wheels! It's a bolt on kit from Toyomoto. Figure some people here might be interested. My Dad has an NSX and I keep teasing him that I'll beat his car, although I think the NSX is a rolling piece of artwork. Take care!
