I have had my nitrous kit installed on my car for over a year now. I must say that it was a breeze to install, didnt take very long...and I had no idea what I was doing. After it was installed and it was time to test...wow was it fun. I really have nothing bad to say about the kit at all. It dropped my stock ET 1.9 seconds!! I loved it and unfortunately it is up for sale because I am going naturally aspirated on the new GSR or TypeR swap. For anyone looking for a nitrous kit...I highly reccomend this kit. If you have any questions, feel free to ask.
