hi all, i have a '00z28 a4, i want to order a nos kit to go with my purchase of a single turbo. www.ls1motorsports.com, i have a relatively stock motor, nothing forged, i have z06 heads and a cam to be installed all at once with a flowmaster cat back. i want the nos at the same time. my question is, should i go wet or dry and what size shot will make a differance without killing my engine? do i need anything ignition wise to help? if you were in my shoes would you do the nos now or wait til i can work the bottom end of the motor? the turbo puts out 530 rwhp and some say a small shot of nos will not do anything but cool the air down more; this true?thanx in advance
