im wanting to install nitrous on my 01 s4. i have a nos wet kit from my other car i want to use. i would use a microswitch for wide open throttle. my questions are, where do i tap my fuel? do i need an adjustable fuel pressure regulator and or inline fuel pump? does anyone have any info on someone whos used a nitrous setup on one of these? im stage 2+ and dont want to go stage 3. id rather hit with a 75 or 100 shot when i feel like racing. i think it would be just as fast or faster.

 

probably not faster than a stage 3, but look over on Audizine and do a search, i know of at least 2 guys running nitrous.

 

tried keep coming up with stuff thatreally doesnt lead me to anything. with 100 more horse and less heat from the turbos i would think it should be quicker. maybe not though. still alot cheaper and since you only use it everyonce in awhile it would be less general wear and tear on the car

 

ive setup wet systems on many cars just never on a twin turbo car. i was going to go with an adjustable regulator so i give it a bit more fuel pressure. a colder smaller gapped copper plug and spray it right at the throttle body.
