PS:
Do NOT mount the solenoids in the engine bay or the firewall. Mount them INSIDE the car near the pax side footrest - up on the INSIDE of the firewall. A few degrees warm/cold and the solenoids will start to stick. If u are unfamiliar w/ what the "hit" feels like you will stay on the button and 1) live to laugh about it if it's the nitrous soilenoid that stuck or 2) rebuild some sh.it if it's the fuel solenoid that crapped out. It's a little more labor intensive but TRUST ME - it's how you want to do it. Your fuel system can handle the 75 shot wet. If you can spring for the NOS pressure gauge, then do it.
