How To: Install An EFI Nitrous Kit
Bottle-Feed Your Mustang And Beat Them With Some "Giggle Gas"
Everyone wants to go faster (myself included), but the first comment always made is, "but I'm on a budget." Well, of course, we all are to some extent. It takes a responsible person to keep from yanking out his credit card and buying every part he needs until the card is maxed out. The budget problem is inevitable for all of us. But we still want our performance, right? Of course we do. That's why dollar for dollar, a nitrous oxide kit adds more performance than any other single enhancement you can put on your Mustang. Most EFI Mustang nitrous kits are in the $500-$700 range for the basic setup.
But why does nitrous oxide possess the stigma that it is unsafe or difficult to tune for performance? Well, as with any story, there is a bit of lore and wives' tales that have become expanded and wilder as the years pass by. The truth is that in today's high-tech world, nitrous oxide is just as safe and easy to install (if not easier) than most any other performance enhancement. By following the kit's detailed instructions and not going outside the realm of the kit (for instance, trying to run 250hp jets in a 150hp system), nitrous oxide is a safe, inexpensive, and proven way to add horsepower and torque to your Mustang.
Several years ago, we installed a Nitrous Works adjustable EFI kit on one of our resident 5.0 Mustangs. The kit worked well but required a separate fuel pressure regulator that had to be adjusted whenever jet changes to the nitrous system were made. Nitrous Works has refined the kit by extending prebent hard lines from the solenoids to the freeze-free spray bar plate, so you don't have to find room to mount the solenoids on your cramped inner fenders. The fuel pressure regulator is no longer needed, as they have tweaked the jet sizes to work with the stock EFI fuel pressures. All in all, the system is much easier to install and less of a hassle to use. Today we install this refined adjustable nitrous kit (50-175hp levels) on a '93 5.0.
