These jets are the determining factors concerning the power production of the nitrous system. The jets are sized by orifice diameter and we elected to go with the smallest jet-.38
Next up was the funny fog. After a proper cooling down period, the XS Engineering Dynojet was once again brought to life. On the bottle, the Maxima generated 220.1 hp. The graph seemed a bit choppy and we surmised that a fresh set of plugs would smooth the graph and maybe add a pony or two. We were hoping for more power from the kit and KG's Kurt Gordon was quick to point to the fuel pump, not the kit, as the likely culprit. In Kurt's experience, Nissan fuel pumps max out at 60 psi, while others, like Hondas, flow willingly to 80 psi and beyond. We contemplated adding a Kenne Bell Boost-A-Pump, but logistics and scheduling kept us from venturing down that road.

When mounting the nitrous bottle, be it in the trunk or within the car, it is wise to face the valve of the bottle toward the front of the car.
On the road, the Maxima felt like it had a gust of extra wind in its sails when the nitrous system was activated. While not a racer by any stretch, when on the bottle, the car passed traffic briskly; the V6 proved to have an appetite for nitrous. Our next installment of Project Maxima will wrap up the series of articles, as we plan to outline some of the other, more extreme, possibilities for power hungry Maxima pilots. Stay tuned.

The key to the ZEX kit's user-friendly personality is the integrated distribution block, which computer-controls the flow of nitrous. On one side of the block there are three wires, a power wire, ground wire and the activation wire that leads to the Throttle Position Sensor (TPS)...

There is also a port for incoming nitrous that connects to the bottle...

On the other side of the block are ports labeled Intake, Regulator and Nozzle. The Regulator port is joined to the fuel pressure regulator to ensure a bump in pressure when the system comes online. The Intake port ensures that, in case of a spike, any excess pressure is bled off and routed into the intake system so when the throttle plate is closed fuel pressure returns to stock levels. The Nozzle port flows the nitrous to the engine.
