300ZX Z32: Boost Jets

[dickie]

The ECU doesn't do much without the boost jets. This is where the horsepower comes from. They're about the same size & shape as a .22 caliber hollow point bullet. Except they have a 1 or 1.25mm hole through them



The jets fit in the end of the wastegate vacuum hoses. These attach to the fittings on the bottom side of each intake pipe before the rubber intake hose that feeds each throttle body. To do the driver side,



grab the squeeze clamp



with a pair of pliers & move it down the hose, then pull the hose free from the pipe. Insert the boost jet 'nose' first into the hose.



When reseating the hose, they get pushed further in. Be VERY careful not to drop them down into the engine compartment. The passenger side



is a little more difficult. Remove the rubber intake hose feeding the throttlebody



to get to the fitting on the intake pipe. Loosen the hose clamps & slide it off. Stick a shop rag in the intercooler tubing to keep anything from falling in. Repeat the procedure from the driver side.



Then reattach the intake hose.
