| Z1 Upgraded Z32 throttle body set for 1990-1995 300ZX 
Brand new direct bolt on Throttle Bodies designed specifically for the Z32.
These are new throttle body castings complete with butterflies, shafts, and stops designed to fit directly on to a Z32 upper plenum and utilize all the stock linkage, hardware, and TPS with no modification.
Benefits include:
*35% more cross-sectional area than the than stock units.
*58mm diameter butterfly vs 50mm diameter stock butterfly
*Improved throttle response
* Dyno tests show power gains throughout the power band, gains increase with power output.
*Direct bolt on application (simply grind out inside of upper intake plenum to match larger opening)
*Great fitment with standard 2.5" I.D. coupler or hoses
*Pressure tested to 40 psi
*Coolant passages on bottom side have been eliminated
* EGR and PRVR ports still in place (can simply be capped if these systems are no longer in place)
Forget the Stanza and 240sx throttle bodies that require many hours of cutting, welding, and fabrication to fit the Z32. These throttle bodies were designed to fit the bolt pattern of the stock Z32 upper plenum. Just simply grind out the inside of the upper plenum to match the size of the Z1 Throttle bodies and bolt on. All the springs, spacers, stops, and TPS are a direct fit onto the shafts of the Z1 Throttle bodies.
These new upgraded throttle body sets made specifically for the the Z32 are not available anywhere other than Z1 Motorsports.

Comes with (2) new throttle body -> plenum gaskets sized to fit properly. EGR and PRVR vaccuum ports come with caps over the ports.
Stock intake hoses will not fit over these throttle bodies, you must use an aftermarket hose or coupler with a larger ID. Z1 Motorsports is producing larger chrome intake hardpipe kits for NA and TT Z32 models to connect and supply air to the upgraded throttle bodies. Coming soon!
