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
- 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.

Stock intake hoses will not fit over these throttle bodies, you must use an aftermarket hose or coupler with a larger ID. Couplers on Z1 and most aftermarket hardpipe kits or silicone throttle body hoses will fit over these throttle bodies with some lubrication and persuasion. As an option below you may now choose to add custom sized larger Z1 Silicone Intake Hoses for your Twin Turbo as an option with your Z1 Upgraded Throttle Bodies.
