Z1 300zx Upgraded Throttle Bodies

These are CNC machined throttle bodies 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(Does NOT fit with stock 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.

Set Includes:

(2) Z1 Throttle Bodies
(2) Throttle Body to Plenum Gaskets made to the correct size
(2) complete sets of new plastic throttle linkage spacers (10 pieces in all)
EGR and PRVR ports come with EPDM vacuum caps over the ports.

Also available chrome plated like shown below as an upgrade option below. It is offered as an inexpensive option that does provide a brilliant shine.
