Part #: 800-1616
New Borla big throat throttle body for Datsun 280Z and 280ZX.
This 60mm throttle body is designed to replace the original equipment units on Datsun 280Z and ZX models. Dynamometer tests have shown improvements in torque and horsepower in the mid and higher engine RPM ranges on otherwise stock engines. We do recommend minor modifications to the stock inlet manifolds to maximize the performance potential of these units. When used in conjunction with other engine modifications these "Big Throat" throttle bodies will show substantial power increases, albeit, at the expense of their intended street legal status. It may be necessary to transfer the by-pass screw and spring from the stock unit on some years. This throttle body has 2.75" O.D. inlet which will require a larger hose than stock.
Includes gasket and mounting bolts.
