Competition Distributor
Nissan Competition sold two distributors for racing purposes. Racers have no need of vacuum advance if they drive full-throttle (at full throttle, the vacuum doesn't vary). Also extremely high RPM engines will use a fixed mechanical advance, since they run above the RPM where advance varies. Removing the advance makes the system more reliable (but less flexible).
Vacuum Advance Delete
For the standard distributor.
