Nissan Timing Wheels
The first cut of replacement timing disks has been done, and is documented VehicleFitment/Nissan/SimpleTrigger
In an attempt to 'normalise' the various Japanese trigger wheels to the 24 pulse (12 pulses per crank revolution) and 'n' sync (0.5, 1, 2...) - as used by Toyota, Honda, Mazda RX7. A candidate for the S13, S14, S15, also Z32, and later engined Skylines has been drawn.
It will also be possible to get triggers for the GTiR SR20, S12 CA18 and KA, which have much larger diameter trigger wheels.
History and Detailed Information
Having looked at the Nissan Silvia and 200SX models (S12, S13 and S14) they all use a cam driven timing wheel with a speed sensor of 2degree resolution and portals of different sizes to denote the current cylinder.
