RB30ET RB30 SOHC Crank & Cam Trigger Kit

It has been proven time and time again that Nissan engines using optical crank angle sensors mounted on the camshaft - including CA, RB, VG, SR and other platforms are prone to ignition timing drift, particularly under high load, high power and high RPM conditions. The issue can become even more pronounced following valvetrain upgrades.

This timing instability can result from a combination of factors, including timing belt stretch, belt harmonics, worn gear drives and ageing OEM distributor components. It’s an issue well known among experienced Nissan engine builders and tuners leading to loss of horsepower potential and reduced safety margin.

5-0 Ignite is proud to introduce our crank trigger kit for the RB30ET (SOHC) platform, providing exceptional crankshaft position accuracy compared with conventional camshaft only triggering systems.

We engineered this kit specifically to eliminate the compromises commonly associated with crank trigger installations. Unlike many designs, our system does not require removal of the top timing cover, leaving the timing belt fully enclosed and protected from external debris.

By retaining the factory timing belt cover, the 5-0 Ignite crank trigger system helps maintain the integrity and reliability of the timing system while delivering highly accurate crankshaft position information, exactly where it matters most: under high load, high power and high RPM conditions.

OPTION A: Full crank trigger setup. Retains your existing distributor for your home sync signal (replacement trigger discs and distributor blanking cap supplied). Can be run with stock distributor cap if you wish to retain ignition lead setup.

OPTION B: Full standalone crank and front facing cam trigger setup. Ideal for those converting to coil-on-plug configuration with neater look whilst maintaining the front timing covers.

!  DISTRIBUTOR CORE NOT INCLUDED ON OPTION A. You will need to re-use your existing distributor, swap the supplied trigger disc and distributor cover onto (10 mins job). If your optical sensor within the distributor is faulty, it is recommended to rebuild the distributor with new bearing and optical sensor (using kits such as GOSS SC001M for Hitachi type sensor or GOSS SC003 for Mitsubishi type sensor)

Our crank trigger kit features:

✔ 24 Plus 1 (24+1) trigger setup compatible with most modern standalone aftermarket ECU (NOT compatible with Nistune or PowerFC)

✔ CNC Machined Billet Aluminium 6061 Crank Sensor Mount.

✔ Genuine ZF (Cherry) hall effect sensor for crank signal.

✔ Integrated trigger teeth on supplied crank timing sprocket, compatible with OEM and most aftermarket balancer.

✔ 5-0 Ignite original unique design of tapered back crank trigger teeth for better alignment to the sensor and crank pulley clearance compared to competitors!

✔ Jacking bolt holes on the crank timing sprocket for ease of future removal.

✔ Wiring connectors supplied.

✔ All installation fasteners supplied

✔ Full Instructions Supplied (refer to 'Installation Guide' tab above). Professional Installation is Highly Recommended.

Option A cam side configuration:

✔ Clean Slate CNC machined billet aluminium 6061 replacement low profile distributor cover.

✔ Replacement stainless steel single window CAS discs for home signal (with built-in redundancy where you can use either the inner or outer optical sensor on the OEM unit). Two CAS discs supplied to suit either Mitsubishi or Hitachi sensor.

Option B cam side configuration:

✔ CNC machined billet aluminium 6061 'CAS' bracket.

✔ CNC machined billet aluminium 6061 cam sensor mount and low profile cam sensor giving ample clearance to OEM radiator fan.

✔ CNC machined billet aluminium 6061 distributor block off plate.

✔ CNC machined low profile cam trigger tooth.

✔ Retains front timing cover with small modification.

!  It is required to power up the sensors via regulated power source such as your ECU's 5V or 8V output (NOT from the ECU's 12V input from the main relay). Even though the sensors are new from factory, we bench test each sensor prior to dispatch to ensure that it is 100% in working order. The warranty does not cover damaged sensor(s) from incorrect wiring, physical damage or from not using a regulated power source to power the sensors.

Benefits includes tuner’s confidence in maximising ignition timing whilst keeping consistent engine safety margin. Suitable for RB30ET (SOHC). A MUST for all valued RB30ET builds!
