This is an upgrade for that 20+year old factory cam angle sensor.
 
It replaces the factory system with a 24 minus 1 disc with a Bosch VR reluctor sensor. It's a complete bolt and plugin system and can be fitted and back up and running in as little as 15mins making it a perfect upgrade for anything from 150kw RB20DET to a 600kw RB32 without the expense of a full aftermarket crank trigger kit It can stay with you as you change engines as the same kit works for any of the RB twin-cam engines. It works with Stock, HKS, Tomei, and Greddy cam gears.
Works with: MaxxECU, Link, Haltech Elite/platinum sport, emtron, motec
