Powerhouse Racing has always been on the top of the world in creating solutions to common problems that occur with the 2jz engine. One common issue is the timing pickup will often separate from the main timing belt gear and spin independently of the timing gear, causing a trigger/sync error. This will cause running and timing problem. As a solution, they have built a one-piece gear to so that you would never have to face this issue.
Rather than welding the factory gear (which typically ends up messy), PHR has made the move to CNC a single-piece steel timing gear to offer an even stronger product. Zinc plated to prevent corrosion.
**NOTE FOR VVTi*** A 2JZ utilizing the VVTi system has a different timing gear with 36-2 tooth setup. It is a single piece and does not suffer from the same potential seperation issues. Meaning you may not need to change the gear on a VVT-i setup. However, the teeth on the VVTi version are brittle and do commonly break, so they have developed a billet version. It also has more defined edges which can provide a cleaner signal.
Some racers choose 36-2 for more resolution on their timing signal even on a non vvti setup. If youre running a standalone ECU, we strongly recommend swapping over to the VVTi's 36-2 tooth gear for the same price and getting a better read/signal for your computer!
