2jz timing belt tensioner upgrade#

The OEM timing belt tensioner brackets are prone to cracking and breakage in high RPM/high HP applications. Powerhouse Racing Billet Timing Tension Bracket This gear also features a more precise and square tooth shape so trigger edges are even better defined. When comparing the 36-2 tooth gear to the 12 tooth version, the 36-2 tooth gear offers better crank shaft position resolution for more precise ignition and fuel injection timing.

This is a common upgrade for cars with aftermarket ECU's. This timing gear features lightening holes on both the front and rear of the gear to keep it as light as possible, and the steel material makes for a less brittle piece so teeth are not easily broken. The Powerhouse Racing One Piece Billet Timing Belt Drive Gear for the VVT-i 2JZ-GTE features a one-piece design and is CNC machined from billet steel. PHR One Piece Billet Timing Belt Drive Gear for 2JZ-GTE (36-2 tooth pickup wheel) Some racers choose 36-2 for more resolution on their timing signal even on a non vvti setup. It also has more defined edges which can provide a cleaner signal. However, the teeth on the vvti version are brittle and do commonly break so we have devloped a billet version (see below). Meaning you may not need to change the gear on a VVT-i setup. It is a single piece and does not suffer from the same potential seperation issues. **NOTE FOR VVTi*** A 2JZ utilizing the VVTi system has a different timing gear with 36-2 tooth setup. Rather than welding the factory gear, PHR has made the move to CNC a single-piece steel timing gear to offer an even stronger product. As a solution, we have built a one-piece gear to so that you can never have to face this issue. This will cause running and timing problem. One common issue is the timing pickup will often separate from the main timing belt gear and spin causing a trigger/sync error. The torque specification is 28lb/ft and be sure to retain the factory washer that's sandwiched between the oil pump and your billet tensioner bracket.Powerhouse Racing has always been on the top of the world in creating solutions to common problems that occur with the 2jz engine. You will also want to apply some common grease to the shank of the bolt which holds the tensioner to the oil pump and a dot of blue Loctite on the threads of the bolt to keep oil from seeping out of the engine, as its retaining hole is through-hole. If the valve tip were to break off it can damage the combustion chamber, piston and other various components as well.ĭuring installation, the lock washer on the idler pulley will be deleted and we recommend a drop of red Loctite in its place. If the bolt or belt break during operation, the majority of aftermarket camshafts will cause the pistons to hit the valves, bending or breaking them and requiring a cylinder head overhaul. Once this happens the timing belt itself can fail, or the bolt can fail as the movement of the engine can cause the bolt to break. While there are many well constructed aftermarket unbushed steel tensioners on the market, when used for a long service interval - as you would find on a street car or road race vehicle, over time the lubricant used during installation will be displaced and the bolt can fuse to the tensioner.

They will continuously wear and eventually they will interfere, bind, and seize. Galling is wear caused by adhesion between sliding surfaces. The bronze bushing is of paramount importance due to the susceptibility of like-material galling. All tool paths in our tensioner have the longest possible radii to make the part as strong as possible while still fitting in the OEM location. It is constructed out of 6061 Aluminum and utilizes an oil impregnated bronze bushing, as well as a steel insert for the factory hydraulic belt tensioner to ride on.
