Switch to a solid camshaft belt tensioner and eliminate any risk of the stock one collapsing. This will replace your OEM hydraulic tensioner and is a great idea if you are running high RPM, heavier cam springs, or just like to run the car very hard.

This will fit both the DOHC non turbo and DOHC Turbo 1991-1999 3000GT and 1991-1996 DOHC and Turbo Stealths. It may also fit other 6G72 applications, but please verify before ordering.

An optional on adjustable tensioner pulley will prevent that component from slipping out of adjustment as well, fairly common on high RPM engines.

Pictured is the optional non adjustable tensioner pulley (can’t slip) and optional #8 upgraded bolt for the pulley.

*This will not automatically adjust overtime and its a good idea to periodically (every oil change) check the cam belt tension, although it shouldn’t need much if any adjustment in the lifespan of a timing belt as timing belts are fiberglass re-inforced and stretch very little over time.

We had some requests for knowing what the torque on the tensioner bolt is with the tightness we are running it. Its very hard to measure, you will need a 1/4″ drive beam torque wrench, but we are getting about 10-12 in. lbs.

This is with the Gates Racing Belt, an OEM belt may need more tensioning torque to achieve the same amount of belt deflection..

We have also attached a video of how we set ours. This is most likely a little tighter than OEM.


The shown tension is only a guideline and in the end the customer/installer is responsible for their own belt tension. It should be checked again after rotating the engine twice, just like the service manual recommends.

You will also want to notch the lower timing cover to provide service access to the adjustment bold and lock nut.

We have been experimenting with using tuner apps on your cell phone and are finding tension to be in the region of 85 hz when strumming the longest span.
