Building the Nissan VQ37VHR part 2

The oil pump and a new water pump are installed.

Next the timing chain is installed with attention paid to all of the timing marks.

The chain dampers are installed next.

Then the chain tensioner is installed, then the pin is pulled out of the tensioner to apply tension to the chain.

Our cam drive is now installed. The engine is rotated around to verify that the timing marks are all correctly lined up.

Next we install a degree wheel and pointer on the crank to dial in our cam. A few things like decking the block and head can affect cam timing and we degree every cam install we do to make sure everything is right. There is a lot of power that can be lost if the cam timing is off by just a few degrees.


  1. Replacing with upgraded oil gear only is sufficient versus full upgrade of oil pump assembly and cover? Always pondered the value in doing so or maybe there’s a horsepower threshold so any insight is appreciated.

      1. Kojima-san, thank you for sharing your insight so I decided to purchase the full assembly including the billet cover from Boundary. I also opted for their MartenWear for convenience since they also offer this service although there are other things I may reach out to you separately regarding WPC. Stay well.

  2. Other than the bizaro heads the block looks similar to the VR38 and drag racers are pushing around 1100hp out of the stock block, 1700hp with sleeves, and up to 3000 on a billet block.

    The VELL is trick but it locks you out of a lot of otherwise simple modifications.

  3. What are the benefits from using the larger valves from a titan truck ? Was there any modifications done to make them fit ?

  4. Hi,
    In the build you used the Titan valve is sodium filled for better cooling and is 1 mm larger for better flow. As the VQ35HR is similar will the same valves fit as was done on the VQ37VHR if so what is the OEM part number so that I can purchase them.
    Thanks for your many articles on Nissans
