Building the Nissan VQ37VHR part 2

On the bottom, the windage tray is the next part to go on.

We had to grind the windage tray slightly to clear the ARP studs.

Next the JWT oil pump pick up extension is installed.

The JWT oil pan extra capacity spacer is installed with the oil pan.  The engine now has an extra quart of oil.

The knock sensors are bolted down.

Next the lower intake manifold is installed.

Our engine is now ready to be installed into its 370Z!

Stay tuned, there are a lot more parts to be installed in our next segment and we will get the car up and running with a tune, and dyno time.

  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
