The King main bearings were installed in the bed plate.
Next a bead of sealant was laid out on the bed plate.
We lubed up our freshly balanced, polished and WPC treated crank.
We also applied assembly lube and installed the crank thrust bearings.
The bed plate was put into position. The the ARP studs and ground hardened washers were lubricated with ARP’s assembly lube.
The main studs were carefully brought up to the proper torque in 3 steps in a cross pattern.

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.
Basically the pump capacity is ok, the problem is the gears break at high RPM.
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.
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.
It is pretty close to the VR. With tuning the VVEL system can give you a bunch of power.
What are the benefits from using the larger valves from a titan truck ? Was there any modifications done to make them fit ?
more flow. The seats must be cut for the larger valve.
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
