Next the crank thrust clearance was verified.
Next the rest of the bed plate bolts were tightened down.
Our pistons were verified for proper assembly direction. JWT spec JE pistons have an offset pin to reduce noise so this is critical.
The pistons were installed on the K1 rods.
Next the King rod bearings were installed on the caps and the rod body.
The rings were spun in place and the gaps were staggered.

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
