The VQ35DE (and Rev-Up) is becoming more and more available and here at 5523 Motorsports, we are responding. Arguably, one of the greatest V6 power plants ever produced in mass quantities, we have the right solution for you.
We initially identified cooling issues in these early engines when subjected to moderate to high levels of boost. We have since taken the steps to remedy this problem in our engine packages. Using late model torque to yield fasteners and upgraded head gaskets, we have eliminated head gasket failures related to inadequate gasket design. Cooling system modifications that remove water bypass and heater core piping are for track only vehicles.
Factory Nissan crankshafts are know for being very strong and require nothing more than tear dropping the oiling holes and precision balancing to make them race ready. We also use factory tri-metal bearings with your choice of coatings throughout our engine packages.
Choices of camshafts ranging from a mild street profile to a road race profile are available. All our engines come with uprated valve springs to further control valve train harmonics and valve motion.
We are currently developing race ready wet-sump oil pump upgrades to remedy the potentially problematic factory “powdered metal” oil pump gears and expect these to be in full production and available very soon.

Available for the Stage 1 engine package for an additional fee:
*** Uprated camshafts and springs available (some of these options require extensive maching work)
*** Custom cam grinds available
*** Uprated valves available upon request (we strongly recommend factory forged aluminum retainers over titanium lifters as the factory retainers are lighter)
*** Custom piston profiles avaialable
*** The Stage 1 engine package is a long block only.
*** Dry sump options available
*** Race engine development programs available. Please contact us for more info.
Available VQ35DE / Rev-Up Options:
Nismo Option Cylinder Heads - Nismo offers an optional cylinder head for the VQ35DE (DE ONLY - not for Rev-Up engines) which grafts the smaller VQ30DE combustion chamber onto the later model cylinder head. These heads are designed for NA applications as the combustion chamber is 10cc smaller. Using a genuine piston profile, the compression ratio changes from 10.2:1 to 12.0:1 - without milling the cylinder head. Couple this with availability of genuine Nissan titanium valves and you can build the ultimate NA race engine. We recommend this modification ONLY for NA race engines. Please allow ample processing time as all parts are sourced from Nismo Japan.
3.0L 73.3mm Stroke - This de-stroked option is available for early VQ35DE / VQ35 Rev-Up engines. This is recommended for primarily high RPM operations only as there is a significant decrease in low end torque. This crank with 144.2mm rods nets a rod ratio of 2:1.
Uprated chromoly oil pump gears - We all know what happens to early RB26DETT oil pumps when revved past recommended redline. Catastrophic oil pump failure is not limited to the RB engine family. We have seen multiple SR and VQ oil pump failures as a result of excessive harmonic vibration (directly related to engine speed) and are working tirelessly to remedy this dreaded problem. Check back often, as we hope to release this upgrade soon.
