Enter Z1 Motorsportsand Jim Wolf Technology. We will be taking that statement as a challenge and will be building this engine with help of some of the best Nissan minds in the industry. To top it off, Nissan says these parts are not serviceable. Because of the lack of an intake camshaft, this engine cannot be modified in the conventional sense when it comes to controlling the valvetrain. This makes the continuous adjustment of the amount of the valve’s lift and duration of opening relative to the crankshaft’s rotation during the intake valve event in the four-stroke cycle possible. The movement of the output cam is varied by rotating a control shaft with a DC stepper motor that changes the fulcrum of the links that move the followers. The VVEL system does not use a camshaft, but instead uses complex combination of parts including a rocker arm and reciprocating followers that open the intake valves by transferring the rotational movement of an eccentric cam to an output shaft. This is due to its VVEL continual variable cam timing system on the intake side of the engine that can infinitely adjust both the intake valve lift and duration. The Nissan VQ37VHR is a notoriously difficult engine to modify in naturally aspirated form.
