As we've push the limits of Nissan's VR38 V-6 twin turbo engine we've been able to uncover some of its weak points. As part of our journey we found in big bore, stroker and high RPM engines, the oil pressure would drop at higher revolutions. After a lot of research and experimentation, we found that the air inside the motor would become turbulent enough to introduce bubbles into the oil. At higher RPMs, the bubbles would even reach the oil pump pickup. With the oil pump ingesting air, the oil pressure would plummet which could cause engine bearing damage over time. We tried many things to try to shield the oil from the turbulent air but eventually found that a deeper oil pan took care of the issue.
