Mitsubishi EVO 4-9, 4G63 System with Air/Oil Separator

This dry sump system was developed to solve two major oiling issues that plague the Mitsubishi 4G63 engine platform, oil pump cavitation at high RPMs and massive blow by in the crankcase, as well as deaerate the foamy oil before it heads back to the oil tank. Using Dailey Engineerings signature series billet oil pan and 3-stage, or optional 4-stage, dry sump pump with air/oil separator, this system can be configured to meet the oil flow demand of any 4G63 configuration and will maintain constant oil pressure throughout the entire RPM range. This system will effectively evacuate the crankcase of the blowby gasses that leak past the piston rings, creating negative crankcase pressure, and increasing performance.
