Tomei Oversize Oil Pump
In circuit running or drag racing, lubrication trouble is one of the major reasons for the blowing an RB26DETT. The main reason for this trouble is worn out bearing metal from decreasing oil pressure, caused by insufficient amount or pressure of factory oil pump for tuned high RPM and high output engines. Also, since the factory pump gear is made of weak sintered metal, it is not rare that broken gear at high RPM damages the entire expensive engine block instantly. Tomei RB26 oversize oil pump applies an extra large pump gear that is made of high-strength material to let it breath a sufficient amount oil pressure to the tuned engine and secures strength with its original design.
