FORGED H-BEAM CONROD KIT SR18DE/SR20DE(T) by Tomei

TOMEI Connecting Rods Usually, to give con rods strength and maintain lightweight characteristics, an H-beam or I-beam profile is applied. The choice of the profile is dependent on its purpose, use environment, production cost and quantity. TOMEI applies H-beam profiles for the connecting rod of Nissan RB , SR , CA , VG engine and have succeeded in gaining high buckling strength while reducing the con rod weight. TOMEI Connecting Rods are forged from molds with the main bearing hole predetermined, not machined from a solid piece. This produces a connecting rod with supreme durability which can withstand extreme conditions. Lack of the large ends strength leads the metal to distort and the bearing to wear out. To secure enough strength, TOMEI applies ‘round shoulder shape at the link of the rods large end. To provide lubrication to the bushing in small end, instead of sending oil through the long hole inside the rod from the large end, TOMEI assembled a tapered oil hole at the top of the small end so that the oil will drip during the pistons compressing cycle. This way the strength of the rod wont be sacrificed. NISSAN Year Model SubModel Cylinders Liter Aspiration Eng Desg.
