Nissan Pulsar GTiR Engine To Transmission Locating Dowel (Upper) SR20

The Nissan Pulsar GTi-R Engine to Transmission Locating Dowel for SR20 engines is a precision-engineered component essential for maintaining drivetrain alignment and reliability. This solid steel dowel, also referred to as a transmission locating dowel or block-to-gearbox pin, is positioned on the rear face of the SR20 cylinder block, typically in the upper machined hole near the transmission bell housing. Measuring approximately 20mm long by 10mm in diameter, it is pressed into the block to protrude slightly, ensuring precise alignment between the engine and transmission during installation. Accurate alignment is critical for preventing issues such as input shaft misplacement, clutch or flywheel interference, and gasket leaks at the joint. This dowel ensures proper torque transfer and maintains the integrity of the drivetrain, making it indispensable for performance applications. It is commonly inspected or replaced during engine rebuilds, transmission swaps, or performance modificati
