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 modifications to guarantee reliable operation.
This dowel functions identically for both rear-wheel drive and all-wheel drive SR20 variants, including the AWD SR20DET in the Pulsar GTi-R and the RWD SR20DET in the 180SX or Silvia. Its location and purpose remain consistent across both transverse and longitudinal engine layouts, ensuring universal fitment within the SR20 family. Choosing genuine Nissan components from Terra Firma Automotive ensures precise fitment, durability, and the high performance expected from your Pulsar GTi-R.
