Detailed Product Overview

WAI DST1024 is engineered as a complete ignition distributor for direct replacement service on select Nissan models. The aluminum housing supports durable construction, while the optical distributor design is built for consistent ignition signal control. Because the cap and rotor are included, this unit is prepared for installation without sourcing separate top-end distributor components. This part cross-references Nissan 22100-40F00 for the same application.

Compatible With 1995-1996 Nissan Pickup, N/A; 1990-1994 Nissan D21, N/A; and 1989-1990 Nissan 240SX, N/A with Hitachi distributor ID 22100-40F00. The DST1024 is a strong fit for buyers searching for a Nissan Pickup distributor, Nissan D21 distributor, or 240SX distributor replacement by part number.

Common Issues This Part Can Address

• Hard starting caused by a worn distributor assembly
• Misfire or rough running from inconsistent ignition signal output
• Distributor cap and rotor wear affecting spark delivery
• Ignition timing instability related to aging internal distributor components
• Failure of the original distributor housing or optical mechanism

Installation Notes and Tips

Verify the existing distributor ID before ordering, especially on 1989-1990 Nissan 240SX and 1990-1994 Nissan D21 applications. Confirm that the vehicle uses distributor ID 22100-40F00 and compare the connector and mounting layout to the original unit. The ignition coil is not included, so reuse or replace that component separately if needed. Always follow factory service procedures for timing and final engine verification after installation.
