Nissan RB26DETT Firing Order and Cylinder Diagram
Nissan RB26DETT Firing Order and Cylinder Diagram with 1-5-3-6-2-4, physical numbering, identification cautions and routing procedure.
The RB26DETT Inline-Six firing order is 1-5-3-6-2-4. Cylinder 1 is at the timing-belt/front end, followed by cylinders 2 through 6 toward the transmission.
The RB26DETT Inline-Six firing order is 1-5-3-6-2-4. Cylinder 1 is at the timing-belt/front end, followed by cylinders 2 through 6 toward the transmission. A firing order is the sequence in which the cylinders begin their power strokes. It is not the same thing as cylinder numbering, distributor-cap clock position, or ignition-coil connector order. Confusing those references can create a no-start, violent backfire, dead cylinders, or a diagnostic trail that looks like a fuel or mechanical problem.
Use the verified order only after identifying the engine family and camshaft. Classic engines can accept camshaft swaps that change the required sequence, while modern coil-on-plug engines have no distributor cap to route. The table, bank diagram, and procedure below keep those concepts separate and show how to confirm No. 1 on compression before moving any wires.

Select each cylinder to walk through the firing order. Cylinder-bank numbering and distributor direction must match the identified engine family.

| Physical numbering | Cylinder 1 is at the timing-belt/front end, followed by cylinders 2 through 6 toward the transmission. | Orient by the timing/front end |
The firing order does not define harness pinout. Match the igniter, coil harness, ECU and cam-angle-sensor procedure to the exact chassis generation, especially when later or standalone components are installed.
Which RB26DETT Inline-Six firing order applies?
Covers the production RB26DETT mechanical order used in R32, R33 and R34 Skyline GT-R applications. This distinction matters because the engine can look nearly identical from above. Treat the camshaft or engine assembly as the authority when parts have been mixed. A firing order cast into an intake, copied from a generic decal, or remembered from another V8 is not enough to identify a modified engine.
The application table separates the order, cylinder banks, and ignition-system notes. Read all columns before routing. The first number in 1-5-3-6-2-4 is cylinder 1, but the physical No. 1 terminal can appear in different clock positions when a distributor has been installed on a different gear tooth.
