S114-780 is a Hitachi starter reference used across Nissan RB20, RB25 and RB26 engine applications. Exact-number application records specify 12V and approximately 1.2kW, but replacement listings cover several pinion-tooth variants; tooth count is therefore not asserted. This page remains Probable/noindex. Confirm the complete label, pinion teeth and diameter, flange, terminals, transmission arrangement and vehicle model before ordering.
Send the machine model, engine model or nameplate photo so our team can confirm compatibility before shipment.
