The Hitachi D4R electronic distributors are used by the early E-series engines. These can these be modified to work in A-series engines. See E15 Electronic Distributor Swap for details.

Overview

These have an inboard transistor ignition unit, compared to earlier 1978-1982 A-series USA distributors with the outboard "matchbox" ignition.

Hitachi D4R series Electronic Ignition distributors are used by E-series Datsun/Nissan, such as the E15 Pulsar. This can be modified for use in a Datsun 1200. It has a much-improved advance bearing plate, which was the bane of the 1974-1982 D4A points distributor, as well D4F and D4K EI distributors. This new D4R type uses a screw-on cap and improved rotor.

E-series shares basic distributor features with A/J/E/L distributor (shaft diameter & length) but uses an L-series style tang drive instead of A-series gear drive. The hold-downs vary, otherwise the cast body is the same.

Stator has only two poles (compared to the previous "teethed" stator with 4 poles) but the magnet appears to be stronger.

This has the one-piece ignitor & pickup (ignitor part number Nissan 22020-15M00/22020-15M20)

Advance Bearing Plate

It has a simplified design compared to the earlier D4 distributors. The plastic bearing race contains 4 ball-bearings (up from 3) and slightly beefier design.

The bottom race is similar to the older Hitachi, but slightly smaller.
