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.

D4R83

D4R83 is a great Hitachi distributor, used on 1980s Nissans and Hondas. The austin boys swap them into A-series engines too.

Subaru uses same part code as Nissan (22100 for distributor) as stamped on the distributor body.

Isuzu D4R uses a different case hold-down

This looks like D4R electronic distributor. It was found in Australia:

This has the one-piece ignitor & pickup (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.
