123/GB-4-R-V-IE for 4 cylinder Lucas distributor (with trigger impulse)

The 123/GB-4-R-V-IE distributor replaces most Lucas-distributors for 4 cylinder engines

The unit offers 16 different advance-curves, which can be selected by means of a small switch. This is a great feature to easily fine-tune your engine!

Features of the 123ignition 123/GB-4-R-V-IE

The "V-IE" model replaces distributors with a Bosch D-jetronic injection system (a D-jetronic has 2 extra contact points for controlling the injection). (please compare dimensions before ordering)

- Vacuum-advance
- Automatic dwell
- Automatic power-cut after 1 second
- Gear shift retard

Please note the following about the 123/GB

We strongly advise you to check the dimensions of the 123/GB with the original distributor.

The 123/GB-4-R-V-IE is a 123ignition that has vacuum advance. If you don't need this, you can order the 123/GB-4-R (WITHOUT vacuum advance).

Please read the installation manual carefully. It contains more information about static timing and the advance-curves, the specifications of the 123ignition and a step-by-step description of the installation procedure.

Coils and spark plugs

Although used coils all look alike, they should be viewed with suspicion since one cannot tell from the outside whether, and how often they were exposed to overheating in the past. Installing the 123ignition system will ensure that the coil will never overheat again in the future. We recommend the 123 Blue Coil.

Perhaps you'll also need new spark plugs? At 123ignitionshop we have recently added the spark plugs most commonly used in addition to the 123ignitions we offer. See: the spark plugs list.
