Welcome to the home of TDC Performance, the source of information for the 123 performance ignition system for your classic British Car!

Introducing a revolutionary new product specifically for classic Minis, MGB and many British cars: the 123 electronic distributor! The 123/Mini, 123/MG and 123/GB distributors are designed as a direct replacement for your obsolete and usually non-functional Lucas distributor and offers the advantage of having no mechanical advance mechanism, a CNC machined body and a universal high quality cap/rotor. Besides being extremely easy to install the 123 distributor offers sixteen built in advance curves that can be selected by simply changing a switch setting. 

The 123/Mini and 123/GB offer curves designed with the tuner in mind: four groups of four related curves present a logical step-wise progression that will dramatically reduce the time needed to find an optimum ignition advance curve for your particular engine formula working under your particular conditions. No distributor has ever offered so many choices in one package so you can wave goodbye to spark scatter, shaft wobble, inappropriate advance curves and impossible to find tuning parts.

The 123/MG has 16 advance curves suitable for most BMC B series engines, including all standard MGB's. The 123/GB also has 16 advance curves but both the 4 and 6 cylinder versions are designed to to replace Lucas distributors in many different British engines. If your distributor has a standard Lucas dog drive then there's a good chance one of these units will work for you. If in doubt, please contact us.
