Hi guys, I'm in the process of fitting a metro turbo engine to my mini and, of course, I have some problems.

The engine looks like a mk1 metro turbo, with the 59dm4 dizzy with separate ignition module (which is missing, of course). I found the ignition module, should be an equivalent to the LUCAS DAB201, but I'm bit stuck as I can't find the wiring diagram of Dizzy/module/coil, would any of you be able to help me out.
I searched almost everywhere on here and on google without any luck.
Thanks in advance
Massi

Thanks mate, really appreciate that.
Still not sure how to wire the ignition module though as I don’t have the original connector.
The module has 6 pins, and I have only 2 wires going to the dizzy and 2 to the coil 🤔

What module have you purchased?

 

There are many modules which will work. Inside the AB14 is just a 4 pin GM HEI module. Basically any module for an inductive trigger distributor will work. A Bosch BIM024 is a common one. As well as the factory module, any that look like either of these will work and are likely cheaper.

I can make you a diagram for the factory 6 pin module if you need. I have one complete with the original wiring.

 

The two wires from the distributor will work reversed however the timing will be out of phase with the rotor, it will still run at idle.

That’s brilliant thank you, I bought a hüco 13 8001 that is supposed to be an equivalent of the Lucas DAB201.

Rotor arm and cap are missing too, I suppose that standard 45D/59D ones would work (not the blue ones), am I correct?

Thank for your help

Pin 1 - coil negative
Pin 2 - earth
Pin 3 - earth
Pin 4 - 12v (ignition)
Pin 5 - G+
Pin 6 - W-
Pin 7 - not connected.

This picture is of the plug on the module side, not the one on the distributor. If you get these two mixed up it will run but won't rev properlyAttached File  20240430_190909~2.jpg   21.87K   1 downloads

Since this is a high energy system it is best to run a nice thick positive wire to the coil from the fuse box. At a minimum you need to bypass the ballast resistor. The module itself only needs a small positive wire but there needs to be a thick one from the coil negative terminal to the module.

Standard rotors and caps will work however you won't be able to reliably open up the plug gap much. 35 thou will be fine, this system is capable of much larger but not with the standard rotor or cap. The blue components were fitted as the standard ones couldn't handle the high firing voltage of a wider plug gap that this system can allow. They also had a plastic shield that protected the pickup from the high voltage. Other manufacturers of HEI ignition systems used larger caps to prevent issues.

Just a comment on these Dizzys. The drive “crown” does break up over time and RPM. They can still be bought though. 
I got mine from H&H Ignition Solutions

 

anyway. Some pics.
