Hi,
Which Ignition Coil do I need to go with a Metro Electronic Ignition?

Thanks

I think it mainly depends on whether your setup is balasted or not.

Woah, there is no ballast wire fitted to this system it uses a coil of 1.5ohms (not less) supplied with full battery voltage.

Use without a ballast resistor

Most mk2 metros has the lucas electronic dizzy and a balast wire

Gcl143 is the correct item. There is no ballast.

That's the old unipart number, I still use this for cross reference

The GCL143 is 0.9 Ohms, AC mentions 1.5 Ohm. The Metro Distributor is a 65D IIRC.

Yes that's correct, I run a GCL143 in all my minis as they're all A+

Use GCL143 as a part number for cross reference, that's the number I use on Ebay etc.

Incorrect MK2 metros with 998 engines used a ballast system. The MK2 metros fitted with the 65dm4 dizzy (1275 engined cars) used the same 1.5 ohm coil and no ballast circuit.

You can tell when wired wrong, you get a part throttle misfire below 2500rpm. The original coil is 1.5ohm, modern replacements are 0.9ohm and will not perform as well. Try a proper 1.5ogm unit and you feel the difference in part throttle torque.

So any of the Viper Dry Sport Ballast 1.5 Ohm, but without the additional ballast wire.

I can't say I've ever seen anything other than a GCL143 equivalent with factory electronic ignition. That's with a "black box" amplifier module whether separate or screwed to the side of a type 65 dizzy.

 

I've also no reason to doubt AC saying he used 1.5ohm coils, but I am puzzled how one with greater impedance would work better. The opposite is true if you mismatch ballasted & unballasted coils. The 3 ohms in the ignition circuit appears to be there to keep the points from melting and the electronic system does away with those.
