Electronic Ignition

[Of_Machines]

I'm planning to fit my Firenza with an electronic ignition, though unsure of where to look for a suitable one or what particular type i'd need, what would be peoples suggestions?

OHV or OHC?

Here's my 2 pence worth:

I fitted a Sparkrite electronic ignition to my '67 Viva, and a Tandy electronic ignition to my '72 OHC Firenza. Each was constructed from a kit of components. They used the existing contact breaker. I replaced the ignition coils with standard 12V coils, and bypassed the resistor cable.

Some electronic ignition systems replace the contact breaker with a magnetic or (optical) pickup unit. IMHO the advantage of using the contact breaker is that you can quickly and easily revert to standard coil ignition if anything goes wrong. However, they both worked perfectly for years - and I've still got them, somewhere.

The above systems contained a transistorised generator that applied a high voltage to the coil, supposedly creating a more efficient spark. Cheaper systems were no more than a power transistor acting as a low voltage switch, which prevented sparking across the contact breaker points and eliminated erosion of the contact surfaces. You get this benefit anyway with the high voltage system, plus you get the enhanced spark.

hth,

Kits on ebay, cheap and seem to work quite well.

Hi David, thanks for the respons, my 1972 Firenza is the 1759 cc SL model so it's probably very similar to yours. So I will try to source something similar.

I've used the powerspark type electronic conversions in the last 5 cars I've had. In the HA viva the conversions done 20k miles with no problems whatsoever. For 30 quid the only thing you lose is the need to adjust and change points. There are gains in reliability, fuel consumption (as the engine stays in tune) and peace of mind. I'd wholeheartedly recommend making the change..

Thanks for the advice guys, i've purchased one of the reccomended kits!

Thanks for posting this as it was a question I intended on asking.
I wonder if they have a bulk discount

[flexbuttcheck1]

if you put electonic ignition in do you remove the ballast resistor and can you run a normal coil like a lucas?
