MGB - Electronic ignition

[seymourski]

I’m looking for a bit of advice and guidance on swapping to electronic ignition on my ‘74 BGT.

The engine was rebuilt before going into storage / being mothballed and a Piper fast road cam was fitted then. Since coming out of retirement I’ve (amongst many other works) replaced the exhaust with a performance manifold and free flow exhaust (from MGOC), added K&N air filters and upgraded to richer carburettor needles.

Next incoming upgrade is a Stage 2 head (finally converting to unleaded fuel!) which is due back next month to be fitted in the new year.

The only thing left on the engine side is the ignition. There seems to be a few alternatives out there and a quick search shows some concerns about the suitability of some systems but the data is a few years old.

Can anyone help steer me in the right direction and offer some good advice and suggestions?

Many thanks

Thanks Clutch. I’m erring towards the 1-2-3 and had a good chat with the tech guys at the MGOC who were very knowledgeable and helpful (and patient to explain the intricacies to a mechanical numpty like me).
I also talked to my local specialist and I’m waiting for their advice.
I didn’t realise there was so much to an ignition system!

Thanks for the recommendation and advice guys. I will stick with the tubular manifold (for now) as it’s already fitted.

Just have to decide on which ignition system.,,

Cheers

That's interesting and very helpful, also good to know there is a significant increase in BHP.

Did you opt for the programmable 1-2-3 or the version with the standard curves? The programmable version seems a bit of a faff unless there is a significant advantage.
