Breaker points replacement

[nattman]

Hi. Doing some research on replacing the breaker points on my mates Audi 100 with an electronic kit. It's a 1982 with the 2.2 5 cylinder engine. All the kits I can find are tailored for 4 6 and 8 cylinder cars, with no mention of them working for a 5 cylinder car. Anyone had any experience fitting these kits to a 5 cylinder engine?

I'd ring up AccuSpark and ask them what they can do. You never know, but a later 5 pot may be able to donate an electronic dizzy for yours but the advance curves may not be correct.

That said you have two other options besides the above:

1) 123 Ignition Dizzy Conversion

Alternatively, call up 123 ignition. They can convert your existing dizzy to become a fully electronic item but it will be at quite a cost. OTOH you would had fully mappabale ignition as well as preset curves to play with. 123s tend to be fully electronic, whereas electronic conversions only tend to convert the contact breaker element but still retain the bob weights to advance the distributor.

2)Nodiz/Megajolt ECU system for the Ignition only

The other way would be to get a Nodiz ECU, and to do away with the dizzy completely. You would need a basic wiring loom (supplied I believe) to power it up in addition to a coilpack, possibly individual coil-on-plug coilpacks or a high power coil to use your existing dizzy setup, a place to mount a crank sensor, a trigger wheel and a couple of other bits. Quite a few guys here including our very own Tepper have used them on carb conversions with success.

However this will be more work than both of the above options. However, it would deliver near hassle free reliability and do away with rotating parts and rotor arms etc. to worry about. Out of the above I reckon the 123 would be the easiest thing to setup with the points conversion coming not far behind it.

That said, if you can get Bosch points for your dizzy and you have access to a dwell meter I would stick with the points in your position. Getting a dwell meter for a 5 pot engine may be interesting however (but the feeler gauge method should work). I only recommended the dwell meter as I personally had better results from using one for setting points up .

Excellent. Thanks for that. 😀👍
