e series complete ignition

I'm afraid it will be very difficult to find a NOS or good complete and working Dinoplex setup for your E series Dino. Also keep in mind that the AEC103A Dinoplex is difficult to repair and forty year old electronic components are not that reliable anymore.

My recommendation would be to source a broken AEC103A Dinoplex and do a Bosch/Lumenition conversion, as documented in the thread below. If you paint the coils in satin matte black and apply replica stickers the setup will look quite original.

Any idea if the original ballast resistors will work with the new Bosch innards? Or do you need a custom-matched ballast resistor?

 

The new Bosch setup features electronic current and dwell management so you do not need a resistor. You can mount an unwired one for originality though

 

I agree with Adrian. A well restored Dinoplex is much better than an original one and visually identical. There is no point insisting on an NOS unit unless you really want the unreliability that comes with it.

 

I have a bunch of NOS AEC103A units but the rebuilt ones are the best way to go. I've heard the original units were sensitive to low voltage so it was best to keep your battery fully charged and don't use jumper cables. Better to play it safe and take the battery out and charge it up. My original unit went 47,000 miles!

 

Thanks Adrian - is that also true of the superformance units in the dinoplex case? That's what I have and it appears to use an external ballast resistor that's different from the coil mounted one

 

The Superformance unit is a copy of the mid seventies Bosch TSZ 0 227 051 021 ignition, which is basically a points and coil ignition with a transistor as load switch.
It does require an external ballast resistor, but using the original Marelli 1.5ohm ballast instead of the supplied Bosch ballast is fine.

My personal recommendation would be to replace this setup against something more powerful though, such as an MSD 6AL-2 or the high power Bosch setup discussed above.
