Can someone fill me on the details ? Is this a bolt on or do they need modification etc...

Yes they need machining to fit the shaft into the origional hole

Does someone over there offer them done ? Any pics or anything. In the post I read it mentioned a controller for the advance curve, they are a full electronic set up ? Any links would be good.

Thanks

Try doing a search on magna on this forum - the details have been posted before, but below are some bits I cut and pasted for you.

To fit a Magna dizzy, you disassemble the internal shaft and withdraw the internals.
On a lathe slim the external shaft down to the same size as a 009 (were talking thous). The leg on the Magna dizzy is longer so you can cut it to the same length as a 009. Then machine a groove in the leg for the oil ring of a 009. Cut the internal shaft to the correct length, drill the shaft for the pin that locates the bottom half moons and there you have it! Perfect, but you need access to a lathe!

The later model EFI dizzy has twin hall effect sensors. So it can be used as I did for sequential fuel injection, one pickup fires the cyclinders the other locates TDC, the dizzy has twin chopper wheels, 4 on the external wheel and 1 on the internal.

It fits a type 1 motor easy, but on a Kombi you need to clearance the tinware with some heat and a hammer. It's tight but it fits.

The early 4 cyclinder magna dizzy could be used for fuel injection also, but on something that only does fuel like an F9 Haltec. (F for fuel only in Haltecs lingo). The fuel would be controlled by the computer and the spark by the Magna dizzy.

NOTE – Early 4 cyl Magna distributors are vacuum advance, single hall effect trigger (no points) – so will not work with Kadrons unless the body is drilled to generate a vacuum signal takeoff.

Adrian,
I used a '86 Magna dizzy. Had it cut down and added a new oiling hole to the side of it. Did not have to shave the outer as it was a neat fit. (I have a picture of the completed job which I will post later). I bought the Jaycar Programmable ignition kit as well as the Jaycar High Energy Ignition kit (They are designed to work together) worked out to about $200 including dizzy, machining, electronic kits.
If I get the time this weekend I will measure up all the changes to the dizzy and post here.
