It depends on what you are doing.vr4retrofit wrote:which one do I want
If you are wanting to "plug and play", it's a good choice. The 2 wires go directly to the coil (just check the polarity) and away you go.
IF you are wanting to do a bit of tinkering yourself with the timing curves, the GJ onwards, Scorp dizzys with the full cap for the rotor button like this..

would be a better option.
The springs are easily accessible and easy to change their tension.
