You're absolutely right, the JB Racing twin plug dizzy probably would have been a superior solution. The trouble is that I already have a 964/993 dizzy, an Andial Splitter (for Montronic EMS) & the customized cables. Plus, the rebuilt 964 dizzy is a third the cost of that JB Racing unit!

If it's possible to accomplish this, I'm just trying to capture how and what it looks like in this thread.

Yes. It's a very quick 2 minute install. Porsche actually sells a ventilation kit which includes a clear rubber tube and a fitting to vent the dizzy thru the plastic shroud used to direct the air from the primary fan over the heads & cylinders.
