XDI vs 12 plug dizzy
 

Looking into options for 12 plug and am contemplating both a 12 plug dizzy (JB, BURNS) or the electromotive XDI... The XDI is the cheaper option, but what are the other benefits?

If you are considering EFI at some point, you could do a Megasquirt I or II kit with twin EDIS controllers/coil packs. It would certainly be less than a new dizzy, might even be able to do it for around $500 if you can DIY most of it. The EDIS stuff is robust, cheap, and easy to find in the u-pick yards.

Bragging rights :D

When I built my SC engine into a 3.3SS, I used the XDI ignition system. My main reason for going this route vs a 12 cylinder dizzy was ongoing maintenance costs. With this system, I don't have to worry about having to buy an expensive distributor cap/rotor in the future. The system was easy to install (just follow the very complete instructions) and worked the first time the engine was fired. I wanted to use a modified CIS system so room was an issue. I finally decided to make a bracket that mounts on the little shelf between the engine and the engine compartment firewall. I added two relays on the left side electrical panel and mounted the control unit inside the car behind the passenger seat. If I was to do it over again, I would buy the complete system that is provisioned for both ignition and fuel just in case I ever want to change out the CIS (which runs quite well). As it is, I would most likely just convert to PMO carbs and keep the inplace ignition system. Good luck with your project!

I had planned to run EFI on the car when I started building her, but changed plans recently. My initial thought was to use a system from PE-ltd.com (sponsored my last rally car) and build intakes using triumph 46mm throttle bodies. After some time I decided that carbs was a simple and much less time consuming endeavor.
