I would give 200% of my budget for this project for a fancy CDI system like you have Peter... (can I get one for $400?)

Other than that, I have personally replaced a MSD CDI system (6AL) with LS2 coils with a significant reduction in misfires and power increase of about 15 Hp (400ish horsepower N/A V8).

Strangely, I too found the CDI to misfire significantly more at idle (as TTT found).

All I want is enough ignition energy to light the air/fuel charge in my Naturally Aspirated Rotary until the VE decreases to the point that I might as well stop. I am expecting this to be between 9,000 and 10,000 RPM. I am reasonably confident that 120mJ of ignition energy will get the job done.

If every car was a Ferrari, I would be walking to work.

I just want something that is functional and inexpensive.

The LS2 coils appear to fit the bill.

I hope they do, because I have installed them on the car and will hopefully be starting it this weekend.

MSD is not know as MY SPARK DISAPPEARED in our game without good reason

The right products even in that brand can work

You will see Rod Millen Toyota Tacoma fitted with a MSD dis2 HO, it only makes 1000bhp from 2lt though it will be part of the stuff I will copy and post up.

I need to go play some Elvis songs now "In the Ghetto"

Another type of ign I have been trialing from Japan is ULTRA CDI's, Mazda factory use them on most PP set up's they are working well.

CDI really is the best, though I suppose some type of inductive could be made to work, but I doubt it will ever be on par.

If you have access to a scope I'd like to see how much current, secondary kV, and burn time, you get on your system.

Erm, I'm not sure how you a running LS2 coils with a CDI box as the Ls2 coils have there own built in Ignitors. I thought that this type of coil would be a total miss match on a CDI system?

Sorry Guys, scratch that last post, I misread what was written.

I didn't realize that the MSD was "replaced" with LS2 coils..
