basically trailing is stock 1 coil to control it threw the dizzy.
then each leading plug has its own coil. the spark plug wire goes from the coil right to the plug.

on my na 12a 1980 sa, i cant stall the car out now. what i mean is if i drop the clutch in first at a dead stop the car will buck once and pull forward. my car idles slightly under 1000 rpm. you get a much stronger spark on the leading plugs since each has its own coil.they only problem i can see with this setup is cause the leading now is a wasted spark setup. ie both plugs fire at the same time.i dont know enough about 20b's to know if that would cause a problem with the 3 rotor setup. if jeff20b shows up he can explain it alot better.

Gmonsen, from the other forum, is using the RX8 rotors in his 20B N/A. They thought he was having a problem with the rotors and side seals but it turned out it was something else. Logan at Defined Autoworks is building my 20B N/A and he says that there is no real advantage....to much possible downside for to little upside.

yeah... that's kind of what I read from Carlos Lopez.

I'm definitely going to go at this point with S5 high comp rotors.

Now I'm going back and forth about going with EFI or carb. If I could get a carb set up pretty cheap, I might just do carb.. If EFI, I know I could go NA now and go FI later and use the EFI.. Hmm.. decisions..

i think you have this backwards. leadings fire at the same time and can be off of one coil and the trailings fire individualy.
