I did not know and am very surprised the 993TT, or your 993TT is single plug/single coil because all the normally aspirated 993 engines I've seen are twin plug with dual distributors and 2 coils like the twin plug 964 used.

The 964 turbo was CIS through while the 993 twin turbo finally got rid of the miserable CIS and went digital with way more accurate crankfire triggered motronic, and MSD 6 series CDI boxes do not work with motronic from everything I've read.
