Finally got around to buying the MSD Street Fire Ignition box and the tach adapter. I am trying to figure out where to mount the box and how I want to route the wires. I never realized how little space is left under the hood on the 1GS.

 

So after running my NA-T for a couple years I felt like the spark was breaking up around 4K RPM. I closed the plug gap to .026 and that helped. I decided to add an MSD ignition. I used the following parts.

MSD Street Fire 5520
MSD Tach Adapter 8910EIS
MSD Blaster Coil 8207

It runs and pulls so much better. No breaking up at any RPM.

if you do this, know that the trigger is the white wire that runs to the original coil.

I mounted the Street Fire and Tach Adapter inside the front bumper cover.

Here are some pictures.
