Will this ignition conversion kit improve S3 performance?

I’m working on upgrading my S3 reliability and performance. Does anyone have experience with this conversion kit from Barrett?


I have this left over. $100
I’m not sure how it compares to other upgrades.
The E Type is not listed, but I’m pretty sure the early XJS’s had the same Opus system.
Hopefully someone will chime in.


The sIII already has an electronic ignition. When mine failed, I just got an aftermarket one, same difference, but much lower cost.

I’m suspicious of people who don’t like dogs.
But I trust dogs who don’t like people.
