I've used this myself with great success. As well as many others in the drag racing community. ET, MPH, and HP don't lie. I wasn't able to get past 600whp without it. You could see ignition breakup on the dyno, even with the Okada coil packs. I installed this ignition, now my dyno graphs are as smooth as silk, without even a sign of ignition break up. If you run water/meth injection, it's a must.

Yes, there were some known issues with these in the past but they are bulletproof now. So long as they are wired up, mounted, and setup correctly.

 

Well then PM me everything I would need to run this setup if you would cause I will choose this over a CBR coil

 

are the cbr coils better than stock s2000 coils,is there any moding involved

 

Good luck man!
