my friend just bought a CrainCam hi-6 fireball for his RX7 and he said it is great and totally worth the money. I know that MSD is cheaper (around 170 compare to 228 for my friends). Has anybody used either of the product and tell me which is better?

 

i like the msd units... i have used both but i like msd better as a personal type thing... they are both good ignition systems for our cars... you can get an msd 6 6al or sci with a blaster coil and have a stout system... if you want a rev limiter go with the 6al or the sci... if you have built your motor for very high revs then get the sci or step up to a 7al... a lot more money involved in the 7 systems but well worth the money if it is going to see race duty...
