Hi, just my experience..
I have used both Jun 3 and Toda C on my B18C with ported B16A heads.
Jun 3 - Low to mid-range not fantastic. My vtec crossover point is at 4800rpm. After vtec switch over, the cam will suddenly pull real hard from about 6000rpm all the way to 9000rpm. Throttle respond from 6k to 9k rpm are awesome. I think if set properly on a B16 engine it will pull all the way to 9.5k to 10k no problem, coz on my B18C, the dyno graph showed that peak power was like at 8950rpm, and it was not dropping yet but lift throttle off at 9100rpm already. Idling also a bit problem but still not too rough on slow speed.
Toda C - Compared with Jun 3, it had better low to mid range power, i think due to the higher duration on the smaller lobe. I found it more difficult to set the cams and the idling was a bitch.. difficult to drive daily on street use.. At vtec cross over point, the power delivery is much smoother and it still pulls comfortably to 9k rpms. But it lacked the sudden surge like the Jun 3 at 6k to 9k.
For outright top end power, I feel Jun3 is better than Toda C. But Low to mid rev i feel toda C better.
Now i'm trying to source other cams option from Japan and USA. Looking for cams to test for daily street use that will give more power than the CTR cams yet near stock idle and another set of cams for outright top end power.. Will keep you guys updated when i get whole of a set to test..
