I think SPec B's are the way to go but I want a cam that can use a stock timing belt.
Skunk2's seem to be making very usable power for a lot less cost. AJ can better elaborate since he is using skunk2's but power per dollar the skunk2's are probably they way to go.
I would tend to agree with almost all of that, with the exception of the Spec-B breaking belts, I have still yet to see any one of the several people I know running them break a timing belt. Though if I do, you guys will be the first to know. As far as the Spec-C and Idling problems, the idle is a tad messy, but really not all that bad, if you bump up your idle a couple hundred RPMs, it's really not all that noticable.
As far as Skunk2 Stage-2 cams, they're not all that expensive, in fact almost two hundred dollars less a cam then the Todas. Not to mention they run well and make power throughout the RPM band, and not just at higher RPMs like the Toda or JUN.
If you're looking for the name more so then getting performance, the cam to get, that really makes power is the Toda Spec-C, but just remember, that you need some major compression(12:1 or higher) for those huge cams, not to mention being very careful about piston to valve clearance!!!!!!! If you're willing to forgo the name but still want the big power, look into the Skunk2 stage-3, it has very similar duration, and I think even bigger lift. When you get into cams with a lift larger then 12.3mm, you start to run into clearance issues, so be careful who you let work on your car, and later who you let tune your cam gears.
I swear by my skunk2 stage-2, they've made me very happy so far, and I really havn't heard of any problems with them from others. It's more cam then most people will ever need, and surely a good place to start.
Good luck, later!!!!
