Also, I've heard from many that the C cams make your car barely streetable. I assume they mean the car is very jerky and runs pretty rough. So unless your car is just for the track/strip, they're not recommended, at least for now.

*NOT* true! There are actually 4 different 'flavors' of the C-series cams available. C1's, which have the shortest duration, idle somewhere between S3's and S4's and make lots of yummy torque and give about a 15 hp peak power gain over stock '91 cams (more on later cars--for the record, S3's give about 9 peak hp over stock). C1's should prove to be very very good on built turbo cars.
C2 intake/C2 exhaust combo made 22 peak hp more than the stock cams. The cams idle very well, about like S4's. I even passed CA's stringent rolling dyno smog test with these cams.
C3 intake/C2 exhaust cam combo made 26 peak hp more than stock cams. Idle is a little rougher than S4's. Not too bad, but it is very lumpy and there is some surging/bucking around 1000 RPM or so.
C3 intake/C3 exhaust combo made 33 peak hp more than stock cams. Idle is rough. It is solid, and the car doesn't stall. However, it can be *very* rough and choppy, especially when the car is cold. Sub-3000 RPM throttle response is quite poor. Only manly men should run these cams (sissy G-20 and B-14 owners need not apply

. I still wouldn't call them 'unstreetable', though. At least they aren't really any less streetable than my 350 lb/in springs ;-). If I had to drive my car every day, and I had to pick one set of cams, I would still take the C3/C3 combo. But then again, I went to the University of Michigan, so I know how to deal with pain and suffering
All of the hp numbers that I quoted are the gain in *PEAK* hp. They are not indicative of the maximum amount of power gained at any one RPM. In fact, the C3/C3 combo netted me 50 wheel bp at 7500 RPM over the stock cams. When you plot the C3/C3 dyno curve over the stock cams, you will see the incredible gain in area under the curve. I can simply annihilate stock-cammed SE-R's on the road course. I can easily out-power Type R's on the straights.
If the C3/C3 combo is too hard core, the C2/C2 combo is very very streetable is feels about as fast (even though it clearly is not).
