I'm using American-made Integral Cams, Stage 2. The supposed best were "Twiggy Cams", but production was very limited. Integral makes THE most aggressive cams for the FS, but only a fool would try to use the Stage 2.5 or Stage 3 in a street motor.
My car made about 151 whp before we dialled it back to 148 whp (with cam gears) to get some low end torque back. In the 151 whp trim, it was pretty useless since it made less power than stock below 5000 rpm. Stock on this same dyno is around 113 whp for the supposedly 142 bhp variant of the FS-DE.
I don't know what the Corksport cams are, but if they're the same as the FS-ZE cams, they're not very useful. Good for a 5 hp bump, maybe, so not worth the money. The Integrals were good for a whopping 15 hp difference.
If you're into eco-modding, forget them... my fuel economy went down the drain with these cams. I'm still trying to source a set of FP-DE cams from the 1.8 to see if they fit... will be a fascinating experiment...
