i got a kent cam in my 2.0 8v, and its ok, you get a kick about 3,500 rpm, and pulls really well, it is alot faster, however the ax power is at 4,500rpm which is very disapointing to be honest, hav had it on the rollers, had the cam timing adj and it just wont give anymore!
But as Mk2GTI2.016v said, you get what you pay for really!
