Intake and Exhaust Cams!!!

forced induction does not neccisaruliy like longer duration cam profile
higher lift yes
longer duration will sometimes cause excessive valve overlap wich is the opposite of what you want in forced induction
now again maybe those particular cams are degreed for minimal overlap. i dont know
 
very true! in the past i have done a lot of work with turbo honda motors. from testing the b18 we had found that it makes more power running the stock cams then cut ones. some people also have been getting good #'s running turbo on type r cams in a b18. but hey thats honda. were talking MAZDA's. i personally have a "p5". it will be boosted with in 3 weeks with a slightly modified spool kit. i am new to the fs-de motor. so with some reasearch, i have read and heard the the 2.0l likes the j-spec intake cam and the mazdaspeed exhaust cam with a turbo application. i maybe wrong. they say that the #'s aren't that much greater, but cleaner power band. but i see it as more the merrier! i will just have to wait till the dyno to get some real #'s
