I found a guy that is selling his mazdaspeed cams that have about 4000 miles on them and was wondering if these will make a difference in a MSP or if they are the same cams that we already have.
they are an improvement, but they are not turbo specific so you wil not get the gains you might expect. on the n/a car i think . hey give about 5-10whp more. do a search there has been plenty of talk about them lately.
