hell ya!!! they are but try to find them ! the people the have that car don't know what they got and the other that mod the car keep there stuff !!! the only thing the mazda will sell you is the mani and the turbo but you got to be part of some stupid racer program !!!

i do know that the company that make the injectors for the wrx make the injectors for the protege .. and that the wrx injectors fit and work i am going the buy the hard ware parts that mod the mazda speed like the better mani intercooler and that stuff .. but the injectoers and the feul mangement is what im having problems with not much out there and the mazdaspeed has bigger injector then what the car would ever use for that turbo
