- 2002.5 Mazdaspeed Protege5
Hi, I have a 02 Protege5 with 129,2XX miles on it. I have basic mods done to the motor. Megan Racing Catback, INSYS/Ebay short ram intake, and Manzo(M2 Performance) headers. I've been wanting to get a RWD vehicle for a while now and decided that i am not going to get one anytime soon. So the main point is, is the FS-DE really worth boosting with almost 130k miles on it? If im going to be keeping the car for a while, I might as well get the most out of it as I can and make it an even more fun car. Would boosting decrease the engine life if I run at around 6 or 7 psi?
