I have a d16a6 in my 91 si and i wanna remove the governor and be able to hit 8k rpms but... like most people id rather not blow my engine. Nothing added to it like boost or anything just an intake and straight pipe so i wouldnt really be pushing it much farther than what it can handle i think. Im just looking for ways to avoid the worst case and do some major damage. Is a must that i change the valve springs for stronger ones? should I replace the head gasket for a new one? I mean just so the older more worn head gasket doesnt blow? I mean im changing the intake gaskets anyways so why not
