Hey there! This is my first post and I apologize if this is posted in the wrong area or if it has been asked before, but I have a little issue with my ride. I drive a 1984 rx7 5speed gs with a 12a rotary. I Don't know a whole lot about cars, especially rotaries, but when I hit the has and get to about 3000 rpms my car makes a god awful screeching noise, it makes it whe, I have it in neutral and when I'm driving, also it only makes it sometimes, not constant it happens about 50% of the time. I raised my alternator, there's a new belt on there, and I'm going crazy. Any help? Thank you guys
