i've got an 88 tii. when ever i'm driving at highway speeds and punch it, lets say in third or fourth gear and my boost is topped out for 3-4 seconds i hear a loud rattle noise from my foot area. it sounds like a heatshield rattling (but i have no heatshield). could that noise be caused becaused the turbo is overboosting. any ideas would really help. this is my first turbo rx-7 and i'm still learning the inns and outs of turbo. thanx
