My GTV6 makes a similar sound when I step on the gas. It started after I
replaced the clutch and the front tranny mounts (which raised the front of
the transmission 1/4 inch). I think it's one of the giubo's hitting the
handbrake cable when the transmission or the driveshaft moves around under
high torque, as I can feel the rattle in the parking brake lever. The
center driveshaft support needs replacing, which probably allows the
driveshaft to move more than it should.
