I have a 1988 Rx-7 with a original 13b street ported motor. It has turbo 2 transmission, drive shaft, and rearend. It is making a clicking noise from the rear when im in a straight line and when I go around corners. I can't seem to figure out what it is. Can anyone help?

 

Hey guys should I put a s/c or turbo on my street ported rx-7...which will be cost efficiant
