Just changed IMS bearing at 76k in my 2002 986 S and all was good. Bearing was fine and the clutch and pressure plate could have went 100k. Installed the DOF modification from TuneRSmotorsports in Florida all went well. Installed stock bearing and now run Mobil 1 0w40 euro blend and motor purrs. Modified stock muffler with four 1/2 inch holes in tips to first chamber and drilled 5 1/2 inch holes through each secondary cat.
HAVE 800 miles on modifications and love the new sound.
