One of these billet tensioner paddles might be a worthy investment since you're going to all that trouble:
FOR PORSCHE: 10610, 106 10 - READY TO SHIP - (BILLET CRANKSHAFT TO IMS CHAIN TENSIONER PADDLE BOXSTER/CAYMAN)
It takes OEM Porsche tensioner pads.
I saw a 3.6 from a 03 C4S that was in my mechanic's shop for a rebuild the other day and the tensioner paddle was snapped clean in half..
