setting 3 chain cam timing

[Jamesp]

I bought the car after an IMS failure at 120K miles. The IMS was taken out with the bearing
(common), but the rest of the internals are undamaged except or wear, so the path forward is replace anything worn along with a new IMS bearing and shaft and stick it back together again. A very cost effective way to buy a boxster if you have the technical information to re-assemble it, which brings me back to setting the camshaft timing. Do you know how to set it? There is plenty of information on the 5 chain, but not so much on the 3 chain engines.
