Macster

0.5mm is 0.019". That's some wear.

My vague recollection is at least one noted engine builder is not in favor of grinding down the Boxster crank rod (or main) journals to fit oversize bearings, even if they are available. He was also not in favor of building the worn rod (or main) journals up either by welding or hard chroming so factory bearings could be used.

Still relying upon my vague memory, but I seem to recall he seeks out used engines from which he can possibly obtain a good crank.

So there's that and I have to admit I have not tried to stay current regarding any advancement s made in rebuilding/resurrecting the 986 Boxster engine.

But a search turned up a company that apparently does offer oversized rod (and main) bearings. Here's a link:

What the steps are to get the crank journals properly sized and probably hardened/heat treated so the crank has the same (nearly the same) strength as before with the proper journal hardening and finish and size/clearance I have no idea. But at least if this is done oversized bearings appear to be available.
