I'm not sure what I'd gain with forged pistons unless I change
the crankshaft and put a Danielson head, no? I'm sure the
head will bust before the piston. I think the ideal would
be to build in parallel another engine, over a year or two, do it
right, and I'll have more experience with the turbo by then, and
swap them etc...
What I think I will do is remove all the pistons, not just the one
that is damaged, inspect them with a micrometer, compare to
specs, put new rings, put everything back. I'll change all seals
and gaskets in the process, and might as well put new headbolts.
Like I said the head has been replaced once already, maybe more
than that in term of retorque, so there is probaly fatigue on these
bolts.
