Subject:Re: total seal ring end gap on 95mm pistons?

John,

I'm working on a wbx - originally out of an '87
syncro, now going (hopefully in the next couple days)
into my '84 westy.

Why 95mm P&Cs?  Ummm... slightly bigger for slightly
less?  Would i do it again?  Probably not.  I don't
have a lot of experience with this stuff, but just
looking at the castings between oem and these, oem
does seem quite a bit more refined.  But man... that
1mm of pure unadulterated HP will knock your socks
off!  People have been using them with a bit of
success, though, it seems.  Long term, they still have
yet to be proven.

Regarding your chevvy comment - to go 101.4mm pistons,
you'd have to do some major modification to the case
as the cylinders are right at 100mm stock.  I don't
think a -0.7mm cylinder wall will do much for you...
There is talk of fancy 97s on the horion, but those'll
likely cost you a pretty penny.

Hope that answers your question,
-Damon
