I found the result of the pin runout - 3 out of 6 pistons (assembled on the conrods) are a little sticky in their movement, the other 3 move freely yet without play.
This will be my 4th engine in two years (original blew, replaced by importer at no cost, that one blew, rebuilt it, and now rebuilding it again). With the detail going into this one though, and everything I've learned from this board over the past two years, I feel that the chances of this engine lasting a good long while are high - it wasn't the high powered tune I was running (the pistons and head are immaculate), it was the absolute shite bearing fitment that eventually led to bigger and bigger problems.
The new crank should help alleviate any crank thrust play (along with correctly fitted bearings) as well as adjusting the clutch pressure. The shop has promised free thrust checks every six months - that's pulling the oil pan and visually inspecting the center main bearing. Sounds good to me!
On the parts front, I decided to add an HKS Racing blow off valve - the basic SSQV has problems holding 2 bars of boost - it leaks at that pressure. The Racing version is good for 3 bars so they say.
