The pistons in question are a custom CR, so they dont stock them. you seem to know all the answers......hehe

Have their been any reports of CP pistons breaking squirters?
As far as measuring the clearance I was thinking that you could make a feeler gauge from a length of thin metal rod. Bend it at on end then gring/file it down until its at .080" and use it as your feeler gauge.
Could you shim the squirters up abit to add clearance?

If you look, even at the stock piston, the clearance to the oil squirter is minscule. It is really a poor design by the OEM, so have even a stock piston coming that close to the squirter.
There is no reason to shim the squirter, becuae all of the new Arias pistons clear them just fine.

[QUOTE=gq_626]Yes, CP Pistons also had the clearance issue. ZNitro(IIRC) was one person that built his motor up in his home garage, and his machine shop encountered the same issue of pistons hitting the squirter.
No, I found the problem with the CP pistons.. all my machinist did was the boring of the block, I did the clearence work myself. I have many years of engine building experience in my home garage,if you want it done right do it yourself.
I went back and fourth with CP and in the end I had to do it right, I think they have it worked out now.

My memory is terrible. 
So you actualyl noticed the clearance issue yourself? What did you do to solve it? Did CP fix the pistons? Or did you fix them yourself.

You are good machinist. From talking to you on the phone, I know you really know this engine inside and out.
PS: The total bill...we discussed...was just a tad higher than the initial estimate. $1500, which included tearing down the complete engine, and reassemble the complete engine.

one of the more significant advantages of piston oil squirters is cooling of the piston... pretty much all factory turbo engines come with them and as of the last 15 years or so most performance engines in general, at least the ones i have researched, include them. I think the advantages of piston temperature reduction are pretty obvious to us all... but in short you are going to further stabilize the combustion chamber and reduce piston expansion... to not have them would, i assume, increase likliness of detonation or preignition, increase the probability of piston over-expansion related damages should the engine be run hard enough to build up a concentration of heat there.... etc etc... not to mention its kind of a waste of oil pressure to be spraying a broken one in some random direction possibily contributing to windage losses... but i guess in the end im more of an assembler guy, i dont do blueprinting, machining work, etc... so i could only guess. i do know that if i personall broke one off in one of mine or a customers engines, i would most certainly get right on that.
in other words.... IBTL.

As you probably realize (which is why I presume you went with Wiseco), even though Wiseco pistons are not as popular in the VQ community as Arias pistons, they are nonetheless very good. I spent hours and hours researching whatever information I could get on the different piston manufacturers and, when it was time to build, I also went with Wiseco.
A few years ago there was a report on ImportBuilders.com that compared Wiseco pistons to CP, JE, Arias and Ross pistons. That report was very favorable to Wiseco pistons, but no longer seems to be available. The website now links to BluePrint Racing, who only seems to carry Wiseco pistons. One could take the view that they only carry Wisecos because they like them the best, or that they wrote the report to show the Wisecos in a good light since they are a Wiseco dealer.
It's hard to say without having the actual report in hand. I called BluePrint Racing asking for a copy of the report and requesting permission to post in this forum. If I hear back from them, I'll post whatever I get.

Wiseco pistons were the custom-spec'ed GTM ones and they look almost identical to their GTM spec Arias pistons too. I like how they were cheaper as well.
Someone else will break before these pistons at 500-550whp.

Only thing I could think to make such a difference would be in the manufacturing tolerances of the piston or the rod. I have Carrillo rods and feel very comfortable that they would be very consistent in their dimensions not sure about Eagles
