I've gone through a whole lot of BS lately trying to get my car on the road.
Despite the last shop overhoning my bottom end, and all the overspray of paint on my car from them painting their shop and all the scratches left on my car, i've run into another problem.
I bought Spoon .25 over pistons, and since they overhoned my block, I got another bottom end,(b18c-r) and wanted to know if the Spoon oversized pistons had the P73-00 stamping on the piston dome.
i know p73-00 is the JDM counterpart of p73-00a for the USDM ITR piston, but can anyone confirm that there is indeed a p73-00 on their pistons as well. Better question is, how do you tell the difference between the Spoon oversized piston and the JDM ITR oversized piston?
Before evryone starts talkin crap and saying they're the same....I don't care, I payed for Spoon pistons and want to make sure thats whats in my car. I've been through WAY TOO MUCH BS through this last shop for to have them do this to me as well.
I apologize for the snippy attitude, it's been a long summer w/out my car, and i'm REALLY upset about what this last shop has done to my car mechanically and cosmetically. This explains it all if you don't already know.Thanks for any help you guys may be able to provide.

sorry man, spoon OS piston is the same as JDM ITR OS piston

identical

no way to tell difference

only thing different is that the Spoon piston set is SUPPOSED to be balanced

 

Thats what I figured the problem would be, thanks though.

SPooN piston = jdm itr piston that is balance....NOTHING MORE NOTHING SPECIAL....why people spend almost 250 more for this is beyond me!

And better yet the balancing doesn't involve removing any material to balance them so you can't even look for that. Spoon simply groups close weighted pistons together and sells them as sets.

 

grab a digital gram scale and weigh it.

thats the only way to tell

 

Exactly what I was going to suggest.

Something accurate to 0.001g, tracable to NIST or legal for trade...

This oughta do 'er:

Just return it to the meth lab once you're done with it...
