Re: '09 TSX/'12 Civic Si 11:1 87mm piston/ringset. $399 shpd in cont.48

Honda has changed Si part numbers 3 times since they came out and prices as well, a 2012 SI piston has a different number than a 2013 SI, Honda has updated the piston. They are all basically the same, skirt coatings are a bit different. Another reason is a different manufacturer.
ahhh. so would the most current ones be the better then?

2009-2014 TSX
2013-2014 ILX
2013 SI
all use the same pistons now

2012 Si is the only oddball.
which is the only ones I maybe wouldnt use since they had oil consumption issues.

I know this is an old thread but I am just seeing it now and wanted to give some feedback. I've had these pistons paired with TSX rods in my K24a1 block with Kelford drop in cams and the Supertech flatface valves for several years now so far so good. From what I remember my builder/tuner, Derek Robinson, never went the full 50* he maxed at 45*. Not sure if that was for tuning or clearence but take it for what you will. This car is also my daily driver and have put on about 30k since the swap.

Where can I find the casting for piston set A or B?
I have 05 K24A2 Block.
If you're looking at the engine from the front it's on the left hand corner of the block up front, depending on what you all have attached to the engine it may b a little hard to see
