the p29 is a fictional piston, similiar to the usdm p30/pr3. the only difference is the cast number has changed from p29 to pm7.

 

that's odd, i must have bought fictional pistons then.

no im right, but youre the man cause that is exactly what i needed to see. i am positive they are the same piston just have a different part number on the cast. they both have domes offset to the exhaust side.

on a joking note, have you ever thought of sitting the piston down and taking a picture?
here are pics i took of a pm7 out in the vegas sun, https://honda-tech.com/zerothread?id=871023

 

logistics, they are stamped P29, thus people call them "P29" pistons, they are in fact the same cast as the PM7 pistons.
i was flipping you off in that picture, with the swaintech piston as one massive middle finger

lol, ok. thanks for the pic though really, i needed to see that. i had a thread asking exactly what that pic answered.

did you take a look at the pics i posted of the pm7?

 

no problem, shame i don't have any other pictures of those, they are in the motor already.
yeah i looked at the PM7 castings, exactly the same deal.
