I'm trying to figure out what brand of piston I have. I bought a car with aftermarket pistons in it. I dropped the oil pan and I don't see any brand thats stamped onto the bottom. But it has the # 22147 stamped on the bottom.

 

Well gee,let me get my catalogs from every possible piston manufactuer and take a look for you.

How about a clue as to just what motor your talkin about there?B,H,D,K,F?????????

 

B series GSR

I called JE, wiseco, arias and they said its either not theirs or they stamp the bottom of the piston.

 

well sounds like they jipped you buddy lol question how do you see the piston from the BOTTOM of the block especially if all you did was drop the oil pan?

Have you ever seen a motor being built or apart or even pics?

 

i didnt know i had to be so specific...

I dropped the oil pan, removed the oil pick up, the oil splash shield. And then I used a light to shine up from the bottom of the motor.

hmm... forged aftermarket piston and rods vs stock cast iron piston and rods.
Yeah you right I got jipped.

These people on here and so stupid to changed to forged components.

lol

 

Did you ever find out what pistons they are i just got the same part# mystery piston

 

Dude this thread is 8 years old! What the ****

 

You never know if im the only one with this mystery piston and the only thing thats even closely related is this dead end thread figured id try

 

If you pull the head there might be a number stamped on top...which is where most manufacturers put their serial/part numbers from my experience.

 

The pistons are out and there is no marks on top or the inside of the pistons just the part #

 

Just Trying to figure out what brand to order wrist pins

 

Anyone?

 

That looks like a job number for a custom piston. Call each major piston manufacturer and ask them if that number fits their numbering system, they will be able to give you specifics for that piston.

 

Check with cp

 

I got curious and did a bit of googling. They don't match the design of any SRP, JE, CP, Wiseco, or Aria's piston (or any other that I found) except one.

Ctrl+F for honda (around page 115) Looks like those are a set of older Manley Pistons.

The groove between rings 1 and 2, and the notch at 45 degrees for the wrist pin clip gave it away to me. Also the shape of the pin boss area

 

I looked up almost every major one and it states they must be marked on the bottom even if its a custom spec

 

How did you get to that i open up the link on my phone and it is only a 30 page catalog?

 

Look at the page numbers pn the actual page...

 

I guess technically it's on page 20. I was looking at the actual page numbers printed on the pages haha

 

I looked at it and the piston does look very similar but why would they change their part numbers if its the same spec piston

 

I don't think it's a part number. It's probably a job number.
