WTB Merc 2.5 Light weight stuffed wrist pins

[sanman116]

Looking for ultra lightweight 2.5 liter wrist pins that are fully closed not just on one side.

What is out there?

I have a set (cant remember who welded them up) but they are amazing to look at! I decided to run Wizzard pistons when I rebuilt my motor so I didn't use them.........I will try to find a pic.

Stuffed pins? Hmm first I’ve heard of this. Any measurable gains from welding them closed? Or is this more of a leave no stone unturned at every corner it all adds up a hp here a hp there approach?

Probably more of a leave no stone approach. But, I cant not do it.

If you run capped at both end be sure your rods have oil holes at the wrist pin or you will have cooling issues

Awesome information!

It’s got me rethinking what stuffed means that’s for sure. Who first thought this little trick up?
