2G Wrist Pin Wall Thickness

[SpiderGST]

I am wondering how to measure the Piston Wrist Pin Wall Thickness. My engine builder is not wanting thinner than a 200 wrist pin wall. If you know so I can measure my Weisco 1400HD pistons for my 7bolt 2g.

You're Wiseco HD's have a .225 wall thickness. Pretty beefy and enough to satisfy your engine builder. That's one of two reasons they are "hd". The other is the forging process I believe.

You measure the wall thickness by sticking one end of a micrometer in the center hole and the other end on the outside of the pin. It's as easy as it sounds, you just measure how thick the wall is.

Alright thanks for the info. I will talk to my engine builder some more tomorrow.
