How to Tell 1g Pistons from 2g Pistons

[Tanro]

I just got my pistons in the mail. I highly suspect of these. For 1 it was supposed to be 2g pistons on 1g rods and unless these have been used I doubt it cause they are dirty as shit and don't look as though they have been machined. They appear to have the same dish as the pistons that where in the car. I will try and find the camera and get a picture later.

measure the wrist pin

What is the diameter of the 2g Wrist pin vs 1g Wrist Pin?

 

[BogusSVO]

the Ig is smaller, the 2g is a 22mm I want to say

 

[Tanro]

Confirmed I did get 2g Pistons. Excellent.

now you do know you have to have the small end of the rod enlarged on the 1g rods to fit the 2g wrist pin..
