Thought this would fit best in tech;

I'm working on simulating the SR20 crank/con rod/piston system using MATLAB by modeling it as a simple four-bar linkage (calling out all ME's, you should know what I'm talking about). I have the dimensions from the FSM for the crank to con rod distance and con rod big end to small end distance, but to finish the dimensions out I need anyone's help who has a spare OEM piston (or installed if you really want to tear down your SR for fun!) and a good set of calipers (digital preferred).

The measurement I need is the overall height of the piston and vertical/horizontal distance from the middle of the piston pin hole to the top/side of the piston. Again, if anyone has an OEM piston laying around and calipers, let me know and we could work out the details. :bigok:

Also, post 100 very niiiiiiiice
