Custom JE pistons. They are a much more current design bridge style piston with much shorter wrist pins. I sent them a mold of my combustion chambers and no knocking at start-up, so they got them right out of the box. They set them up for stock pistons rings, so I just swapped them over, no break in.
Note that the valve reliefs are by valve, not one big relief like with the SJBMW pistons below. Note: I thought the Venolia Circlips were hard to get in. They turned out to seem easy after I had to put the JE Circlips in, really hate them. Now I welcome the Veniolia ones.
JE pistons again, you can see a little of the low friction coating for the piston skirts.
Here's a gambit of different wrist pins - top view. Trick Ti pins on top (note diamond coat color difference); middle pin is the original JE steel pin; bottom pin is the SJBMW Venolia pins.
Gambit of wrist pins again - end view. Left to right, Venolia pin; original JE steel pin; Trick Ti pin with Aluminum inserts to make them the same length as the original JEs (2.050" long). Note; the end thicknesses appear much different but thickness at the small end of the rod isn't. The Venolia is very tapered from the end in, the JEs have no taper and the Trick Ti do not either. All the IDs at the small end are within a 1/32" of each other. The Trick Ti is easily the lightest of the bunch, with the JE next, then Venolia with the stock pin (not shown) feeling like a brick in comparison.
