zep Posted January 26, 2007 Share Posted January 26, 2007 Right, after a few dilemas and stuff, I decided to rip the pistons out of my block so I could replace the rods with some the right length. These are the pistons which came out of the block, they are 85mm wide and have for following: 63J stamped in the top slight dish 62 stamped on the left of the sides J stamped on the right of the sides 'Atsugi' cast into the inside on one side, and and Nissan style logo on the other inside. Pics: Cheers guys. Quote Link to comment Share on other sites More sharing options...
Raizer Posted January 27, 2007 Share Posted January 27, 2007 according to google Atsugi are a OEM manufacturer of pistons , ABS parts, steering bits and other stuff for many Japanese car makers, so there possibly just your factory pistons or an O/S replacment Quote Link to comment Share on other sites More sharing options...
zep Posted January 27, 2007 Author Share Posted January 27, 2007 Yeah, I have my doubts tho, I asked this on the Gemini forums and I'm sure someone would know if they were an o/s replacement. + I don't recall any oversize pistons being avaliavle with dish.

J2Racing Posted March 2, 2007 Share Posted March 2, 2007 They may not be a gemni piston maybe the block has been bored to suit them. Doing just that to my capri. Using falcon a three hundy a set half the cost of capri. Quote Link to comment Share on other sites More sharing options...
zep Posted March 2, 2007 Author Share Posted March 2, 2007 Turns out they were most probably SR20 pistons. Bore is 86mm. Dosen't matter now, getting a new set anyway, forgies here I come Quote Link to comment Share on other sites More sharing options...
J2Racing Posted March 3, 2007 Share Posted March 3, 2007 Thats always the best way to go. Find a piston the right diameter and right pin height. Quote Link to comment Share on other sites More sharing options...
zep Posted March 3, 2007 Author Share Posted March 3, 2007 They are coming from a shop called GemRacing in Melbourne. Forgies floating on shotpeened rods, all set to the right compression for use with the stroker crank. Quote Link to comment Share on other sites More sharing options...
