4wheeldrivefun Posted June 19, 2009 Share Posted June 19, 2009 hello, So I have a 1994 pathfinder 4x4. I pulled compression and im showing 40 in cylinder 4 and 60 in cylinder 6. So I put some oil into the cylinders and it shot compressions up (this tells me its rings). So I am about to remove my engine and rebiuld it at 217k miles. Unless i can find a full longblock or shortblock. The cylinders look really washed down (lack of cross hatching). However looks like i maybe going the rebiuld route. Dose anyone make aftermarket pistons? or longer rods? or anything cool for the bottem end? Link to comment Share on other sites More sharing options...
MY1PATH Posted June 19, 2009 Share Posted June 19, 2009 Loads of parts available thanks to the 300zx. Yes on differant pistons, weisco and other brands. Eagle among many other brands makes a ligter stiffer rods but they are all same length. Make sure you order for the correct wrist pin; there are 20mm and 22mm variations. Finish it of with Deves Racing Rings. If you get the 300zx pistons make sure your compression ratio stays @ 9:1 the turbo Z's were 8.5:1. Link to comment Share on other sites More sharing options...

Nytrosfinder Posted June 19, 2009 Share Posted June 19, 2009 Weisco pistons would be a safe way to go... reliable and the make a great product!
