JCviggen Posted April 2, 2008 Report Share Posted April 2, 2008 Title says it..400$ shipped to the USA. I'd make them a whole lot cheaper if the USD wasn't so horribly low at the moment. This is less than half price of new here <_< Link to comment Share on other sites More sharing options...
Keaton85 Posted April 2, 2008 Report Share Posted April 2, 2008 interested if this is what I need for my build! stock oem OS2? Link to comment Share on other sites More sharing options...
JCviggen Posted April 2, 2008 Author Report Share Posted April 2, 2008 Well it is OEM, I'm not sure which number of OS this would be. But it would appear they are OS2 as it says 81.38 on the piston and I found :"OS2 piston tolerance is about 81.33mm - 81.39mm (3.2022 to 3.2044 inches)" Link to comment Share on other sites More sharing options...
Keaton85 Posted April 2, 2008 Report Share Posted April 2, 2008 Have these been used at all?Also anyone know the HP limit on stock pistons? Link to comment Share on other sites More sharing options...
JCviggen Posted April 2, 2008 Author Report Share Posted April 2, 2008 Never used. Around 400-450 HP should be okay on them as far as I've seen. Not sure how much Doug made in the end with the yellow and GT3071R, but I know he used these. Link to comment Share on other sites More sharing options...
Keaton85 Posted April 2, 2008 Report Share Posted April 2, 2008 They just look used due to the small nick on the side, in the picture... I'm looking at around 350-400WHP for my build but im not 100% if i need to go with OS2 pistons but i guess i can always bore it out to that.
