The Beast I Drive Posted June 9, 2009 Share Posted June 9, 2009 Hey ya'll, I have a pair of what appear to be JDM flat top EA71 pistons new in the box that I got from Honduras, they are stamped with a 25 on the piston top, and the box says .25 on it. They are factory Subaru parts, Im assuming the numbers mean they are .25 mm oversize? If anyone can confirm or deny this that would be a great help. I also have USDM pistons new in box that have 50 stamped on them. If anyone has another pair of flat tops with 25 stamped on them for EA71, let me know, we can work out a deal. Also, I have a full set of standard size EA71 piston rings, will these work on the pistons if they are .25 mm oversize? Thanks! -Bill Link to comment Share on other sites More sharing options...
backwoodsboy Posted June 9, 2009 Share Posted June 9, 2009 The rings will need to match the pistons. 25 over was the largest oversize subaru offered IIRC. Link to comment Share on other sites More sharing options...
The Beast I Drive Posted June 10, 2009 Author Share Posted June 10, 2009 Hmm, well the USDM pistons say 50 on them... Ill take some pics, this is the stuff I got from Loyal 2.7 Turbo a little while back.
