Spencer Posted February 23, 2010 Share Posted February 23, 2010 May not be the compression problem but I wouldnt be happy with the rocking pistons. Modern jap pistons are most likely hypereutectic and they run a reasonably tight clearence, shouldn't be enough to move them noticably Quote Link to comment Share on other sites More sharing options...
KKtrips Posted February 23, 2010 Share Posted February 23, 2010 Could be some sweet forgies - being as they are good for boost and the guy building it may have been clever.... Quote Link to comment Share on other sites More sharing options...
Spencer Posted February 23, 2010 Share Posted February 23, 2010 If they are forgies yes ignore that, still measure it. Forgies run a bigger clearence but it still shouldnt be a massive movement Quote Link to comment Share on other sites More sharing options...
