mattyboy1989 Posted April 12, 2010 Share Posted April 12, 2010 hi just wondering could you use tt pistons in an na-t to lower the compresion what would the side effects be ? would it be more reliable? and anything else lol? Quote Link to comment Share on other sites More sharing options...
Kirk Posted April 12, 2010 Share Posted April 12, 2010 The only way CR should be lowered on any NA-T build is through the piston.It wont bring it down to TT CR level but should land you around the 9:0:1 region which is a good medium to build on.Thicker HGs are not the way to lower CR! Have a read through this thread to understand why http://www.mkivsupra.net/vbb/showthread.php?t=209281 Quote Link to comment Share on other sites More sharing options...
