I've got a 1994 WRX engine (EJ20G) I'm going to have rebuilt and one of the items to be replaced is the piston rings. However the piston rings I see on Ebay are for 2002-2005 cars for example this: http://cgi.ebay.com/ebaymotors/02-05...item2eb269e663

Any ideas whether these will fit on the 1994 OEM pistons or alternatively a source where I can get piston rings that should fit these pistons?

 

Got the answer. Part number is 12033AA730 and only works for 1993-1998 WRX & STI so the 2002 rings won't work.
