GeneralDisorder Posted September 24, 2011 Share Posted September 24, 2011 Depends on the EJ in question. The EJ257 (USDM WRX STi) is a bit larger than the 93 Impreza EJ18. But not as much as you might think. GD Link to comment Share on other sites More sharing options...

GeneralDisorder Posted September 24, 2011 Share Posted September 24, 2011 2.5 = for the ej22t 91-94 turbo ej Funny thing is - the EJ257 uses the EXACT same headers, cross-over, and up-pipe as the 22T. GD Link to comment Share on other sites More sharing options...
