Pooparu Posted July 13, 2006 Share Posted July 13, 2006 I recently purchased a pair of heads from XSNRG for my 1990 Loyale Turbo, and on the driver's side exhaust port there's a threaded hole that wasn't on my original heads. What is this hole for? (O2 Sensor...) Link to comment Share on other sites More sharing options...

mrroot Posted July 13, 2006 Share Posted July 13, 2006 That'd be for the Exhaust Gas Recovery (EGR) pipe.. I'm not quite sure why your old heads did not have this - a 1990 model engine would certainly have EGR - this an older engine? Or maybe someone swapped the heads before using an older engine? Also - you might try posting in the other forum "Newer Generation of Subarus" as they're for 1990 and up cars. We're old farts in here.

PoorManzImpreza Posted July 13, 2006 Share Posted July 13, 2006 He's posting in the right section..some ea82T didn't have EGR and his 90 Loyale turbo is one of them.. Link to comment Share on other sites More sharing options...
idosubaru Posted July 13, 2006 Share Posted July 13, 2006 like they said, EGR. you'll have to block that hole off, but the head is perfectly useable on your motor. you might try posting in the other forum "Newer Generation of Subarus" as they're for 1990 and up cars. not true. Loyale and other vehicles are included in the "Older Generation Forum" beyond 1990 because they have the older generation EA and ER series motors in them. New Generation forum is for EJ models. The Older Gen forum says Before 1990 Unless Loyale, XT6 etc...for this reason. Link to comment Share on other sites More sharing options...

Pooparu Posted July 14, 2006 Author Share Posted July 14, 2006 Thanks, very helpful. I'll just plug it up and move on. Link to comment Share on other sites More sharing options...
calebz Posted July 14, 2006 Share Posted July 14, 2006 Yup, I went through the same thing. I am going to guess that your old motor if from a CA car (or your car is a CA car). That was my experience with my 88 Turbowagon. No EGR. Link to comment Share on other sites More sharing options...
Caboobaroo Posted July 14, 2006 Share Posted July 14, 2006 I got me a nice pipe plug for mine since my intake is off of a '88 XT which was naturally aspirated so no EGR! Link to comment Share on other sites More sharing options...
