Frank B Posted September 19, 2004 Share Posted September 19, 2004 Has anyone here had success with swapping the EA82 maniold on the EA81 engine?? I remembered discussion about the swap as I was replacing the manifold gaskets on my hatch today. Link to comment Share on other sites More sharing options...
bratsrus1 Posted September 19, 2004 Share Posted September 19, 2004 Hi Frank This is Jerry, yes i have a EA82 intake on my hatchbrat and it has a EA81 engine in it. If i remember the top hose is the stock EA82 and the bottom is the stock EA81 hose. Thanks Jerry Link to comment Share on other sites More sharing options...

spanky_pete Posted September 19, 2004 Share Posted September 19, 2004 Did you guys see any significant gains after swapping the manifolds? I'm willing to try anything if I can get a little extra power out of my ea81. Link to comment Share on other sites More sharing options...
TomRhere Posted September 19, 2004 Share Posted September 19, 2004 In the process of doing that now on the '84. Cotton picking snapped off intake bolts anyways!! Hope to finish it today, as I don't have to go into work for a change. Only one broken bolt left to deal with, and it's coming out of there, one way or another. What I've found in doing test fit, Had to remove the little nipple for the hose on the EA-82 manifold at the T-stat housing. Note to self; you still need to plug that hole. Did cut off the boss that was there and un-needed, was in the way. Had to bend down the bracket that holds the one heater pipe on the engine, the one that runs to the waterpump. Tube for the vac-advance on the disty is real close to the T-stat housing, still musing over what to do there. Blocking off all of the emissions stuff, and removing whatever else I feel like removing. Going thru all of this 'cause I have a Weber sitting here for the EA-82, and it don't fit the EA-81. This BRAT better like the Weber after I do all of this work. I know the '82 liked it, but it had the EA-82 engine in it also...... Link to comment Share on other sites More sharing options...

Frank B Posted November 9, 2006 Author Share Posted November 9, 2006 Bump for an update...... Does anyone have pics of the areas modified? Wasn't there some discussion about mounting the intake manifold backwards to avoid these problems? Link to comment Share on other sites More sharing options...
ecky Posted November 10, 2006 Share Posted November 10, 2006 Sorry, no pics, but a friend and I did this to his 81 wagon. had to modify the t-stat housing, but it worked great ecpecally with the wire tied secondarys on the ea82 carb. Link to comment Share on other sites More sharing options...
GoldDiggerRoo Posted November 10, 2006 Share Posted November 10, 2006 My question is could you do put an spfi setup on a late EA81 hatch with the feedback carb..... it's already got an ecu....same connections? Just swap intake, engine wiring, and ecu? Moms hatch needs something done to it......that thing is miserable, such a nice car otherwise. Link to comment Share on other sites More sharing options...

hancho3 Posted February 16, 2009 Share Posted February 16, 2009 Im in the middle of a ea82 manifold w/ weber swap to an ea81, now with the carb sitting on top with it all bolted together it seems that the choke is in the way of the distributor. anybody know of any way aroud this? I think i read something about putting the carb on backwards and flipping the throttle bracket upside down, but if I do that it hits the manifold. Maybe a carb spacer will do? Here are some pics: http://picasaweb.google.com/KurtAbersold/Subaru?feat=directlink thanks, -Kurt 81 Brat GL Link to comment Share on other sites More sharing options...
