dansvans Posted March 24, 2005 Share Posted March 24, 2005 what does it take to switch this carbed EA81 to fuel injection? from what i have been reading the SPFI manifold will fit the carbed EA81? what else do i need to know for this carb-to-FI swap? what year SPFI donor vehicle should i be looking for? the EA81 comes out of an 85 Brat and will go into a VW bus with a KEP plate Quote Link to comment Share on other sites More sharing options...
bluesbug Posted March 24, 2005 Share Posted March 24, 2005 I highly recommend going with the weber carb conversion.My 61 panel van has an EA-81 weber setup and the power band is great.Easy to work on too! Bluesbug Quote Link to comment Share on other sites More sharing options...
dansvans Posted March 25, 2005 Author Share Posted March 25, 2005 OK , do those still sell new? or do i rebuild a used one? what cost if new? does the weber only fit on a modified SPFI manifold as i have been reading about? or is that unnecessary? how did you work out the exhaust? it almost looks like the stock front pipe can be used. assuming it can, the rest would be a cinch!

bluesbug Posted March 27, 2005 Share Posted March 27, 2005 Put a wanted to buy add on the marketplace on this site.You can probably find a good used carb/manifold.Search in the older suby area for WEBER and get addl info....For my exaust I cut off the two pipes about a foot down from where they bolt on the engine,and later had a muffler shop add a Y pipe,a flange,a turbo muffler,a u turn and a side exit with a chrome tip.It looks and sounds great and was $150 well spent..

subieman Posted March 27, 2005 Share Posted March 27, 2005 NVBigBlue is doing this swap as we speak. Here is the link to the thread. http://www.ultimatesubaru.org/forum/showthread.php?t=31356 Quote Link to comment Share on other sites More sharing options...
DJ_Kuehn Posted April 20, 2005 Share Posted April 20, 2005 You can also use a Holley 5200, which are very common, and can still be bought new (reman) at your auto parts store. It is very similar to the Weber 32/36. Holly licensed the design from Weber. It is used on pintos and late 70's style mustangs. the only catch is that you'll have to make an adapter plate because the bolt pattern is different. I went with this setup because it was WAY cheaper than a new weber and parts are easy to find. Quote Link to comment Share on other sites More sharing options...
TomRhere Posted April 21, 2005 Share Posted April 21, 2005 If you do go the Weber swap, I would swap an EA-82 carbed intake on your engine. You don't really need to do it, but the EA-82 intake, has a larger opening beneath the carb, and I do believe the runners are larger too.

Snowman Posted April 21, 2005 Share Posted April 21, 2005 http://www.ultimatesubaru.org/forum/article.php?a=61 That's the link to the link to the SPFI conversion manual, which should answer a lot of your questions. Lots of people on the USMB absolutely love their Weber carbs. That's why I bought one for my car. I had really bad luck with it so I converted to SPFI, which I have been much happier with.
