Guest Ratty2Subaru Posted August 9, 2003 Share Posted August 9, 2003 does anyone know if the cams are different between the carbed ea82, the spfi, mpfi, and turbos??? I need to know before I put this carbed cam on an spfi motor! (drivers side only!) thanks! Quote Link to comment Share on other sites More sharing options...
Guest GlCraigGT Posted August 9, 2003 Share Posted August 9, 2003 I managed to look this up in a 87 FSM, each version of the EA82 had a different cam. Quote Link to comment Share on other sites More sharing options...
Guest Flowmastered87GL Posted August 9, 2003 Share Posted August 9, 2003 hmmmm I wonder what that cam richie gave me came off of (for my 86 turbowagon) It worked whatever it was off of Quote Link to comment Share on other sites More sharing options...
Guest Ratty2Subaru Posted August 9, 2003 Share Posted August 9, 2003 oh great... so do you think a carbed cam on the drivers side will work with a spfi cam on the pass. side? Quote Link to comment Share on other sites More sharing options...
Guest GeneralDisorder Posted August 9, 2003 Share Posted August 9, 2003 Didn't the SPFI have higher compression? I'm guessing it will work, but it may not produce peak HP. You probably won't notice much difference. One side of the engine will be leaner, or richer than the other side, so it may be hard to tune properly. If you tune for one the other will not be correct. There may be a happy medium where both will run decent, but it won't be perfect for either. GD Quote Link to comment Share on other sites More sharing options...
Guest OH Noah Posted August 9, 2003 Share Posted August 9, 2003 I would NOT advise running two different cams, nor would I advise using carb cams on an SPFI engine. The SPFI engines use a very different ignition timing curve than the carb ones. I believe that that is partially due to different cam timing/profiles. I'd be very interested to know the actual specs for each of the EA82 cams. Quote Link to comment Share on other sites More sharing options...
Guest GlCraigGT Posted August 9, 2003 Share Posted August 9, 2003 I'll see if i can get a snapshot of that section of the FSM. Quote Link to comment Share on other sites More sharing options...

Guest GlCraigGT Posted August 9, 2003 Share Posted August 9, 2003 Here are the snapshots that I was able to get. The first is the basic engine specs which include the cam timing, the second is the lobe heights along with how to ID the different cams. It turns out that CARB and Turbo use the same cam. This info is from a 86 FSM <a href="http://home.comcast.net/~c.moe/cam1.jpg" target="top">home.comcast.net/~c.moe/cam1.jpg</a> <a href="http://home.comcast.net/~c.moe/cam2.jpg" target="top">home.comcast.net/~c.moe/cam2.jpg</a> Quote Link to comment Share on other sites More sharing options...
Guest ccrinc Posted August 10, 2003 Share Posted August 10, 2003 Most importantly, you can't swap from a drivers side cam to a passenger cam: they're different!!!!!!!!!!!!! The left cam has a gear-end that meshes with the distributor. The right cam is shorter and has no such part. Technically, yes, the carb and turbo cams are the same, SPFI and MPFI are the same. But believe me, you can swap back and forth between them all with no problems. And you'll never be able to tell the difference either. But left to right or right to left...ain't happenin' :cool: \ Emily www.ccrengines.com Quote Link to comment Share on other sites More sharing options...
Guest Ratty2Subaru Posted August 10, 2003 Share Posted August 10, 2003 well, it was obvious to me that i couldnt switch sides... i ended up just using the old one that was from the motor... thanks for the info! Quote Link to comment Share on other sites More sharing options...
