turbosubarubrat Posted January 30, 2013 Share Posted January 30, 2013 i found out that the distributor off a ea71 fits on it correctly but should i use it? it fits perfect without hitting anything and it turns freely with no problems when i turn the engine over with a ratchet. i have 2 types that work for and one that doesnt because the shaft is too long. the 2 that work are a self igniting(no wires)and a electricly controlled one, what one would be better to use?

GeneralDisorder Posted January 30, 2013 Share Posted January 30, 2013 You need the correct four wire EA81T distributor that has the proper connections for the knock control unit. You can't use any non turbo distributor as your timing control will not work correctly. Turbocharged fuel injection needs the ability to retard the timing in response to a knock sensor. None of the two-wire distributors have the ability to run the knock control. GD Quote Link to comment Share on other sites More sharing options...
turbosubarubrat Posted January 30, 2013 Author Share Posted January 30, 2013 where can you get the distributor at? Quote Link to comment Share on other sites More sharing options...
rdweninger Posted January 31, 2013 Share Posted January 31, 2013 Not sure if you have the old non-working distributor or not... But if you do, you could have it rebuilt. I mailed mine in on Monday, they received it Tuesday, and called me today to say it was done. I'll have it back tomorrow. Hope this helps. Ron W.

naru Posted January 31, 2013 Share Posted January 31, 2013 where can you get the distributor at? It is a Hitachi D4R82-03,Subaru 429878710 Both #s are stamped in the housing. Rockauto has a rebuilt one,or you can sub an early ea-82t disty w/small modifications. Quote Link to comment Share on other sites More sharing options...

GeneralDisorder Posted January 31, 2013 Share Posted January 31, 2013 You would have to change the drive gear which means drilling a new roll pin location in the shaft and the drive gear must come from an EA81 Hitachi distributor. Then you have to cut off one mounting ear and move some wiring to make enough clearance to turn the disty once its installed.... I wouldn't call them "small" modifications if you have never drilled precisely located roll pin holes in shafts before..... Also the only EA82T candidate that will work is the 85/86 models. After that they went to optical and ECU controlled timing instead of the separate knock control units. GD Quote Link to comment Share on other sites More sharing options...
