tscinmd Posted February 21, 2005 Share Posted February 21, 2005 On ebay http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33615&item=7955156363&rd=1 Is there any difference between the JDM ea71 and the version released here? THis would make an excellent replacement for my motor, as the miles are low. Quote Link to comment Share on other sites More sharing options...
85Sub4WD Posted February 21, 2005 Share Posted February 21, 2005 It should be bolt-on assuming it is of the same/similar year. However there were more options and different versions of JD cars - so I cannot say yes for sure - at most the difference would be in things like mounting brackets.

moosens Posted February 21, 2005 Share Posted February 21, 2005 Is you EA71 pre-'79? The fittings on the Air injection is different.Also the starter is top center on the older ones.This one is off to the side like all other EA81 ans EA71 after 1980??Correct me on the year,please if I'm wrong.Brats with EA71 in 1980 and 81 I believe still use the top starter.

You're right - I know he has a top - center starter b/c he has a 1980 hatch - that engine won't bolt in b/c the starter is on the side - I wonder if the bellhousings are interchangeable? - I bet his intake manifold won't work either b/c the late EA71's used a wider one, like the EA81 and EA82 engines.

tscinmd Posted February 22, 2005 Author Share Posted February 22, 2005 Was looking at the repair manual and the pics of the ebay motor --- doesn't look like its gonna be a straight bolt-on .... damn ... Quote Link to comment Share on other sites More sharing options...
tscinmd Posted March 3, 2005 Author Share Posted March 3, 2005 Well, my brother bid on this motor without my knowledge ..... so looks like 90 percent chance we are going to get it ... can we just use the head and other goodies off this motor and put them in the EA71 that is in the hatch now or are there going to be some differences?

85Sub4WD Posted March 3, 2005 Share Posted March 3, 2005 You may be still able to use it if you transfer the bellhousing onto it from your old motor. I don't know about intake ... Quote Link to comment Share on other sites More sharing options...
tscinmd Posted March 3, 2005 Author Share Posted March 3, 2005 Yeah , i was looking at that too ..... my girlfriends brothers and father are all master welders, so we might be able to fab something. Quote Link to comment Share on other sites More sharing options...
85Sub4WD Posted March 3, 2005 Share Posted March 3, 2005 A better solution would be to grab an intake off an EA81/late EA71 out of the JY - heck, even an EA82 manifold will fit - the coolant hose is routed differently tho. Fabricating something out of your intake would be VERY hard to do as there are coolant passages in it - a JY bolt-on is your easiest & most reasonable solution.

tscinmd Posted March 3, 2005 Author Share Posted March 3, 2005 That is true ..... I didn't relize how complicated it was ... they make intakes all the time for race bikes, but these are hell of a lot different. Quote Link to comment Share on other sites More sharing options...
SUBARU3 Posted March 3, 2005 Share Posted March 3, 2005 It's easy. The older version flywheel cover/ rear cover interchanges to ALL EA-71s. So does the intake. Just take the JDM down to the long block and rebuild with your stuff. I've done many! Todd Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted March 3, 2005 Share Posted March 3, 2005 but the JDM EA71 motor to get is the high compression motor. It has a lot more power and only likes to run on plus or premium gas.... It cost a lot to put gas in my Brat after I put that motor in there... Quote Link to comment Share on other sites More sharing options...
tscinmd Posted March 3, 2005 Author Share Posted March 3, 2005 Sweet ..... if we win the auction , I'll have a nice hatch .... Quote Link to comment Share on other sites More sharing options...
tscinmd Posted March 4, 2005 Author Share Posted March 4, 2005 If this engine does come through for me, about how long and how much would someone charge to put it in? We were going to do it with the help of some friends, but I just don't have the time to do it right now with work picking up. And my friends that were going to help are leaving for vacation around the time that we are planning on doing the project. If anyone is in the Western MD, North Central WV or South western PA areas and would be willing to help me out, I could possibly put a new computer in the mix ..... just built one and its sitting in a corner gathering dust DVD Burner and all ..... I know computers like the back of my hand , but older carbed cars are new to me. Quote Link to comment Share on other sites More sharing options...

tscinmd Posted March 4, 2005 Author Share Posted March 4, 2005 Do the dual range's bolt right up to the stock differentials and shafts? Quote Link to comment Share on other sites More sharing options...
85Sub4WD Posted March 4, 2005 Share Posted March 4, 2005 Short answer - no - but it should not be a very hard conversion to do I know it will bolt right up to the side-mounted starter bellhousing on that engine you are getting - I think the driveshafts for the front end should bolt-up too - I think you will have to grab the driveshaft (must be off a 4WD D/R hatchback) and probably the 4WD linkage/shift linkage as well - clutch setup may be different too - but it is possible, with relatively little difficulty - it you have your driveshaft shortened at a custom place, you may be able to put a 5 speed D/R in - better economy - whatever swap you do, make sure the rear diff ratios for the tranny you are putting is correct (same for both cars) you will need to swap the diff too if it is a difft ratio - probably best to just swap them both Quote Link to comment Share on other sites More sharing options...
tscinmd Posted March 4, 2005 Author Share Posted March 4, 2005 Maybe that will be something to look into once the thing is up and running .... I am going to document the whole process for a website that we are making for offroading .... Quote Link to comment Share on other sites More sharing options...
