Caboobaroo Posted April 9, 2006 Share Posted April 9, 2006 So I really need this question answered before I start putting the drivetrain into this car. If I used an EA81 solid lifter engine, and a EA81 single range 4-speed, will the stock '78 Brat driveshaft work without being modified? If noone knows, I guess it'll be time to see what I have to do:rolleyes: Quote Link to comment Share on other sites More sharing options...
Zefy Posted April 9, 2006 Share Posted April 9, 2006 you could measure it... measure from the motormounts to the output shaft... if they are the same for the ea71 and ea81 then i'd think you'd be good... also... you might want to PM 'subaru jim in maple ridge' he's done this conversion... and as far as i know the only part left to do on his brat is the exhaust...

MachineAgeVictim Posted April 9, 2006 Share Posted April 9, 2006 are the splines the same? Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted April 9, 2006 Author Share Posted April 9, 2006 hmm yes, good idea to measure it. Didn't think of that. I do have the engine/tranny in the parts car so I can go measure it today:banana: Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted April 9, 2006 Author Share Posted April 9, 2006 yeah splines are the same but the EA81 axles are about 3/4" longer but they work in a gen 1 vehicle. Quote Link to comment Share on other sites More sharing options...
