Loyale 2.7 Turbo Posted November 22, 2011 Share Posted November 22, 2011 Dual carb engines has different Heads on them, the Valves are located on the opposite side than the Single carb counterparts; if someone just Swapped the Dual Carb intake over a Single carb engine, it won't be any performance gain, just a Double carb tune up and Synchronization Headache. I Kindly Suggest you to post pictures of the engine and the whole car to help you identify it. Kind Regards. Quote Link to comment Share on other sites More sharing options...
knewsubiefan Posted November 22, 2011 Author Share Posted November 22, 2011 how do you post pics on here Quote Link to comment Share on other sites More sharing options...
6 Star Posted November 23, 2011 Share Posted November 23, 2011 To post pictures, first you must have uploaded your photo to a hosting site; such as photobucket, facebook, etc.. Then, when typing out your post, copy the url of the image from your hosting site. From there, you click the little symbol above the posting you are making that looks like mountain peaks and a sun. Paste your image url in there, and you are set to go. More info like this can be found in the FAQ. Quote Link to comment Share on other sites More sharing options...
hatchsub Posted November 24, 2011 Share Posted November 24, 2011 how can i tell if my twin carbs are factory on my ea81 1983 rx coupe also i have a funny knocking coming from somewhere it doesnt happen when idle so i crossed out the engine so was thinking its from the drivetrain any ideas would help me heaps Im not sure i understand the question. The EA81 RX (yours) would have had dual carbs from the factory. They were dual hitachi's hooked up to a single rod linkage system so they worked in unison. The motors also had reversed valve heads (intake valves were in the center of the heads instead of exhaust valves) and a reversed cam to go with the heads. If you do a search for "ea81 rx" or something similar on here you will find a few posts about it and most of them with me in it lol. I have wanted one for a long time but gave up.

the sucker king Posted November 26, 2011 Share Posted November 26, 2011 And 4WD with rear plate LSD, disc brakes all round and rear anti-roll bar. What was the gear ratio on the LSD? Hey Knewsubiefan- You are gonna have to figure out posting pics, cause you just can't leave us hangin' here! Did you look to see if your rear differential has a LSD tag on it? gear ratio should be on it too. Quote Link to comment Share on other sites More sharing options...
