February 1, 201610 yr Hello fellas. I came across a engine with dual carburetors. I believe I have a ea81 built by nsi airplane company with the dual carburetor setup from a Japanese rx. I really need a vacuum diagram for the dual carburetor setup. If anyone can help me out it would be much appreciated. Thanks. Justin Edited February 1, 201610 yr by justinthesubie
February 1, 201610 yr I can find pictures but no FSM material sorry http://www.ultimatesubaru.org/forum/topic/110449-sourcing-parts-for-a-dual-carb-ea-81-updated/ http://offroadingsubarus.com/ea81dc/ I hope this helps TOONGA
February 1, 201610 yr how many vacuum ports and devices have you got to deal with ? I think mine are very minimal such as for the vac advance and not much more from memory ??
February 1, 201610 yr Author Not really much there. Vac valve for the choke i think. Two other ones off of the carb just going nowhere. My choke linkage is not hooked up either. Trying to get pictures now
February 2, 201610 yr Author After looking really close to the pictures given and my setup. I think I got it pretty close to what it should look like. It runs but the carburetors will probably need rebuilt. Very excited as this is the only one I had ever seen. Hadn't seen the nsi motor, then researched it online. Hadn't seen the dual carburetor setup, then researched it online. Lol. I got this setup in a car with a ton of other subie goodies. This is the only intake that fits this motor as well <iframe width="480" height="360" src="http://s149.photobucket.com/user/justinthesubie/embed/slideshow/Mobile%20Uploads"></iframe> Edited February 2, 201610 yr by justinthesubie
February 5, 201610 yr Wow pretty jealous of that. When i had a EA81 subaru i was looking for one of those motors. I must have looked for three or 4 years on and off and never did come across one that was accessible to me. Good luck with it.
February 5, 201610 yr Author I can't wait. Should be a lot of fun to drive. Though it would be nice if it was a rx motor. But this one is supposed to have 108hp
February 5, 201610 yr Roughly speaking here, but 30 HP over a stock EA81 engine is nothing to complain about. I'd be "Happy" with it.
October 24, 20169 yr I have the same setup in mine runs beautifully I'll snap some pictures of the carb setup to give ya something to go by for yours if you'd like. Edited October 24, 20169 yr by 83leone
