mkoch Posted June 17, 2020 Share Posted June 17, 2020 *Two* Hitachis... my god, why? Quote Link to comment Share on other sites More sharing options...
Step-a-toe Posted June 17, 2020 Share Posted June 17, 2020 Well, back before EFI or mechanical fi , more carbs looked better than one sounded better and drove better right up the rev range. So at about 130 kph the loud pedal was only lightly squeezed instead of mashed to the floor and felt like had so much more to go Quote Link to comment Share on other sites More sharing options...
old sub freak Posted June 20, 2020 Author Share Posted June 20, 2020 Brats made for Japan had duel carbs.when we were buying low mile engines we always got the ones with duel carburetors...just for the coolness of it and they sure had more power...So.... i found two choices...one. hitachi ...carburetors made in China for $150 bucks or number two New old stock from japan for $600 bucks...And i know you get what you pay for but.....$300 compared to $1200 is something to consider.. so....any thoughts? anyone ever used a Chinese Hitachi ? Thanks and stay safe ,todd Quote Link to comment Share on other sites More sharing options...
Step-a-toe Posted June 20, 2020 Share Posted June 20, 2020 You found Chinese made versions of Hitachi ??!! Linky?? The dual carbs on EA81 were a 306 which I thought were a 1600 EA71 carb , differing from EA81 Hitachi number I know not Quote Link to comment Share on other sites More sharing options...
old sub freak Posted June 21, 2020 Author Share Posted June 21, 2020 yea,he didn't have real info about them other that it was a stock Hitachi. you can't beat $150 bucks but.......I was hoping to find someone that got one and see if its worth anything .

It wasn’t just the twin carbs that did this. Those imported engines would’ve been the EA81S - exhaust and intake ports were swapped around to the way the EA82 runs (intake valve are the inner, exhaust on the outer), so a different cam was used to facilitate this. I don’t know of any other differences in the block etc other than the cam. It could have been a mild cam spec over the regular EA81. Carbs were just part of the ingredient list for the power delivery. Cheers Bennie Quote Link to comment Share on other sites More sharing options...
Step-a-toe Posted June 21, 2020 Share Posted June 21, 2020 (edited) I want to know what differed to make the EA81S spin out to 8,000 rpm ! Oh to be in a position to do a Safari ( ala EA81 with those special after sale, Subaru supplied heads with IDF48? Weber's) to an EA82 , but that gets into big cams, solid lifters, adjustable by shim only .... that Chinese Hitachi seller not named Ali - son of Mr and Mrs Express?
