This time I am trying to do my Best to help a Friend, Mr. Mariano, who owns a 1980 Subaru GFT-5 Coupé, which came factory with an EA71 engine that features Twin Hitachi carburator setup.
Here is a Photo of his Subie:
Here's a Photo of that Subie's Engine Bay:
Photos of the Actual factory intake manifold:
He is in the middle of the Restoration process of that Subaru, and he really wants to get rid of those hitachi craps that seems like now they're bad beyond any repair, he dreams about to obtain a single carb intake manifold that fits his Subie's engine and fit there a Weber Carb.
He already obtained a 32/36 Weber and the Trans-Dapt 2107 adaptor, also he obtained a Single carb intake that was sold to him as "For the Subaru 1600" which is the EA71, but the intake was longer, so we believe it was for the EA81 ... and he already welded with aluminium the Trans-Dapt adaptor to that unuseful -for him- intake manifold, as you can see...
By seeing this Photos and seeing the Position of the Starter behind the engine, on a side, I want to Ask (To be sure):
► is that a Fat Case EA71, isn't it?
► Does the Twin Carb EA71's comes with Reversed Valves as the Twin Carbs EA81's does?
Here is a Photo of his Original Owner's Manual about the Valves (in Spanish):
Words in spanish over the Valve's drawing means: "Exhaust Valves" while words in spanish under same drawing says "Intake Valves". The main Question could be:
► Will a Single Carb EA71 intake manifold fit right to this engine, or not?
Due to the Lack of Spare parts, we were crossing Private Messages, planning to cut the Upper part of the EA81 intake, along the welded adaptor, and cut the upper part of the Twin Carb EA71 intake, and weld the EA81 part to the Twin carb EA71 one, without touching the Water passage... Sounds crazy enough, isn't it?
Please let us Know your Ideas about that, and the Answers to our Questions, which will be Greatly appreciated.
