    EA 71. Building a rally engine and gearbox. I need some help.

    in Historic Subaru Forum: 50's thru 70's

    Posted · Edited by 1000 Pistes

    I would like to build an EA 71 rally engine for competition use in VHC.

     

    To be noted that accordingly to the F.I.A. homologation form of the Leone of 70s(A22L,A31L,A32L,A33L,A26L)are permitted only the EA 63 and EA 71 engines.

     

    Because of those types of engine are very rare,here in Greece,I would like to collect all possible infos,experiences,suggestions,etc, before starting building it.

    I have in mind to machining the intake ports of the heads to accept twin WEBER carbs,one twin on each head.

     

    I would like to know,also,if the EA 63 heads are most preffered than those of the EA 71 ones.

     

    Furthermore I would like to know in what models I could find 5gear gearbox,compatible with the EA 71 engine.

     

    In the F.I.A. homologation form of the time I saw that there is 5gear gearbox with the following ratios:

    1st   : 3.31 (43/13)

    2nd  : 2.53 (38/15)

    3rd   : 1.96 (45/23)

    4th   : 1.52 (41/27)

    5th   : 1.03 (35/34)

     

    and final drive(CWP) : 4.13 (33/8).

     

    Could i found those ratios in some model?

    Factory Twin Carb Subaru EA Engines were available on both the EA71 (1600) and EA81 (1800), Both engines were defined by a following "S" at the end on their engine codes. This was Subaru's way of calling it the Sports model. The engines were a completely different design to the standard models. The "S" models had Dual Ports and Opposite Valve configuration, which means different cams and rocker gear.

     

    They were available in Japan in the Subaru Leone GSR and in the later RX Models. These engines has Higher Compression Ratio and had ~10% more power output. They were used heavily in the late 70s and early 80s Rally cars.

    When Subaru Developed that Head-Mounted Twin downdraft Weber Carb EA81 engine with Reversed Valves, they already had the Turbo EFi Technology, so very Few of those were made, since Subaru started to sell the "Turbo Traction" Models in the same 1983 year...

    But very Few Twin Weber Carb Models were Available for Sale, mainly in Japan and New Zealand,

     

    like This one, which was for sale some months ago:

    "Making a safe car that is fun to drive”Improving enjoyment by adding safety.

     

    130123.jpg

    “In an age where cars are more common and people who don’t drive become the exception, it is imperative that safety issues are not overlooked. Safety testing methods are sure to evolve and in the near future we may even develop cars that can drive themselves. However, I really would feel sad if people lost the enjoyment that you can get from driving. If the focus of such advancement is limited to safety and the car is totally controlled by computer, car lovers would never feel satisfied. I believe that the second generation Leone has achieved a high level of both primary and secondary safety and I hope that this car can deliver the enjoyment of driving freely.”

    Mr. Horiguchi realized that no matter how much you focus on safety, you must never forget the feeling the owner will get when driving. From now on, we hope to continue the spirit and enthusiasm of these engineers to create cars that allow the driver to experience the enjoyment of safe driving.
