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?
