10.3 kgm @ 3,500rpm ~ 74 lb-ft

I am just looking at the brochure for the Canadian 83 Civic and the EN1 is listed as follows;

1,335 cc
72.0 x 82.0mm/2.83 x 3.23" bore & stroke
61 hp @ 5,500 rpm
10.3 kgm @ 3,500rpm (not sure what that is in lbs/ft)
8.4:1 compression ratio

Hope this helps

The EN came in the 80-83 Civic 3dr,5dr and Wagon.The EN was not available in the US.I think they produce about 65hp.

What did EN1s come on, what years?

The heads are different. The EB3 head has a larger combustion chamber and larger valves so it runs domed pistons to get a decent C/R. The EB1 has a 70mm flattop pistons while the EB2/3 have 72mm pistons (EB2 flattop, EB3 domed).

The EN1 is an EB3 with an 82mm stroke instead of a 76mm stroke (both have 72mm bore). An EN1 is basically an EB3 with an EJ1 crank/rods, the factory just did the stroker conversion for you.

Pretty sure everything's interchangable between an EN1 and an EB3.
