Pistons
----------------------------------------------------------------

AE # 20907

Pistons are also used in:
J13 engine - 1299cc
        Datsun 520 - 1965-1969
        Datsun 521 - 1965-1967
	Datsun 411 - 1965-1968

Similiar pistons used in:
A10 engine - 988cc - AE # 19659
        Datsun 1000 - 1965-1970
  Note: 1.283 compression height with flat top height gives 8.5:1 CR

A12 engine - 1171cc - AE # 19690
        Datsun 1200 - 1971-1973
        Datsun B110 - 1971-1973
  Note: 1.279 compression height with dished top gives 9.0:1 in an A12
        engine, CR would likely be lower than stock 8.2:1 in an A1 engine

A13 engine - 1288cc - AE # 20228
	Datsun B210 - 1974
  Note: 1.283 compression height with dished piston gives 8.5:1 in an
        an A13 engine, CR would likely be lower than stock 8.2:1 in an
        A1 engine.

Other possibilities:
745 cc Norton - AE # 19145
        P11, P11A, N15CS, Matchless G15CS - 1964-1969
  Note: Has 0.687 pin and 1.543 compression height.  Would need rod eye
        honed 0.002" and 0.263" removed from piston crown.  The piston
        has valve cutouts on the top, so it might be possible to remove
        that much, or less could be removed to raise the CR.  There was
        also a 7:1 version of this piston made that is not listed here,
        it probably has a compression height very close to what's needed.
        Original Hepolite pistons for these bikes are expensive, but
        there are some very good quality low cost japanese pistons
        available for British bikes these days, although the 7:1 version
        is not likely to be reproduced.

MG/Triumph - AE # 19708
MG/Triumph - AE # 20139/V1 (California model)
        MG Midget MK4 1500 1975-1980
        Spitfire 1500 1973-1974
        Spitfire 1500 1975-1981 emissions control
  Note: 2.8995 bore, 1.287 compression height, 0.813 pin
	These pistons would require a 0.64mm (0.0255") overbore, which
        is very reasonable, but the rod eyes would need to be reamed
        0.126" oversize, which might be too much.

A12A engine - AE # 21508
        Datsun 210 Sedan - 1980-1981
  Note: 2.9527 bore, 1.2850 compression height, 0.750 pin
A12A engine - AE # 21533
        Datsun 210 Sedan - 1982
  Note: 2.9527 bore, 1.2805 compression height, 0.750 pin
        Pistons for the E1/J13 engines come in up to a 1.5mm overbore,
        this piston would require a 2mm overbore, which might be possible
        if the cylinders are thick enough.  The rod eyes would need to be
        reamed to 0.750.  Both of these pistons are dished and would
        probably give a CR below the stock 8.2:1.
