    A20A3 efi higher compression then the carbed motors
    A20A4 efi rumored to have larger valves, I believe its only found in the later model gen2 prelude Si

    While shopping for a friend, we saw an accord hatchback with an A20A2 carbed.

    was an 86 model.

    What about the BS and BT designation for motors? Were they only used for one year(1986) or more?

    I just swapped out my original motor a20a1 for an 86 accord dx motor with the "BS" designation on the engine block.

    BS = A20A1
    BT = A20A3

    Those are the old style honda codes, they swithed them in 87 i think. You could tell people you have a b series motor swap in there and technicaly be right .

    Its stamped on the block next to the trans on the exhaust side of the motor. There is a little flat out croping that its stamped on, problably covered with 13 years worth of grime.

    a20a4 is also found in some australian and european model accords

    It figures that the carbed motors are labeled BS lol
