bt1 engine vs a20a3

[Tref_LXI]

Hey guys i went to the junkyard yesterday and had a blast. I was like a kid in a candystore, but i came upon a 86 honda accord and wanted to check it out. I looked at the engine code and it read bt1, but looked just like my a20a3. What are the differences between the two: 10hp/10torque?

Yup thats about right 10 hp 10 ft lbs of torque.

But the a20a3 has a dual stage intake manfold (88,89)
2 O2 sensors (88,89)
different idle controll and slightly different throttle body (88,89)
4-2-1 exhaust manifold (88,89)
higher comnpression (88,89)
