L20B,its not the motor that came in that car from the factory.Just under 2000 cc's.Stock would have been L16,1600cc.

you are right! it's a B, does that means it's a 2.0 L ?

Indeed, well 1986 cc's I think.

but a 2 liter. what about the head? the casting mark should be on the spark plug side, right above the block. should be something like U67 or 210 or V912, the V912 head is garbage and you should totally give it to me.

the head mark it's A87 what that means..?

It's just the casting mark on what the head is, from there you can tell valve sizes, intake/exhaust port sizes.. etc.

Though the only thing you can't tell with out taking the head off is whether it is a closed chamber or open.

 

Open and closed respectfully:

 

 

You see how one is a full circle, and one is kidney shaped?
