Anyone ever heard of it? I picked up a brand new F23A3 block off Craig's List, which the guy had bought from Honda some years ago, but I can't seem to find out anything about it. I found A1/4/5/7, but only a few overseas mentions of the A3

 

So no one's ever seen one before?

 

is that the one with the non-removable exhaust manifold?

 

im not sure if the DX motor was A3 or A5. either way, you might have that motor.....which if its just the block is no problem, since vtec is in the head anyway.
