So, I am finally assembling a JDM B18C picked up in 2002... (long story).

Take a look at this picture - and in the center (red/yellow arrow) just above and to the right of the rear mounts top bolt and just left of the starter is a hole in the back of the engine on the surface that mates to the transmission.

What goes there? ; ' )

Doesn't go all the way through, so it appears meant to hold something.. perhaps in a different version or with an auto transmission or ?



Thanks everyone!

 

nutting goes there

 

...and here I was expecting bolting!

 

Chassis?

 

Transmission bolt, bolted onto the block.

 

Must be used by the auto transmission, hmmm? The manual doesn't seem to make use of it...

Thx!
