While spending too much time on Yahoo Japan auctions, I spot this;

I presume a spanner so you get the right torque setting.

Yes, what that is is a spanner for torqing the headbolts of a s20 engine to about 65Nm..  nothing special i think..

Funny is to start the "read this website to me" in Japanese.. and even more fun is to change the website to another language and let "her"read that! Sounds very funny!

 

I take it the black and white image is from Nissan's workshop manual, so it could one of the specialized tools that is listed within the manual.

There are specialized tools for L series engine and for the S30 body listed in Nissan's workshop manual, but virtually no-one uses these, let alone seen them.

That's what I mean by sepcific.
