I have two 200sx parts motors right now. They use the same chain. If you want to measure the length of yours I can do the same and see if either of mine are shorter

I just measured one of mine. It was around 138.2 mm. It's hard to get a perfect measurement since the chain links like to move but it should be close. It doesn't look like the service manual gives a length spec for it like they do with the cam chain.

I didn't have a 24mm socket either and was too impatient to go to the store. I ended up using either a 15/16" or 1" deep socket, I don't remember. Turn right to loosen
