Is there a late model shoulder harness seat belt system that will bolt into my 240 z. I'd like to find a retractable type.

thanks for all the advice, I'm in search for a good pulley I guess....

I guess the only remedy is to replace. This may sound stupid but could you weld it into one piece or would the lack of flex be to hard on the crank key.

Has anyone heard or experienced a crank pulley coming apart? The rubber between the damper and pulleys is deteriorated but it is hard for me to believe it would come apart. Actually, before this was pointed out to me, I didn't really realize these were two different parts bonded together. Maybe I'm paranoid but I need some feedback on this. I would buy a new euro pulley from msa but I want to try and keep ac.

That is Murphys law hard at work. If these wires were already assembled I guess I would go back to checking connections and tightness of the plugs and their tips. Good luck!!

My machinist is charging me 225$ to do all the above. I don't how many revs it gains you but if your not sure of what you have as far as amatched set I would consider it.

Any advice on best price and availability on new pistons for my 240 motor. My machinist was ordering from federal mogal but I guess it went back order.

I think I would try replacing the spark plug wires if you haven't already.Some how the shielding my be screwing with your spark. Are these custom made wires?

I'm rebuilding a 240 motor and need some help. I took my machinist my crank pulley and he said it looked scary. the embedded rubber was in pretty bad shape and he was concerned about its stability. I want him to balance everything but he thought I should try and find another pulley. I'm up for ideas. This is my first thread so I hope I'm doing this right.
