Contact Raw Brokerage (Coolwhip). If he doesn't have one, let me know and I can get a junkyard one from over here.

breaking in half? Something had to have been locked up inside of it for that to happen.. I don't see any other way that happened.

look at the crank shaft pulley as well to see signs of damage. As cases where this has happen the motor was hit in the front. (check your CAS bracket as well as it is prone to breaking under these conditions).

I will get some pictures for you guys here soon. It's pretty damn crazy. There wasn't anything locked up on it. it still rotates freely. Thanks for the help all. I'll try and get in touch with coolwhip.

actually happened to me a few times. i though it was my bracket but it turned out to be that my timing belt was too tight. you might want to check that.

When you say hit int the front,do you mean like in a car accident?Will it be ok to run it like that,i mean what will keep it from happening again?Im paranoid now since my CAS bracket is broke.

Mine was cracked when I got the motor. Had it TIG welded and it cracked again when I wrecked the car. Got it welded yet again and havent run the motor much. I went ahead and bought another one just in case it cracks again. I never had any CAS failures though.

I'll have to see if my CAS mount has any cracks. I think I'm just going to get a new sensor from nismoparts. You guys think it could just be a factory defect?

Also does any one know if i can hook up an OBD1 to my 92 240 RB? I might just end up buying a mini laptop with one of the engine management programs on it but even still.
