would a s/c out of a 2000 xjr fit on a 2001 xjr?.. i dont see why not... they are both eaton m112?

 

There was certainly no model change 2000-2001, and no engine changes AFAIK. Only the possibility of small production parts mods might cause a problem but I doubt it in this case. You need to compare the replacement S/c with what you have on the car. Also try internet search for a S/c for your car. The suppliers normally list the model and year ranges the various ones fit.

 

You are safe, they interchange.

 

All M112 superchargers from 1998 to 2003 XJR are the same. They rarely fail but the plastic drive couplers do (rattle). I have replaced the drive couplers with the green nylon replacements sold on eBay with the 2 bottles of GM lube fluid.

cool.. so im good.. the one that im going to buy, the vehicle had 64,000 mi on it.. do u guys think i should change the coupler on it just to be sure that it wont fail?.. the s/c that i have on my xjr.. well.. it sounds like there a can full of rocks.. i replaced the coupler and it still sounded like crap..and i have tried to find a place around here that has a press so they can rebuild it.. but i have failed..so my only option was to find an oem and pray that was the problem.. but its def coming out of the s/c
