i have a 4.0 se 98 RR and i just wanted to know can you install a 4.6 hse 2002 motor

 

you can do it but it will cost alot of green backs,wiring harnesses ecu's,gems to bosch,have fun!!

 

You need a GEMS 4.6 ,the welded in crank sensor mount is different from the Bosch, you can change them from block to block (weld aloy)but if you can just get a GEMS 4.6 , alot less involved , forget about using any of the bosch injection items ,all of your stuff will swap over without any problems,with the exception of the sensor mount.
