98 Version 5 engine into 02 WRX
 

my 02 wrx engine is knocking real bad. i'm guessing this is some sort of bearing failure. it started off quiet but got noticably louder by the time i got home.

anyway i set about removing the engine from the car. engine is now removed, pretty hassle free.

bought an engine from a 98/99 type r - engine was still in the car and was able to hear it going and the car came with a pretty good service history detailing service history and cambelt change and so on.

switched over my inlet manifold to the new engine, also my turbo (vf35), downpipe, exhaust manifold, crank pulley and top cam pulley and also the 2 sensors that pickup these pulleys.

is there anything else i should switch over to make sure the car is 100%? i'm ready for putting the engine in and just want to make sure.

also what would have been the possible causes of my old engine becoming knackered? is there anything i could be carrrying over that may cos this other engine to do the same?

come on guys someone must know
