Hi everyone, sorry for the lack of knowledge on the subject but I'm interested in replacing the engine of my 98 lexus gs300 with high miles with a 04 GS300 with less miles. This will be all stock so should I be concerned with many modifications and different wire connection types? I don't have the 2004 GS engine to be able to tell. I just want to be able to take out the old engine and put in the new replacement just the same. Thanks

if its like the IS motor i just put in my 99 you will have to reuse your engine harness and intake manifold and throttle body.
