Default SC400 1UZFE VVTi differences

"SC400 motor changes"
"SC400 vvti engine differences"
"SC400 vvti motor changes"
"SC400 98 engine changes"
"1uzfe vvti differences"
"SC400 change motor engine halp"

I tried at least a dozen search terms on CL and on google with no luck other than the default intellexual faq page blanket response. There is some information about model year to year changes, and I know the VVTi motor has more power and more torque and different valving etc. Is anything else different? I thought I read something a few years ago about the alternator or power steering being rearranged, but I might have just fantasized that after changing the alternator 3 times on my old SC before I realized my power steering pump was leaking onto it lulz.

Anyone?
