JDM engine maintenance parts?

[twitchy]

I would sooner build my KA than swap an engine into my car...but for curiosities sake, where do you get things like belts, plugs, thermostats and oil filters for a swapped JDM engine? Like if you put a skyline engine into your 240 where would you go for these parts?

rb stuff is harder to find
but SR stuff is very very easy to find for maintenance items.
