i was wondering how much cheaper the japanese wheels and engine parts are over in japan...if cheaper at all?

It deepends on the part and where you go looking for it. Everything is quite a bit cheaper than the states, just because there is no customs or shipping charges added to it.

oh well im maybe looking for a used apexi SAFC II, and greddy Profec B spec 2...and a whole bunch of other stuff...550cc injectors, intake manifolds...all for the SR20det that is.
