Found this waiting when i got home..
I was under the impression that i would have to pay duty and GST for these injectors before they would be released, but here they are
They are labelled car parts, but the value is only 20160 yen (under $400 so exempt)
So providing some sort of bill doesn't turn up in the mail which i doubt, then iv got a set of 63516's for $679.82 to my door
Which is almost 1/2 what nzperformance want
Maybe i will have some extra $$ for a brake upgrade after all?
