Looks great man, not sure how far you are into your build but a few places here in jhb that you could use for future resources is Japan auto which has tons of motors for our line of fun toys, turbo toys as well but are sometime a tad more pricey, import wise you could use import parts which is also expensive but some of their stuff is relatively priced. as for other parts im still finding sources myself.
hope your build brings you much enjoyment.
