if you go to Japan can check it out the price....heeeheee i know
that their auto shop is very big. Ever see a big exhast pipe that
can put your whole head in, install on to the nissan SX180 (japan
car, s'pore model is SX200). 
i think you can look out for the hyper Voltage system &
grounding cable (high quality type with gold plated lug). if i am
not wrong, near to chiba ken....heeheeeehee
