kudos do a kit, if you want everything, which i think was relatively well priced when i did mine (although i didn't get it from them in the end). i did oem waterpump as well as timing belt also fwiw.
coilpacks, if going oem, hit up amamiya... like literally half the price, but just gotta wait for shipping. i couldn't wait when mine were on the way out sadly... (was before i did my major anyway) but sounds like yours are still in good order in the mean time!
edit: also if as if mr chef says you go gt hyper, it's pretty local since it's in springy (and i think you said you're in rowville)
