if you patient, with US companies ask them to ship not air-freight, may make it cheaper (if they'll do it)
Yes thats very true with MSA, they quoted me about $1200USD to ship over a full pallet (4-5 foot hight) with a bodykit and a heap of chrome stuff for the engine bay, only about 4-5 weeks shipping too instead of this 3 month stuff I hear about on sea shipping.
I also think there are some good parts still in Japan - and shipping from Japan is alot less that from the USA. I picked up my Turbo Manifold adapter and turbo dirt cheap, and another 3L Soarer single turbo unit for free with a deal my old man got. I see alot of L series mods because they have the original Skyline's over there which are collectors edition and the Japs seem to know what they are doing when it comes to modifications.
