Tips for HP gain?

Is it challenging getting American engine parts in Norway?
it's expensive, anything i order is shipping+total amount then you need to add 25% for tax. So ignition kit costs 150+ 70 for shipping then 55 for taxes. that makes it 275 dollar. And this is on ebay with their global shipping program. If i order anything from summit or jegs directly it'll cost even more for their shipping.
