I have been trying to find more and more info on these due to the performance gains as well as the rarity and bling factor... my problem is finding someone to get them from who is reputeable.. I looked into the sos ones but they are to tall for my DF engine cover if at all possible I want a set that could hid undernieth that due to legality reasons. I have hesitated on turbo due to all the things I would have to remove to ref it if ever needed, this would be significantly easier considering. 7000 sounds like every other power adder on an nsx so I am not surprised...
