I'm not telling you get nitrous or how to tune it, but I thought I should mention zex also now makes wet kit's, and your car may be one of the applications. That's all I'm saying, cause I dunno much about N20 and I don't wanna be responsible for detonation. But from what I heard, upgraded exhaust is good if not almost a necessity for n20. In an issue of HCI they say N20 sprayed engines respond well to exhaust mods, because of the increased oxygen. Also check into the zex spark plugs they'll prolly go good w/ the zex too.
