I have been looking seriously at running nitrious. What I was thinking of doing is picking up a spare intake manifold from one of the guys selling them on this site, then installing all the plumbing for a direct port system onto it while its off the car. Then I'd just swap it out when I put my new head on the motor. I've only heard of 2 people running a direct port setup on the boards, nokeone and mastakillah I think. Anyone have any opinions on this? I'm leaning toward the NX 80004EFI kit, jetted for a 50 shot, at least until I get some experience with tuning the fuel.
