I would get the wet system because you will not have to compensate for fuel when the nitrous is injected. A wet system is a safer bet. Installing a kit is fairly easy. Just make sure you price around. A complete kit should take no longer then 4 or 5 hours to install if its a reputable shop with experience.

good luck

so all i would need is the nitrous kit? Do i need to upgrade or do anything to my engine to make it ready for nitrous?

I had actually designed a full kit similar to emeralds but I just have been way to busy to start it. I will tell you the the only safe was to fit any kind of decent sized turbo on the SC is to cut out the spare time well. As long as you can do your own welding cost for pipng and stuff won't be bad at all. Biggest problem I ran into is where to run the IC piping once you get up towards the front of the car, and how to securely mount the turbo.

A wet system is not always a safer bet. If you do the right thing on the Dry system it's safer. The right thing is upgrading the fuel delivery system. The Wet systems are always suject to puddeling the fuel in the intake. Turbo Teg here had that problem and luckly only blew up the intake Manifold.

Safer is the Dry system, with cloder NO2 spark plugs. High flow fuel pump and APR. And a Hobbs safety switch which will not allow NO2 spray if it does not detect a certin PSI fuel pressure.

Well, to each there own. If it works for you then I would say for him to copy your setup. My experience in the nitrous department is with boosted cars that we ran wet systems on or setups for just getting the turbo spooled up. Either way its going to haul some *** after he gets it in there. As far as systems to go with. I am a big fan of the ZEX system mostly because of its clean installation. But once again that's just my opinion.
Does the sc400 have a fuel return line?

Sorry to revive an old thread (better than starting a new one):

I was over on soarer central and they had a link to lextreme. How big of a difference will swapping the stock injectors with 7mge injectors make.

http://www.lextreme.com/7mge.html

i will also be installing a safc controller.

is it worth it?

I dont think you want to change injectors if you are not boosting 7+ lbs. The stock are plenty big for a NA application.
