I think most people who run that use the fogger setup, it injects ectra gas and NO@ threw a spray nozzle. I think it is possible to get more horsepower by director injection. IT allows moreNO@ to get into each chamber then the plate.
Summt sells a do it yourself director port system for around 500, I don't think it includes bottles, just the injectors and jumps.
Good luck if you deside to do it.

I have the Direct Port Kit But it takes some custom work to get it installed correctly. You have to drill holes through each of your runners and then weld a bung onto each runner or just pile up a bit of metal on it. The kit comes with a tap so you wont need that. I wish I had a pic of mine so i could show you. But it was alot of work. Direct Port is alot of work but you can hit your car with a bit more juice and not hurt anything. I am very conservative with my car I could probobly hit it with 200 but I dont like the idea of my stock trans and rear spraying pieces all over the track. The kit comes with almost everything you need except a way to plumb your fuel on a FI car.
thanks gtaboy; is their no way you can get pics?
i have a tpi kit that i use now with the plate system; i'm looking to see if i go the direct port route if it will be "easier" on my engine an setup. mind you it's a completely stock l98 350.
what do think i will need to convert my system to direct port other then the fogger nozzels?
in theory if tunned right i would think it would be better than the plate system because of the proper distribution, am i wrong?
anyone have pics or any other comments on a direct port nitrous system?

Yes Direct port is definitly Better but it has a price.
On the direct port kit there is 4 solonoids. 2 fuel and 2 nitrous. so you will need 1 more of each + you will need 8 Foggers and 16 Jets which gets very expensive. Then you will need 16 pieces of copper connecting tubes which you will have to bend + 4 distrobution blocks and a T fitting to come up off of your Shrader Valve. Then you will need 2 4an lines about 1.5 ft and 4 aeroquip fittings to screw the line into the T and the solonids. oops you will also need a T fitting and two lines for your nitrous. Honestly if I was you I would Stick with the plate setup. Its just too expensive to convert it when you could be spending all that money elsewhere. I am going to borrow my friends digital camera tomorrow so maybe i can get you some pics. I have been meaning to get some pics anyway. But if your into intimidation nothing will scare the crap out of Rice more than beatifuly installed Direct Port setup. Sorry if this sounds confusing I have been drinking tonight.
