GOT nitrous?!?!

If you want more efficiency, you're looking at either a plate system (plate between the upper and lower intake) or a NOSzle (sp?) which injects the nitrous and extra fuel where the injectors are. I don't know if they make a plate that fits aftermarket intakes (I'd assume so). Either way, you're talking big bucks. Even though it seems like you have the money to spend, these are also high HP only models, so you better have a well built shortblock to back it up.

My opinion, the intake mount is plenty efficient for a stock short block. Most people will tell you not to go over a 150 shot unless you have forged pistons. Nitrous Express makes the top notch kits, if you really want another kit, but I'd say the Nitrous Works kit is plenty.

from the sounds of it you are wanting something like a direct port fogger setup

I have a friend that used to run the NOS big shot. he ran a 12.0 @ 114 with a 150shot.

i have an nx wet kit on my car and i love it. as said before nx makes top quality stuff. another thing that is nice nx rates thier **** to the wheels, so you have a littl better idea as far as what to expect to the wheels.
