hey im new to the whole fuel injection thing i got a 91 gt mass air car and i need at least a 100 shot! my problem is that i have a nitrous kit (performer rpm 100-250 plate kit) as you know this is a plate style system for a carberator. now im wondering if i could use a fogger nozzle insted of the plate and place the nozzzle in front of the throttle body. the kit is a wet kit so i plan on running a secondary fuel system for the nitrous. i was told that the computor would "see" the nitrous in the manifold and try to make it richer this would be bad but id rather run rich than lean. or could i put the nozzle in front of the mass air sensor? thanks for any help

The fogger nozzle has to be a set distance from the throttle body, and could vary between manufacturers. Call the manufacturer of your brand of kit and they can tell you how far from the TB would be optimal. Not in front of the mass air meter! You will have to get a wet kit fogger nozzle and you can supply the fuel solenoid from the test port on your existing fuel rail. You can also purchase a plate made for your intake as well, at least that is what I would do if I installed it. I have had a fogger in the past on a different car, didnt like it.

 

do you think the test port will folw enough with the stock pump or should i get an in line fuel pump to suplement it. my biggest fear is runnig lean. is there a map sensor or manifold temp sensor that i could mess up doing this? iknow i say 100 shot now but you know how that goes once you get greedy i know this motor has factory forged pistons so it could probibly hold a 200 shot but ill probibly stick to150. im not one to use it all the time just at the track or if theres money involved anyhow thanks for your input

I would at least get a adjustable FPR, another pump may not be needed if you have a good one to start with. I would at least upgrade the existing pump to 190. If you go to 150 shot, be sure and retart timing 2 degrees for every 50 shot, so retard 6 degrees. Make sure you have the WOT switch and run it safely to avoid engine damage. It wouldnt hurt to get it tuned as well after the install. If you need someone to talk to, google Nitrous Express, they are located in OKC and can help you with any questions, very knowledgable. Good luck!
