There is a NOS kit for your car. It's the only one I have seen for the TBI. I don't know if any others can be made to fit or not. It's $550 dollars and adjustable from a 75-125 shot. On a stock 305 TBI most guys say don't go over a 100 shot just to be safe. Your not the first person to ask this question.
there are a few guys that i have seen running 125shots on completely stock 305 tbi's. with a few mods there was one guy running very low 13(like 13.1's). as long as it si a wet system(it sprays the nitrous and fuel in together, like a plate system usually does) it is not as bad a shock to the bottom end of the motor and you can get away with a huge squeeze. i know at least 2 LT1 guys running 150shots on stock motors with wet systems.

I have installed and like this system: http://www.bgfuel.com/nitrousworks/frames/GM/GM_TBI.htm also I think this system has potential in a TBI car given the jets are changed to a TBI fuel pressure friendly set; http://www.holley.com/HiOctn/ProdLin...densystem.html the new top shot system.

i was considering getting that kit but my car has 101k miles on it...would it still be safe to run a 75 shot or maybe a tad more? and would a 75hp shot be worth having? im about to put a TBI edlebrock manifold on it including the mods in my sig...what you all think?

dont for get the TB swap from holley (670 CFM) and the possibility for a 350 swap (with the right cam and maybe 350 chip) I think 75 would be fine also check out http://www.outlawperformance.com/gmtbiall50hp.html
