Well i have an 03 GT, Throttle body, intake, pulleys, LT headers, X pipe, Catback, Custom port/polish mainfold, plenum, elbow, and stage 2 cams. i was planning on installing stage 2 aluminum heads (patriot, most likely) getting some granatelli/msd coil packs, CSR water pump. I was debating using a small shot of nitrous 50-75 shot, wet. If i decide to go against the nitrous kit, should i upgrade the injectors/pump/ect? and if i go with the nitrous kit, whats the fuel specs i need to look into, Thanks!
