Yes but you need 2 solenoids, one for nitrous and one for fuel. Motor work, like forged drop in pistons and some machining skills. Dry systems are the easiest way to go and you can still make 50 to 70 hp on the stock motor

Sky is the limit with either kit!
Wet kit...simpler to install and tune, and easy to change around. Still good to have a tune and a second map for it when using. THe second map will retard the timing and such. On stock motor and stock compression.....60 shot is prob limit. Do valve springs, studs, rods, up the compression, and even race fuel.....60 to 160 is do able. That big of shot you will want a progressive controller to bring it in soft in stages.....the full hit would not be untill bottom or 4th or something.
The dry shot is very simple to add if fogging the air box with ONLY a 40shot or less. FOgging the box will be notice ( colder ) temp and the ECU will add more fuel automatically. NOW you want more with a dry set up and some computer wiring.......: Guys have done 100+ shots dry BUT, Direct port ( fogged direct into/down into the throttle bodies), Custom map tuning, retarding timing, larger injectors, larger fuel pump..ect...fuel is add in by the stock-method fuel system( thu Highly modified). See where Im going with this. For the BUSA...BoostbySmitth has some GREAT ECU flashing hardware that will controll EVERYTHING from your stock ECU: when NOS armed.swithes over to a second custom tuned MAP, it retards the timing, ups the fuel psi, controlls st gear lock out, WOT switch..ect, ect.
Big spray meen a lot, watch you top HP limit for the motor. For a BUSA...the RODs max at taking 250-260HP. Basic saying...Im dyno at 155HP now ( but motor is prob 175hp...330OSD take off about 20HP) and did top end motor work to get me to motor HP of 195..then put 80 shot NOS into that = Im 15-20HP OVER what the RODs will handle....prob go BOOM.
FOOD for thought.
