i got a 07 civic si with bolt ons and im looking to do some nitrous do i need to upgrade fuel pump and injectors sience they are factory. Im also looking to do 100 to 120 shot on the stock motor if its possible
easy young bucky. injectors should be fine im on stock injectors with a 100 shot direct port which id recommend to you and honestly youd want to upgrade injectors at about the shot you want from the looks of it a 125 is highest youd want to go for being safe but direct port like i said. yes upgrade your fuel pump to walbro 255 or deautschwerks 65c and youll want 1 step colder plugs gapped bkr8eix read all the threads about nitrous then have it prof tuned. im still having some problems because i need the fuel pump which is fairly cheap. but with a 50 shot and bolt ons i was at 311/254 so best of luck youll want a few things my whole setup has cost me about 1500 i like dynotunenitrous personally.
I've been really wanting to do a nitrous setup really bad after i get cams and the other things i want and i was wanting to run 50 on streets and 75 or 100 shot on strip i want to stay on the safe side.
