Going by the mods in my sig, do you guys think that if I am getting a basic NX kit soon and I will stick to only a 75 shot, will I need to upgrade my fuel system or not? Sorry, I am new to the N2o game, and the search was BS'n me.

 

you don't have to, i would atleast get a walboro 255 then you wont have to worry about it.

 

In tank or in line? I know that in tank would be more of a pain to install, but are the in line fuel pumps just as good or not?

 

Go with the in tank will save you the hassle of wiring and pluming
+ it's not that hard, basic tools + jack and an extra 2 hands.

 

Check my tuning web site for two seperate fuel upgrade write ups, you'll get some ideas and insight. just search roberts nitrous at google.

^ Thanks Robert

 

you should get injectors and have them tuned. probably 42lb ones since you're at 395hp now and 42lbs should be safe for 550hp +. when you get everything running right, you will up the jets. don't believe that you will stay at a 75 shot. i have some 37lb injectors for sale if you want to try them.
i just did a racetronix pump kit and it was real easy with the trap door method.

 

^ please PM me this "trap door method" and a price on the injectors if you think that will be enough injector since you already suggested 42lb ones.

Oh yeah.....and I WILL stick to the 75 shot, I'm not power greedy
