hows it going i am new to this forum, but a regular at my home forum(www.b15sentra.net), my question is what is the stock fuel pressure on my motor SR20de out of a 2001 sentra SE. second question is if i get 300cc injectors what PSI do i have to lower my fuel pressure to? where can i get a good fuel pressure regulator that will fit my SR20? and lastly, i plan on running a 75 shot of ZEX will a 190 LPH fuel pump be good enough. i need the nitrous to be safe, cause i already blew to motor up once on a 75 shot, but i need the juice, thanks in advance.
