Going to run a LINK EMS stand alone ECU soon in my 95' Integra and was wondering if I have to get new injectors or is it only suggested? I don't know EVERYTHING about cars but I'm not a total retard either. I did a search and didn't find any questions like this. I'm currently just running about 6 PSI w/ a JRSC on a stock 95 GSR B18C1 motor. In the future I might plan to go to 9 PSI, IF I am able to use the stock injectors @6psi. Will is be possible to continue using them @9psi as well?

So far the setup is mostly stock with the basic I/H/E + 255lph fuel pump.

no...basically if you really wanted to use stock injectors you would need to raise the fuel pressure using an fmu. That would just defeat the purpose of a standalone. Get some dms 450cc's and a resistor box for like 50 bucks...those will be fine for 9 psi.

 

I doubt if you will want to keep the stock injectors at 9 psi. I'm in a similar situation. I have a 98 ITR with the jrsc. I just recently added a stepper pulley to get up around 8 psi. Next comes some sort of fuel management. My stock injectors are saturated 240cc. Most people here agreed that I need larger injectors. I'm thinking of using the 290cc from the 97+ prelude. The are saturated and will fit right in place without any other modification. I also figure that they are the cheapest option. Even with these I will have to run very high fuel pressure at times. That means more wear on my fuel pump and more strain on the lines. Since my car is not for track I don't push it to its limits very often, and never for any extended period. Because of this I'm willing to live with a little high fuel pressure. If you are planning on autocrossing or racing your car then I would recommend larger injectors in order to keep the fuel pressure down.
