i have a 1993 del sol si, sohc vtech, i just purchased nos (dry system 25 shot) will it hurt if i put the 450 injectors on my car, somebody said i should do that because of the fuel. or should i put a fuel pressure regulator on

 

It won't help you with Nos

 

im running a dry 55 shot and i have stock injectors, i do have a fuel rail and a aem FPR set to 43 psi (at wot) when i spray.

 

should i go ahead and buy the injectors, the guy is selling for 75.00 they are in good condition, it com with a unit to hook them up, is it hard to hook them up, i am new to all this ****.

 

75 is too much, i got mine for 40, and they are simple to install
