i have a 95 gsr with blox stage 1 cams, skunk2 pro series intake manifold, and was just wondering if i needed to get a adjustable fuel pressure regulator, 310cc injectors, and new fuel pump, i'm about to get a smsp header and 2.5" apexi dunk exhaust system with either a vibrant muffler or a rsx type s muffler. let me know if i need to spend the money on the fuel pressure regulator and injectors.

 

Skip the fuel pump, unless your current one is going bad on you. Your tuner will probably tell you to upgrade your injectors though. If you're gonna tune with those injectors, the FPR isn't necessary.

 

kewl, so i should just get the rc310 injectors then and forget about the FPR. after i install my cams, sometimes my car would have a hard start up, seems like it needs more fuel.

 

Did you do a valve adjustment after the cam install? Not doing a proper valve adjustment seems to be the culprit most of the times for not starting or hard starting.

 

Timing, cam and/or ignition can cause the car to be hard to start as well.

 

Tell me about it. My buddy calls me up one, day, says he can't get his car to run right after he installed some Blox A cams. I go over and his distributor is retarded all the way to the farthest point.

 

timing is correct, 16btdc, and i did valve adjustment as well.

 

also another question, should i get 2.5" exhaust system along with 2.5" carsound cat and 2.5" header or should i just stay with 2.25" exhaust, cat, and header.
