this might sound like a no brainer but im gonna ask it anyway. when i swapped in my first gen b16a into my 94 civic, i used my old dx injectors because i didnt want to add a resister box to use the injectors that came with the motor. I want to take out the dx injectors and put in ones for a del sol VTEC. is it worth the money? i can get a set of new ones for $300. my cars feels pretty slow to me and im kinda dissappointed with the results from the swap. if i switch injectors will it make a difference?
