hey guy if i install an injector and fuel rail from a 92-96 prelude to my d16z6 would it make any difference

 

I'm not exactly sure how much of a difference there is in flow between the D16z6 (1.6L) and the 4th gen prelude (2.2L or 2.3L), although you'd assume there's some(especially with the 2.2L VTEC model), but you won't gain anything from increasing fuel flow (or the potential for it) unless you're also increasing air flow significantly (boost) and you'd probably need to upgrade the ignition as well to get any bang for your buck.

If you have them already, and they wire up and fit correctly, you could try it out and see what happens. I don't think you could hurt anything by doing one short drive (especially since I'd guess worse case scenario is that you'd run rich) but it's not worth it unless you've got other mods and/or you're having problems with your current injectors.
