searched and looked up P/N but can't really find out, so.......95 del sol si with a D16Z6 swapped out for a B16A3 can i use same fuel pump? what about the Z6 injectors are those the same flow rate for a DOHC VTEC or different?

 

Yes you can use the same fuel pump.

And the flow rates not 100%, but the B16's are 190cc's I believe.
