I went to autozone to get a new fuel pump since i did a swap with b16a3 from d16y7. and the fuel pumps for both motors were both the same serial number from autozone. i asked for an si pump but they said that the only fuel pump they had is for both these motor types. but that can't be true can it?

 

I'm pretty sure that both of the fuel pumps pump pretty much at the same rate. If you would have searched you would have found out that the stock fuel pumps support over 300whp
