I have a d15b2...I was wondering what is the difference between swapping out the DPFI to MPFI versus putting on an SI head(d16a6)which I will have to do MPFI anyways. Will both ways put out the same power or is one stronger than the other. I don't know why I thought of this but I did cuz I'm doing a motor swap soon anyways, but for now I'm just gonna put MPFI on it. THanks
