See, i have a d15b2 and i know i should be able to switch my Throttle body fuel injection into a multiport fuel injection by removing the intake and throttlebody out and installing the multiported intake manifold from a D-series motor and it should match up, but i want other opinions, so i can be more sure.

 

Yes you can do a dpfi to mpfi swap do a search there is a million write ups on this topic. also if you plan on going b series or anythign else u are going to need to convert to mpfi. its worth it
