hello, i am putting a d15 in my car that had a b16 in it. i have the whole car that the d15 came from...what parts from it do i need electrical wise? i know i need computer, engine harness ect, but do i have to do any converting of wires? thanks
 
um no.


you'll need to convert from mpfi to dpfi... which is retarded...
convert the d15 to mpfi, and save yourself a lot of headache, and get some power gain out of it for next to nothing cost-wise.
 
thanks thats what i needed to know. the cars already set up for mpfi so can i just use a intake and ecu from a si crx or what? the thing is i already have a running dx thats too rusty to fix, so i was gonna throw the engine in my si for a daily driver. the b16 is goin into my other si. how hard is it to go back to dpfi if i have everything anyways? thanks this is a big help
 
basically, you'll have to do the opposite of an mpfi swap.

there's diagrams in the referce section and pinout thread
