    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
