i just have some quick questions about my new purchase, hopefully you guys can answer them! i just bought a mint 91 dx hatch yesterday and like everyone else, i want to do a swap. i would really like to do a full b series swap but i am also considering doing a mini me swap. with the mini me swap and or b series swap, do i have to convert from obd0 to obd1? i am most likely going to be doing a mini me swap just because i dont have the money to do a full b series swap. but i want to swap the intake mani that is on it now(stock) as the first step of the swap. if i have to convert to obd1 then do i have to do it before i swap the intake mani? i appreciate any help, hopefully i can post some pics of my new ride soon. THNX

 

you can do a manifold swap and still run obd0.you will need a 88-91 mpfi dizzy and a pm6.google dx to zc.you can also do a b series swap without going to mpfi.but if you do a minime,you should definatly go to a p28 obd1 ecu and dizzy. http://hybrid.honda-perf.org/tech/4gdxtozc.html

 

if you ever plan on having it dyno tuned, go obd1.

 

what is a mpfi dizzy and pm6? sorry im pretty new to these older hondas but love them, also new to honda slang so you will have to give to me in actual full names of parts. im still a noob thanks agian

 

mpfi = multiport fuel injection (d16a6 intake mani/dizzy/etc from 88-91 si's)

and the pm6 is the si ecu

 

is the mpfi a single part or is it an entire setup? also will a pm6 be completely compatible without having to change anything else to hook it up and what will it chenge? im really just trying to get a little more power with out losing gas milage and buying a bunch of aftermarket stuff. thanks
