DPFI to MPFI...What do I need!?

By YoTsi
- Wed Nov 21, 2012 9:30 pm #320547 ok im rockin a d15b2 bone stock DPFI and before anybody asks why i have a B2 its because in Finland if its not a 1.6 its a d15b2 or a d13 or d14, and yes those exist. simple. and my plan in the engine bay is to swap DPFI to MPFI and then a cam and boost. but i need to know exactly what parts i should use i dont have time to actually sit down and research and search through pages of crap and people not knowing what they are talking about and from what ive seen you guys are straight forward and to the point and thats what i need...PLZ HELP! :(

- Thu Nov 22, 2012 4:57 am #320605 A complete d16z6 manifold with throttle body/fuel rail and injectors. them you will need any mpfi engine harness or part of one and the you will need a mpfi ecu probably a d15b7 ecu i would guess. I'm sure there are other things. I'll get a buddy to chime in.

You have options as im sure your using an eg and i do know that across the pond you do have the dpfi pos crapola. and with the dpfi your car is also obd0......

Option A: Basic obd0 dpfi to mpfi swap
-injectors obd0 from either a mpfi d or b series.
-the plug harness from the car that you took the injectors from(injectors)
-May want to find a 4pin plug with pigtails for either side as it will be easier to unhook your harness for that.
-resister box with a good amount of pigtail
-id clip the tower plugs for the main harness as well just for the pins
-obd0 d series ecu crx d16a6 or other
-wireing
-d series intake manifold with associated stuff aka throttle body, fuel rail the good stuff lol
-and a obd0 d series mpfi distributor non dohc zc

Option B: a bit more involved but well worth it in my opinion Convert to obd1 and mpfi
-body harness from a obd1 civic with mpfi (as well as engine harness) may seem like alot but its the right way to do things
-obd1 intake manifold with the works injectors throttle body fuel rail
-obd1 distributor
-o2 sensor as the obd0 uses a 1 wire this will upgrade you to 4 wire
-and a obd1 d series ecu best to use a p06 but can use others im sure

both options do have their pluses and minuses but in my opinion option b will allow you for easier options with swaps in the future being obd1.

And here are some links to writeups the first one is the one i mainly have used in the past when doing some of the us spec dpfi civics (efs)
