I am planing on doing the mini me swap but I realize I need to do the intake swap as well. My question is some of the things needed to do the dpfi to mpfi switch are differnt than the mini me swap. I know i need
D16Z6 Cylinder Head (Including distributor cap, valve cover, plugs/wires, VTEC solenoid, etc)
D16Z6 or D16Y8 Head Gasket
P28 ECU
D16Z6 Timing Belt
Wire and plug for VTEC oil pressure switch
for mini me swap but what do I also need for intake swap and should i do one first or both at the same time

Any help will be greatly appreciated

You have to make it mpfi first.
-Take off your head, and manifold.
-Take out oil control jet.
- Clean the mating surfaces ( good luck if you were using the composite d15b2 gasket)
- switch the wires for mpfi( google that, alot of good write ups)
- use an obd0-obd1 jumper harness, then u can use your p28
- your jumper should include wires for vtec solenoid, vtec pressure switch, and 4 wire o2 sensor.
- make sure u take off the crank pulley too, cuz youll need to put the z6 belt.
- also will need to switch your dizzy harness plugs to whatever dizzy your using( like the d16z6 plugs)
- once youve wired everything, double check it.
- then use a mls head gasket, new dowel pins, install ur z6 head
- then put that new timing belt on
- put your new manifold( z6, a6,y8 whatever you chose)
- its easier if you put everything on the manifold before you put it in ur car( fuel rail injectors, throttle body, the sensors)
- use new intake gasket, bolt it on, connect all the hoses and sensors, connect the injectors.
- if using resistor box use obd0 injectors from an si
- plug your dizzy in( make sure you use vtec spark plug wires)
Make sure everythings plugged in
- add oil, add coolant, bleed the system
Then start your car.

Do the head and intake swap at the same time. A head swap is nothing more than changing a head gasket (pretty much).

Thanks for the fast reply and all the info greatly needed it. Now after reading this and the fact I bought another crx (1989 crx hf no motor/trans) I think I'm gonna put the d16z6/s40 into the Hf and do just the dpfi to mpfi on the Dx so heres what I know I need please let me know if there is something I missed
