I have done some research and just want clarification that I am on the right start. I currently own a 1990 civic standard which is a 4 speed and looking to do my first swap.

Looking to either put a d16z6 or y8 into my civic.

Parts required:
Engine:d16z6 or y8
ECU:p28
Distributor: from the motor i choose to go with
Engine wiring harness: whichever engine I decide to go with, either the Z6 or y8
Extra Wiring:a conversion harness for obd0 to obd1 which can be purchased from rywire OR i could actually rewire it on my own
Extra Wiring: a conversion harness for dpfi to mpfi which can be purchased from rywire OR i could actually rewire it on my own
O2 Sensor:4 Wire
D-series header
Motor Mounts: Hasport or reuse the mounts which come on the new engine. I will have to swap the stock driver side mount from my current engine onto the z6 for it to line up correctly.

Parts which should be replaced:
Fuel filter
Head bolts
Timing Belt
Water pump
Spark Plugs
Distributor cap and rotor
valve cover gasket
Radiator and hoses
hondata intake manifold gasket
upgraded intake manifold

Tranny:
1990-1991 si tranny OR
1992-2000 tranny with a cable to hydro clutch kit from Hasports
a complete harness from rywire.com.
Shift Linkage:depends on which tranny
Clutch and pressure plate and these parts depend on which transmission i decide to go with
Axles: which?
Flywheel: for the tranny? engine? or my car?

Engine management: VAFC? or what

Am I on the right track? what parts am i missing? what parts should I add?

What I am unsure of....................
no clue about which axles to use
no clue on if i need the resistor box on not for dpfi to mpfi
Distributor? just match the engine
Flywheel: for the tranny? engine? or my car?

all help is welcomed. Thanks!

 

Looks like youre on the right track and have done plenty of research. I would get some ARP head studs instead of head bolts, you can use the stock axles the car came with, i would go with a resistor box just to be safe but there is a way to eliminate it on newer model civics so it might work for your setup, if youre running a single cam vtec head you need single cam vtec distributor. I do believe the flywheel and clutch should be matched for your engine but i could be wrong on that. good luck with the swap

 

As far as engine management, all you need is a P28. No need for the VAFC. Flywheel can be any you choose but it has to be the same as the year trans. 90-91 is different than 88's or the CRX trans. Engine harness, i suggest you modify the current one to accept the MPFI. Its not hard, just read through the write ups.

Inside the car you are moving wires from C1 and C2to B10 and B12. the C1-C2 are now empty and you will run those to the Dizzy for your Cam angle Sensor.

The portion of the engine bay requires wiring up the 4 injectors from the ECU. A1 A3 A5 A7. ALso the Resistor box will help if you are running low impedance injectors.

Once you have done all that you can get a Rywire OBD0-OBD1 Jumper harness and you can run a P28 ECU. Wire up your Vtec and your 4 Wire and you are done!

Good luck!

 

No engine management.

Use stock axles.

So I should rewire the harness's myself and do the conversion harness for dpfi to mpfi.

Purchase the conversion harness for obd0 to obd1 which can be purchased from rywire

Get the resistor box.

 

you got it.
