For my engines class at school, my friend and I are putting a new engine into a 94 Civic CX. Our school has a few 16 valve d15s in storage, and we plan on using one as the CX’s new heart. The problem is that the motor we have is a non-obd d15. Although easier, we cannot use the obd1 head off the Civic as that is not an option. As of now, everything on the 8 valve motor seems to be transferring over to the 16 valve.

My friend and I got the obd1 distributor to bolt up the non-obd head (see pic). Will this work?



We plan on using the obd1 intake manifold even the port sizes don’t match (see picture).




The oil pressure sensor and this PVC thang transferred over perfectly (see pic).


The d15 we are using is a 16 valve. Will the ECU, which is intended for an 8 valve motor, work?

I'm basically asking if this would work

Thank in advance.

it will work, but not very well, if at all. just buy a p06 obd1 dx ecu. i'v seen them for cheap.

you need to convert to obd0 for that.

Why and why? Everything has now officially transferred over from the obd1 block to the obd0 motor.









With the obd1 intake manifold being used, how will this not work?

Just reuse the OBDI intake manifold, distributor, injectors, engine harness and ECU. You'll need to change the driver's side mount bracket to the 92-95 style and from there it will bolt in just like stock. The only wiring change you'll need to make is changing the regular 2 prong coolant temp sensor to the older prong female connectors which is located on the back of the block near the oil filter (OBDI sensor is located on the thermostat housing).
I just recently installed a 1990 D16A6 from a CRX Si into a 95 CX hatch, basically the same as what you are doing. Don't let anyone say it won't work or to change OBD and blah blah blah. Just reuse the OBDI parts and change the bracket and after that it's really not any different from the stock motor that came from the CX.

Thanks so much. As shown in the pics above, I did use the mount off the 5th gen motor on the 4th gen motor. I plan on blocking off the coolant temp sensor on the back of the block as I used the 5th gen thermo housing (that has the coolant temp sensor attached) as showin in pics above. I did this because I didn't know if the obd1 harness would reach the back of the block where the obd0 coolant temp sensor is located.

Everything will work fine. A d series is a d series, they all share common parts that are interchangable.

It started up and idled perfectly on the first try. Woot!

p05 ECU will work but its got weak maps and lower rev limit. I suggest DIY kit and converting it to P06 mode very easily. it all can be done for under $40 (check my sig or PM me)...

or find yourself the parts and get someone to burn you a program (maybe your electronics class has some EPROM burners that support 27C256 or 27256 EPROMs)

P06 program - 28 pin EPROM
28 pin socket
74hc373
j1 jumper wire
10k resistor

now to run the P06 you'll need a 4 wire 02 as well. also a small change within ECU.
if the board is a 11Fo-1500 then at Q30 - add C144 transistor
