'89 EF motor options
I just came into an '89 Civic hatchback with a D16A6 in it (non VTEC) and am wondering about my options.
Is there a Type R head that'll fit on my motor? Or do I have to order a new mill online?
Any help greatly appreciated.

Re: '89 EF motor options
no type r. you could put a d16z6 head or a d16y8 both are vtec heads sohc. othe rthen that youll have to swap a full bseries for anytype r head. or u could do a k series swap or a h22 swap
Re: '89 EF motor options
even better. you could buy my d16z6 head, do a mini-me swap, and swap to MPFI / OBD1 i got the parts too. evreyting but the mainifold. then u'd have the closest thing to a EG motor in a EF.
Re: '89 EF motor options
What all would I need to buy to make the conversion work?
Re: '89 EF motor options
well i can assume yours is DPFI? 2 injectors vs 4. u cant do **** with that setup. not even chip it. i would convert to MPFI first. i cant think of a ECU that isint MPFI and VTEC. obd0 or 1 dosent matter as both famalys have, or ecu's that can be chiped to be, vtec ECU's.
actualy i just read the post and u said u have a A6 motor? in a hatch? must be the SI hatch. if thats true your allready MPFI. u lucked out bro lol.
the easiest would be staying OBD0 and getting a PS9 ECU. thats a automatic 90-91 EX and was the only ecu to run the A6 engine as a automatic for the sedans. there are porgrams u can use (chip the ecu) to make the auto output (one wire vtec) into a VTEC output. this wont be a stock program though so u may not pass your emmissions test. OBD1 would need a P28 ecu (92-95 EX/SI) but as there the single most popular ecu, they can be tricky to get / expensive. i got some P06 witch is OBD1 92-95 DX/LX and can be chiped and have the VTEC componets added to make a P28. I recomend going OBD1 as there are FAR more options of tuning especaly with a mini-me swap.
if u wanted OBD1 u need 3 main parts. OBD1 ECU, Distributor, and 4 wire O2 sensor. First the ECU is diffrent as it's is 16bit vs 8 bit. better resolution. like going from standard to HD tv. better control and mesuring. Second is because of the first the Distributor has the 3 sensors needed for the PGMFI system. these sensors have double the pulses on OBD1 vs OBD0. and lastly u need a 4 wire O2 as the ECU has a heater output for the heated O2. this is needed for proper poweroutput and on that old of a car it couldent hurt to change it anyway.
i can sell you the head with the obd1 distributor allready atachehed. i even have the OBD1-OBD0 harness and the Distributor Harness as there plugs are diffrent. what i DONT have is the manifold (your MPFI dont worry about it) and the 02 sensor.
if u want to read further or re-read what i just typed out go to PGMFI.org

Re: '89 EF motor options
I hate to steal this thread but I have the same question but I have a d15b motor in an 89 civic dx.I also was thinking of the mini me swap,do I have to do the same but change to mpfi?What is the horsepower and torque rating (roughly) on a mini me swap?
