im getting a 97 ex civic 2 door coupe
well it has a d16y8 motor in it, but the motor has a rod knocking real bad
so im just goin to replace the whole motor

I have a d15z1 obd1 motor im going to use.

WHat do I need to do to get it running.
Someone said ill have to swap the oil pumps out and also some people have said i will have to repin the harness and other things.
Can anyone tell me a list of things I need to do to get it in there and running.

Thanks.

 

Doesn't the motor have to be from the same year or newer to be legal?

(Just curious)

 

Hell if I know. I just need to get the motor running so I can have a car to drive.
I need to know what I need to do to do the swap right and have it running.
Thanks

 

Just use the D15Z1 block, and keep everything else form the D16Y8. If you do that, all you should need is another headgasket.

 

well How long will that take to swap everything over to the d15z1? CUs i gotta get this done within one day.

 

Doing a mini-me shouldn't take that much longer that taking one engine out and putting another.

The only EXTRA steps are unbolting the D16Y8 head off the original block, then bolting the D16Y8 head, headstuds, and head gasket on the D15Z1 block.

A Y8 head and Z1 block should have matching timing, so unlike a D15/Z6 head mini-me, that is a headache you don't need to worry about.

Beside's it'll be worth it, if you put that whole D15Z1, you have 90 HP moving your heavy EJ6, if you use your D16Y8 head on the D15Z1 block, you should be around the stock rating of 127-ish. Give or take because compression change, and displacement change.

Also, if you use your head, you have ZERO wiring changes needed.

 

sweeet sounds good. SO i dont have to change the oil pump out or anything.
ANd what kind of headgasgate do i need? Also what kind of studs or anything do i need?
and how long should everything take to do includiing pullin out the old motor n stuff.

 

Changing the pump is something you do for peace of mind, when putting in another engine. I replaced my first D16Z6 in my coupe with another D16Z6 block, using the same head, and the oil pump with the ":new" block. A month later I got ECU
code 22: VTEC oil pressure, then a week later The pump went out, engine almost caught fire, so instead of buying a 3rd SOHC, I just went B16.... If the D15 has low miles, go ahead, if not, use your D16 oil pump, if it's too risky, just get a new one.

A new D16Y8 headgasket

Reuse your D16Y8 headstuds

I can't tell you how long, too many factors....

 

Hey bro this should help you in your Mini-Me venture ...
