So I had a D16Y8 1997 Civic engine that blew out I just bought me a jdm d15b does the old engine harness work on the new motor I just got and what else do I need to make it work I'm new to the Honda world so I don't really know what I got myself into any help will be gladly appreciate it

 

Should be able to use old harness, only thing is I believe you wont have vtec

 

My civic has a d15b with no wiring hacked up at all, only difference is its running the y8 head on it. Still using the d16y8 ecu and wiring and the car runs well. It has actually outrun a similarly aged d16y8 but it was a driver's race.

 

The d15b is non vtec I also heard another pages the ECU needs to be replaced????

 

Nothing you've said tells me that this is an obd1 or an obd2 d15b.

 

How how would I know if it's a obd1 or an obd2????

?????

Edit: I have a 1999 d15b non vtec does my old harness and ecu form my d16y8 on the new motor

 

post pictures of the motor. one way to tell if the d15b is obd1 or 2 is where the dip stick is located at. if it is in the middle of the exhaust manifold, it is obd1. if it is near the cam shaft its obd2.

swap your intake manifold on the motor. but the ecu would need to be changed. find a p2e ecu from a dx/lx/cx

I'd like to see this. Is this true across 1992-2000 then

 

How do you know its a 99 D15B? Please post the head code.

In essence, you're swapping your D16Y8 for a D16Y7.
