I'm trying to take out my smoking built B20 motor and need to use the car still. I'm planning on purchasing a B16A longblock to replace the B20 to allow me to use the car while I fix the other motor. I was wondering what things are going to be different? Will the mounts line up with the B16 Block???? All sensors are the same??? I will have new dist., alt, and P30 ECU with the longblock. Any suggestions!!!

 

Mounts are the same. You'll need to wire up VTEC solenoid, pressure switch, and knock sensor.

 

OOOps, I forgot to explain that it was a VTEC head on a B20 block so I have the VTEC wiring there. Thaanks though...

 

Still need to wire up knock sensor

 

Do you know of any diagrams that will help me with that??? That will only be one wire that will have to be run to the ECU???

 

Yes, check the ECU thread on top for the OBD1 diagram. Look for KS pin.

 

u might be able to use the ecu u have in it now(since u had b20vtec) if it doesnt run like shet with a stock b16 (since i have no idea if it's chipped or standalone or stock mapped)
if youre using a chipped p28 it doesnt look for knock sensor so everything should be plug and play.
if your going to use a p30 or p72 then u have to wire up knock sensor.

 

Thanks so much. I think it is a stock ECU with a VAFC for tune help. I'm not to happy with this set-up and would rather tune with crome or neptune. I have to look and see what ECU is running in this car.
