if i'm swapping in a b16a2 into a 92 hatch do i have to change any of the wiring or do i just use a 0bd1 ecu and add the other wires for the vtec and knock sensor,ect

 

Get an odb2 wiring harness.

 

 

You will not have to run the VTEC wiring. All 92 Civics came pre wired for VTEC. You may have to add the knock wire (depends on the ECU your planning to use). It should all be plug and play with an OBDI ECU...

 

thanks for the info jv so i don't have to change anything on the obd2 motor like injectors or distrib to obd1 it's just plug and play with a obd1 ecu [exept for some wires] because kenji recommended just grabing a obd2 gs-r engine harness and using that with a obd2 ecu but i'll like to keep my car obd1....

 

Is this motor from a 99-00 Si?

 

yes it is

 

OK. That explains why he would say that. It would be wise to listen to kenji on this one...
