i have an auto integra tryin to but a gsr longblock in what ecu do i need or what do i have to do to mine to make everything worj ok

 

My first thought is to use the ECU from the GS-R engine... You'll need that to control VTEC & secondaries.

But GS-R's don't have automatics, are you gonna keep yours? I don't know if there's any transmission functions that are controlled by the ECU??
