I have a 1991 civic si and i did a B18 swap to it. The motor was out of a 1991 integra LS. I want to put a GSR head on it but i dont know how easy or hard it is going to be or if i have to change any of the electrical? If anyone has any knowledge on what to do please let me know.

 

should just bolt on... you may want to swap ecu's or get a tune to be able to effectively use the head

 

are you gonna use the vtec part of the head. if so then you are gonna need to ecu for the gsr

 

not to mention running an oil line to the vtec solenoid and wireing up the the solenoid...... its fairly involved... Make sure you know what yout doing before you start.

Berz out.

 

Give the bottom end a clean rebuild.
