ok i have a b20b in my 98 4 door ls its got a walboro 255 fuel pump, rc injectors, headers, obd2 to obd1 ecu harness, with a chipped p75 ecu all bolted to a gsr tranny.

I now have a fresh ass GSR head out of a 2000 gsr.

What steps do i need to take to put that head on my car and make it reliable?

I know i have to get the oil lines but what else should i do? or would it be easier to just swap the whole gsr into my car



GSR VS B20B
