94 b18b header on a 93 gsr

my friend went ahead with a turbo install on his 94 ls… he gave me his dc 421 header and i wanted to see if it will fit my 93 gsr with out any problems such as ( fitment,o2 sensor)


it should fit because its a b series motor… im about to install headers from the new gsr’s… as for the 02 sensor not quite sure
