i got a integra for a friend what do i need to swap to get the b16 to work in a 90 crx?
the car already had a d16 in it.

 

i never say this,but you couldnt search? its been done about a billion times,,same things ..you'll need a b-series into 88-91 crx mount kit,,shift linkage(either cut and reweled 90-93 integra or aftermarket linkage),90 integra rear mount bracket,make a dent for alternator clearance,,add the 4 wires and ground for vtec and pin them into the ecu clips,,if you gotta dx you have to convert to multi point fuel injection..search for more info
