Im swappin a B18a1 into a 89 CRX that had a jdm B16a in it. We pulled the blown b16. put the tranny and the clutch on the ls. put it back in. I dont seem to have all the wiring i need. plus the ls has like 15 vacuum lines that the b16 didnt have. need some tips. we have the zdyne b16 ecu. will it work on the ls? its a 91 b18a1. Thanks
 
ecu will not work..go to junkyard and get a 90-91 acura integra pr4. secondly make sure your distributor has white plugs instead of grey. refure to helms manual for vacume routing. as far as wiring you might have an egr on the b18 (you dont have to use this), you will now have 1 o2 sensor, no knock, no vtec, if some connectors are too short....make them longer. i think you have to lengthen the IACV and a few other assorted plugs
 
i have one pr4 ecu for $75 bucks shipped...OBD0....
