Whats up fellas!! I recently lost my b18a1 after unknowingly loseing oil pressure (hit a bump that knocked my drainplug loose) and throwing a rod bearing. Since I had to pull it out to fix properly I decided to throw in a b20b with p75 head.

I swapped my obdo dizzy and ls intake over. Found out that the oil catch can/pcv valve was not used on the b20b. Instead pcv plugs into valve cover.

So far so good all runs extremely well. Started up first turn. Before I made the swap I always had barametric pressure sensor code thrown but was getting 36+mpg for the daily grind so I didnt care. That code is still there but now I get the cps code. Checked all resistance with dmm and all reads within parameters.

Car runs like a champ lol Would still like to get this solved so anyone with some input plz feel free to chime in!

Distributor, ecu, loose wire at your jumper harness or distrib plugs. Start trouble shooting wiring, continuity check everything to make sure there are no breaks in the wiring then report back. The dreaded code 9 happened to me on my H swap and it turned out to be the jumper harness wires were wrong (not your case since it worked before) but still just as annoying. Good luck.
