i have a 00 civic si b16a2 block and tranny paired with a 89 crx b16a head ive been building, i just got some b20b injectors today, cleaned them up all new seals.. then i dropped one and it broke, my scrap yard doesnt have anymore b20b injectors are the f22b injectors identical? would they be compatible with my engine?

another thing ive been wondering is i have a 97 civic dx that has been swapped with the b16 and the evap purge valve isnt there, i dont have a connector for the canister, it not there... also why does my b16a2 harness only have one o2 sensor plug?? im so lost. any help would be great i dont want to order new injectors, im fine with used ones i got a whole rig i through together in my basement with a 12v power supply and i used carb cleaner to clear them out!
