Hey guys i recently purchased a 89 crx that has b20b swap in it ...the motor is blown and now im wondering if i can use my b18b1 obd2 motor out of a 99 integra ...
My crx is running a pr4 l11 ecu (obd1 i believe) and the dizzy connected to the b20b is obd1....so would i be able to just conect the dizzy intake manifold and injecters to the b18b1 in order for it to run correctly?

 

Also i just took of manifold off on b20 it was stamped p75 isnt that obd2. Do i not need to switch the obd2 manifold but just the dizzy and injecters

 

OBD1 and OBD2 distributors share the same internal electronics. If it bolts up and plugs in, then the ECU is going to be happy.

Injectors are not OBD specific. If the injector is the proper flow rate for the ECU then you can use any style of injector that fits your intake manifold.

 

Oh ok thanks for the quick response and the info. I was just being to worried haha
