OK... A little background,
I have a 89 civic DX HB.
I purchased a B18A1, w/trans: 91 integra axles, ECU, and motor mounts. I've converted the harnes tp MPFI

I found out my B18A1 is toast... (broken motor mount on block)

So my good friend gave me 2 B18B1's that appear to be newer... the valve cover is inset in the middle...

Problem is both of these are missing the distributor, one's god a bent valve, and the other has a bend rod... But between the two I can get a good, working B18B1.

I believe these 2 B18b1's to be OBD2a, how can I tell? The valve cover is not flat, but rather inset in teh middle...

So the question is this, assuming the two new B18b1's are OBD2a, can i take the two and make one complete motor, and use my B18A1's distributor, injectors, resistor box and run it as a OBD0 B18B1? I'll eventually buy a obd2 distributor, ECU, and wiring conversion as I have another stock harness...

does this make sence?

Take the two dead (what i think are OBD2a) B18B1's and use the B18A1 Dizzy, injectors, resistor box and harness and run a B18B1 in OBD0 for now?

How do i tell a motor is OBD1 or OBD2

Please advise, Help is greatly appreciated!

 

its not that bad
there the same basic block change all of the hardware from b18a to b18b
injectors, dist, wiring, think that it and put it on ur b18b same thing just newer

 

yeah b18b are obd1 and 2 doewnt matter unless ur changing from 0 to 1 or 2 in ur car

YES!

obd 2 blocks usually have vin plates on them. they also have a crankshaft fluctuation sensor, and flat plain valve cover
