Hello everyone
apologies for the questions, it might be obvious for some but I’m pretty new.
managed to get my hands on a “B16A” motor, unfortunately it didn’t come with a distributor, I don’t know what model it’s out of. Iv been doing research all day but cannot seem to figure out if I need to get a obd-0 or obd- 1or 2. Any help is greatly appreciated
Some details:
block is stamped:
b16a

head is stamped:
pr3-4
9/2 0/6 1/1 0/1

 

ALL B16A VTEC distributors will bolt to the engine that you have pictured above... OBD-0, OBD-1, or OBD-2...

You are asking the wrong questions. First, what chassis do you intend to install the B16A in ? What type of engine management do you intend to use ? The OBD-1 and OBD-2 style distributors are functionally identical... the only difference is the plug style for the engine harness. The OBD-0 style distributor will function differently.

 

I plan on putting the vtec b16a in my non vtec 97 integra shell which is OBD-2A. I have the stock p75 ecu that i was planning on using before i got the b16a but I know now that might change. Any advice on which ecu i should use or if a change is needed? Thank you for the reply🙏

 

Since your engine wiring harness is set up OBD-2A, I would get a distributor from any of the following: '96-97 Del Sol DOHC VTEC, '99-00 Civic Si, '96-99 Integra GSR or ITR. Your P75 ECU has no provision for VTEC, so you cannot use it for the VTEC engine. The only "Plug-n-Play" ECU for your chassis and the B16A engine would be from the '96-97 Del Sol mentioned above.
