Hey guys/gals a friend of mine bought a 98 civic with a b16a swap how can i tell what year si (obd?) did the engine belong I need to buy a b16a ecu but not sure what obd it needs. currently running ap72j (gsr ecu).

 

Bleh, I don't know much.

But um here's what I can tell you though.

I believe the 1st Generation B16A uses a Cable Clutch Tranny.

While the 2nd Generation B16A uses a Hydraulic Tranny.

 

that doesnt really help cause whoever swaped could of used either tranny. That ECU you just mentioned is a OBD2 ECU. So there you go, it's OBD2

 

Why are you using a P72 on a b16?? It doesn't have a dual intake. Just use a Si ecu.

 

but still engine itself could be obd1 originally and they could of changed dizzy and engine harness. But most likely its a obd2 also, much easier to do and more available

 

there should be a date stamped on the head in the lil circles itll say like p30 12 93 or somethin like that

 

Thanks for the info

 

What web sites would I be able to buy a p28 ecu did a search but no info.

Yes. One of the circles will say 96, or 98, or 00, etc corresponding with the year


If the VIN on the block matches the VIN on the head then it's original motor

You can also look up the year with the VIN. You can look up the month and day the car was made, what city it was made in, and more.....
