I have a compleat b18b1 I was told it was out of a 96 but then was also told it was obd1. I thought everthing changed to obd2 in 96. How do I figure out which it is?

 

That can be tricky because it was a transitional year, so you could have a "late" 1995 or an "early" 1996.

The easiest way to tell is by looking at the injector clips or distributor plug.

Also, the OBD2 U.S. LS's will have a crank angle sensor. Look for a wiring loom running next to the timing belt cover on the back.

 

What do I look for on the injector clips if its obd1 dsm 450s will snap into them right? I think I have a set somewhere I will try that.

 

The OBD2 injector clips can be unclipped with your hand, whereas the OBD1 clips I use a pick tool to release the wire spring.

The OBD0 clips are like the OBD1 clips EXTERNALLY, but have different tabs molded to prevent complete connection of the wrong type of injectors.
