is this motor jdm or usdm ? b16a i don't know how can you tell or where else can you look to see if its jdm or usdm?

 

B16A is JDM

 

okay so what is the difference between the b16a1 and the b16a. more power or they both the same?

 

JDM engines have like 10 more HP than USDM ones. Not really a big diff. But the B16s in the US are listed as 160HP and the JDM B16A is listed at 170HP

There is no such thing as a B16A1. JDM motors do not have a number after the letter. The only real difference between the B16s is OBD. The B16A SiRII/XSi is another difference compared to the 1st gen and EK4 B16As, and has higher compression pistons and puts out 10 more HP.

 

thank you . also my bad i could of sworn i seen a 1 after the A. so just more horse power. how can you tell what year the motor was built or what year the engine is?

 

I know on 1st gen B16As, it says PGM-FI on the intake manifold. You can also check what year the head was made, but there's no guarantee that it's the same head-block combo.
