Well I finally got ahold of thy guy I bought the 91 cx hatch from and he told me the D15b block was a jdm Vtec series but the head was swap to make it an easier swap. Due to the vtec wiring it would have needed. The only code I can find on the head is a pm3-12 can any one give me an idea of what Im dealing with here. The cars starting to act kinda slughish and every once and awhile the idle gets real rough. Thanks for any advice or info

 

I know your head is from a D16A6. Its a non-vtec head. Ya the block is JDM if it only says D15B on it. The entire D15B engine makes 130hp (3 stage VTEC). The D16A6 makes 108hp. I have no idea what the head is like, or if it has any similarities to the D15B head (which is the same as the D16Z6 head). So if you did a mini-me D16Z6 swap you may have some real power.

 

K thanks man well I kinda new to the whole partial swap things what kinda car would i b most likely to find that head on
