I didn't ask if you asked somebody what it was. I asked if you actually poped the hood and checked the code on the block. It's easy to see.https://www.hondacivicforum.com/m_178568/tm.htm

PM3 would be a USDM D15B7, but that same head casting is used in other motors as well including the A6, and possibly some of the JDM motors but I couldn't tell you about those.

 

yeah and all the block says is d15b that is it that is where the confusion is coming in

 

Kk, it's a JDM (or at least non USDM) block then. There were several JDM D15B non-vtec variants made, from carbed to obd1. Yours is probably ODB1. I'm not sure what head it has on it, but I wouldn't be surprised if it was an A6/B7 head.

 

K well I am wanting to atleast get back the vtec so I was considering a mini me swap is there a head that you would recommend for the swap. and bout how much will it raise the compression

 

Z6. I wanna say 0.5-0.7:1.

 

K thanks for the info and sorry bout the confusion
