I recently sold my '97 EX and purchased a '88 CRX Si that had a good start but needed finishing. The previous owner said that he had the head milled 0.044" I have been trying to figure the compression ratio using this, but I don't know the head volume. Does anyone know what C.R. the machined D16A6 head will give me. I need to know before I put any forced induction to the car. If it's too high, I guess I'll be building a ZC for the turbo. Something I was going to do anyway but after I blew up the stock engine.

 

stock d16a6 head has 38 cc combustion chamber

 

thank you kind sir

 

But the head has been milled, so it's not 38 anymore...
