will i be able to put a usdm B16 head on a jdm B16 block? The reason i asked is because i bought a jdm B16 bare block from my friend and i'd like to make it usdm spec. Or is this a stupid idea. Your comments and advices are welcome. Thanks.

 

The heads are swappable. Making your engine USDM spec will result in a loss of power. The usdm B16A pistons have a lower compression ratio. The JDM B16A makes 10 hp more than the USDM B16A.

 

well i'm planning on putting in ctr pistons (std)....would that bump up the compression?

Well using the C-Speed Racing calculator, the resultant CR would be 10.8:1. That sounds kind of low to me.

 

well obviously i'd have to go with the jdm head....thanks for your help

 

I'm running a JBD B16a block w/ a USDM Del Sol head and OS CTR pistons. 10.85:1 CR w/ OEM head gasket. You need not find a JDM head.
