b16a in rex
can i swap out the block for a b18c and use the b16 trany and head?

sorry if its a stupid question .. just curious

 

yes

 

all b-series parts, so yeah.

 

Does anyone know how the B18C1 bottom end with the B16A head run in the EF civic's?

 

would the compression be the same as a gsr or is the head even smaller then a gsr head??

 

the compression will go up as the B16 has a different combustion chamber layout. it will run well, hog the runners on the B16 head while it is off. in fact, get the head fully ported professionally with a flow bench, should see some nice gains.
