lower the compression? you mean raise i think
I think what he means is that the B18C1 head has a smaller combustion chamber then the B16a, therefore using the B16A head on the B18C1 block will slightly lower compression.
B16A head + B18C1 block = poor man's type R <---search for this.
If keeping the B18C1 head, I don't know if the Type R IM will bolt up to it, but the Skunk2 IM are similar and will bolt up. The point of using the B16 head is that it flows better then the B18C1 head which means more HP, the slight drop in compression won't matter as much, since its static compression, as how the head flows. I believe the B16 and Type R heads are the same casting.
No you cant the B16 and type r heads have a different intake manifold bolt pattern than the B18C1. The B16 head (any year) has a smaller combustion chamber than the B18C so it will up the crompression. I dont think it is worth the effort to do this head swap. I would put in swap type r cams or some stage 2 cams insted.You can use a b16 or itr intake mani which from my understanding is better than the gsr
