Yes, the CTR uses the B18C block with different rods and pistons. Not sure if it uses a different crank though.
The two R heads are basically the same except the CTR intake cam is 3 degrees longer duration, exhaust cams are the same.
CTR pistons have a much higher dome. Putting CTR pistons in a B18C5 yields about 12:1 compression.

Yeah, you could do that, but it would be cheaper/easier to just buy the CTR engine if you are starting from scratch.
