Hello, I
am currently building a b16a for boost. There are two holes in the back of the block a threaded hole and a smooth hole, I am wondering if I just get a frost plug for the smooth hole and a threaded plug for the threaded hole will I build to much Positive crankcase pressure?
You'll need something like this, if you want to run a CC setup. Note, you will need to remove another threaded fitting on the other side of the oil filter location
