In a EG with a B16A SiR2 swap and no air conditioning what radiator can I get to give good enough cooling to autocross/drag regularly. I was looking at Koyo but someone had mentioned getting an integra radiator and new fans? I'm not going to drop 1k on an ARC I just want to get something that will efficiently cool the engine under hard driving cuz right now it's being cooled by the d16 radiator. Another question that I have wanted to know the answer to but just never asked is: is it better to run the crankcase vent to the intake tube, to a catch can and not to the intake tube, or finally to a catch can and then from the catch can to the intake tube? Not sure the benifits if any of the 3 different setups. Thanks.
