RB25 catch can setup help

[bkos90]

I SEARCHED and found a lot of threads on how to connect the catch can. My catch can only has 2 ports on top and a drain on the bottom. I saw that a lot of people have theirs connected in a different way. So i wanted to know which is the RIGHT way to do it.
Setup 1 or 2?

I use Setup #1 and have no complaints.

setup 1 is best as it will put vac on the crankcase where as setup 2 will just vta...
i run setup 2 but mainly due to space constraints...id rather setup 1.

I think it would work. Here is a good thread about it

hahahaha I thought we created the thread to end all catch can threads! I'd recommend "Setup 1" if you can do it. Sometimes the plumbing clutters the engine bay. That's why my setup is in line with "Setup 2".

I run setup 1. I always had an oil seepage past the crank seal until I changed to setup 1 from setup 2.
