Supercharged pcv from turbo coupe

I think You could pop the plastic off the one onto the other or just plug the one smaller vac hole.

You plug the smaller port. I ran one of those on my 94GT with a Vortech. I wound up going dual breathers on the valve covers and ditching the PCV all together. I had to remove my strut tower as well because of the oil filler cap.

Why cant you use the stock pvc? Im putting a blower on my stuff right now....

That depends on how thing are setup as to if you can use stock stuff. If you use a positive displacement style supercharger like Kenne Bell then your MAF and TB will be before your making boost so your PCV system should work properly. If your using a centrifugal style supercharger with where boost is made before TB and piped in, then you have to change your PCV system up. You have to change your PCV setup because the tube from your oil fill cap to the TB will cause your crankcase to be pressurized by boost. That will blow your PCV valve out of your intake manifold if you get on it and may blow your dipstick out a few inches depending on how much boost you run. Its not a good thing.
