Greddy ITB Kit with Oil Catch can?
 

I am planning on purchasing a Greddy ITB kit with velocity stacks in the near future. I am currently running Radium dual oil catch cans on my 86. I know if with the velocity stacks, I no longer be able to run the CCV side for my catch can. Does anyone know if I will still be able to run the PCV side with the ITB kit?

When installing a Greddy ITB kit with velocity stacks, consider the necessary modifications to the crankcase ventilation system (PCV) and catch can setup. Making the PCV system work in line with the ITB setup may call for professional help like making another breather system or using a PCV plate. Also, make sure that the catch can arrangement is compatible with the modified PCV system. Proper tuning is important for optimal engine performance when using ITBs.

I'd personally just dump the PCV to whichever can makes sense routing wise and get the filter add-on for the can so it can just be vented to atmosphere. This is more or less equivalent to the setup I run on my K24 BRZ.

The fitting is "Radium 20-0050 10AN ORB Fitting to Air Filter"
