As with EVERYTHING Supra please try and understand the stock system before you try to reengineer it into a problem.

Thats my setup right there. I learned the hardway though... don't run just a filter on the catch can. You need to run a line to the intake of the turbo and put it where the filter is.
You HAVE TO HAVE VACUUM ON THE VALVE COVERS or kiss your front, rear, and cam seals goodbye!
Yea I spent a good month trying to track down why I had no venting for crankcase. Finally got it figured out after doing the valve cover gasket like 4 times after it blew past the gasket in the same spot every time. Needless to say get that fixed then the coolent hoses started going. Damn people letting cars set. Worst of all it took the headgasket with it on the highway.

Yep, my cute little filters are in the trash. Once my motor gets back from the shop, I'll be putting on my new catch can.
