Radium Dual Catch Can Kit (VTE Engine Vent) for 93-98 Supra (20-0387)
The Radium MK4 Supra catch cans function completely independent of each other and do NOT vent to atmosphere making them emissions and track legal. Three mounting brackets are included to accomodate all RHD and LHD models as well as big turbos, master cylinder brackets and even options for TRAC.
VTE = Vent to Engine.
Vehicle Fitment:
• 1993-1998 Toyota Supra MKIV

Full Description:
These catch cans vent-to-engine (VTE) permitting a true PCV system. The 2 catch cans function completely independent of each other and do NOT vent-to-atmosphere (VTA), thus are emissions and track legal. Closed loop systems remove the oil and sludge from the PCV gasses before it is routed to the engine to be burned. A closed loop system also promotes negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapors from entering the cabin.
PVC Vent Catch Can:
One catch can plumbs inline with the PCV (positive crankcase ventilation) valve and retains its factory function. When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV check valve closes and thus, this hose experiences no flow. Conversely, the PCV hose will experience metered vacuum when the engine is idling, steady state cruising, and decelerating. This would normally draw unwanted crankcase vapor, unspent fuel, and oil sludge into the intake manifold immediately after a high load run.
Crankcase Vent Catch Can:
The other catch can plumbs inline with the CCV (crankcase vent) port experiences atmospheric pressure at low loads. But when the engine is at high load (WOT), this hose will experience blow-by flow from the crankcase. This would normally lead to oil and sludge accumulation in the air filter intake pipe. Oil accumulation will occur in the intercooler which lowers the thermal efficiency properties of the heat exchanger and leads to decreased performance. The hose and fittings for the CCV catch can are -8AN.
Mounting Options:
Because of the many OEM component variations for this chassis, 3 different brackets are included for optimal mounting. These multiple locations provide a solution for all RHD and LHD vehicles including those using a large single turbo, the stock twin turbos, the updated brake master cylinder, and even early models that have rear brake TRAC. All brackets use factory holes and integrate perfectly with the surrounding components. No cutting, drilling or permanent modification to the vehicle is required.
Sealed System:
Because the Radium catch cans are pressure sealed, they are great for this boosted application so intake manifold connection is permitted. The hose and fittings for the PCV catch can are -6AN.
Includes:
• (2) Oil Catch Can with Integrated Condenser and Dipstick
• (2) Supra Specific Aluminum Mounting Brackets
• AN Adapter Fittings and Hose Ends
• Enough Hose for Custom Applications
• Stainless Steel Mounting Hardware
