I will be using a weld on setup when the time comes for my 2jz and not sure if I will have my go to fab guy help with this or just get one of the kits available.
From Power House Racing:
"Anyone building a high horsepower/high boost 2JZGTE engine has to consider the effects of crankcase pressure at these levels. With the standard PCV valve (only 7mm) the engine simply is not able to remove pressure fast enough from the crankcase while under boost. The PHR Race Engine Breather Kit solves this problem, by increasing the venting area by over 200%. By removing crankcase pressure, you increase engine efficiency and therefore increase horsepower.
Anyone who has ever put together 12AN lines and fittings can tell you how costly something like this is to put together. This is not merely an “oil catch can” but rather a complete engine breathing system for big boost/big HP engines. Stock or mildly modified engines can also benefit from this setup, but only slightly. You must remove the OEM charcoal canister in order to install the breather tank on the passenger side of the engine bay"
And the Titan Motorsports offerings:
"An oil catch can collects the oil, moisture, and blow-by gas that causes carbon and sludge build-up in the intake system and engine, and helps to keep it clean even under the hardest driving conditions. This oil catch tank is also an excellent engine dress up item as well"
