-Our Evo 9 and X line has a few differences when it comes to proper oiling, which we will list out here

First and most important: We only recommend using the OEM oil drain pipe for all evo turbochargers. Do not use an aftermarket drain line such as the popular -10AN lines, they have a smaller internal diameter, and can cause issues with turbos leaking/smoking

For Oil feed, Our Journal Bearing 52 and 55mm, 57mm, Evo 9 and X turbos are designed to use the oem oil feed line location port.

The evo 9 62mm and 64mm Journal bearing turbo charger requires an oil feed line that runs to the oil Filter housing. We supply this feed line with every Evo 9 journal bearing 62mm and 64mm Turbocharger.

All Evo X Turbos will source oil from the existing oem feed port on the back of the block.

All Evo 9 and X Ball bearing turbochargers are designed to use a restricted oil feed line. Failure to do so can and will results in a leaking or failing turbocharger

We Provide a new braided oil feed line and appropriate size restrictor specific to the turbo you have ordered.

-We always recommend an oil that has a high Zinc and phosphorus content. Brad Penn is what we run in our shop cars and works great with our turbochargers. 

Other types such and AMSoil and Vavoline VR1 work great as well.

-We offer two specific ratings for wastegates on our evo line up.

22 and 25 psi ratings.

these ratings are minimum boost that your turbocharger will run.

the 22 psi gates are standard with all of our turbos and work great for the majority of customers. Great for upper 20's/low 30's boost pressure. 

If you have a built setup and planning on wanting all the boost, the 25 psi gate is what you want! either gate is available with any evo turbocgarger we offer.

We also sell these wastegates seperately

Wastegate Preload: 

We preload every wastegate to 3-4mm to tight, in some cases, when trying to  get the most out of your wastegate, you may have to add more preload. 

-This subject is commonly overlooked. Without a properly working PCV system, can cause lots of issues. Mainly causing the turbo to leak/smoke.

the OEM PCV system works good for the majority of low power, stock block evos, but weve found that after 450hp or so, the oem system doesnt stand up to the task of relieving crankcase pressure.

in our experience, a Fully vented catch can system, with atleast one -10AN size valve cover vent, and the PCV line, running to a well vented, and baffled catch can, works very well and keeping things under control.

If setup incorrectly or the PCV system is inadequate for the setup, this will cause the turbo to push oil/leak/smoke due to the excessive crankcase pressure hindering the turbo from properly draining.
