Do I need an oil restrictor for my turbo?
An oil restrictor is recommended for optimal performance with ball bearing turbochargers. Oil pressure of 40 – 45 psi at maximum engine speed is recommended to prevent damage to the turbocharger’s internals. Recommended oil feed is -3AN or -4AN line or hose/tubing with a similar ID.
What does a turbo restrictor do?
A turbo restrictor is essentially a tube fitted directly on the turbocharger’s air intake. The presence of the restrictor, which actually accelerates the gases flowing through it and directs the air flow to the center of the turbocharger’s compressor wheel, essentially increases the engine torque.
What size oil restrictor do I need?
Oil pressure entering a ball-bearing turbocharger needs to be between 40 psi and 45 psi at the maximum engine operating speed. For many common passenger vehicle engines, this generally translates into a restrictor with a minimum of 0.040″ diameter orifice upstream of the oil inlet on the turbocharger center section.
Can a turbo get too much oil?
If there is too much oil in the pan or if the turbocharger in your car is relatively lower, then oil can get through the seals and begin to blow out. This happens because the restrictor will starve the turbo of oil, which will cause all of the internals of the turbo (including all of the seals) to wear out.
How much engine oil pressure is too much?
A PSI over 80 is usually considered too high for the engine to properly be protected from damage. High oil pressure is an indicator that the oil is not able to properly pass through the bores and reach all parts of the engine effectively.
How much oil pressure should a turbo have?
Why does turbo spit oil?
If the oil level is too full there will be nowhere for the oil to flow, causing a build-up of oil pressure in the bearing housing. This will cause oil to leak from both the turbine and compressor ends. This can then force out oil from both the compressor end and turbine end giving the impression of a leak.
How much oil is too much oil in a car engine?
Most engine dipsticks have a range of acceptable oil level, spanning about a quart, or 20 percent in most cars. If you have significantly more oil than the top of the dipstick range, play it safe and let some out.
What size oil restrictor do I need for a turbocharger?
For many common passenger vehicle engines, this generally translates into a restrictor with a minimum of 0.040″ diameter orifice upstream of the oil inlet on the turbocharger center section. Again, it is imperative that the restrictor be sized according to the oil pressure characteristics of the engine to which the turbo is attached.

What kind of bearings do I need for a turbo?
Garrett has two types of bearing systems; traditional journal bearing; and ball bearing. The journal bearing system in a turbo functions very similarly to the rod or crank bearings in an engine. These bearings require enough oil pressure to keep the components separated by a hydrodynamic film.
