OPR V2 Turbo Oil Pressure Regulator
$159.94USD (Excl. Sales Tax)
Turbosmart’s ALL NEW from 2022 OPR V2 Turbocharger Oil Pressure Regulator provides rock solid oil pressure for your turbocharger from a simple, inline return-less regulator and includes a built in 44 Micron Stainless Steel Mesh Oil Filter.
The Turbosmart OPR V2 is a World First Return-Less Regulator which achieves target oil pressure through Turbosmart’s Patent Pending flow control strategy, to delivery a laminar flow of oil to your turbocharger, no matter the base engine oil pressure or temperature. Suitable for all known engine oils, the OPR V2 from Turbosmart will down regulate any oil pressure to ensure the critical balances inside your turbocharger (Exhaust Drive, Back & Charge Pressures) aren’t compromised by over-pressurised engine oil causing consumption of oil and smoking.
No more trial and error with with restrictors and orifice sizes, or needing to fit and plumb a reuturn line to regulate your turbocharger oil pressure, the OPR V2 from Turbosmart is a simple return-less and inline fitment with a built-in 44 Micron Oil Filter. The Built-In Stainless Steel Mesh Oil Filter is serviceable and replaceable and is another layer of defence from debris in your engine oil damaging your turbocharger.

OPR Turbocharger Oil Pressure Regulator
1 x1/6 NPT Blanking Plug
The Turbosmart OPR is a regulator of oil pressure designed for turbochargers. Turbochargers generally require engine oil, supplied at pressure from the engine. Turbochargers have a target window of oil pressure to operate efficiently and safely. Engines typically have an oil pump to supply many parts of the engine, including the turbocharger, however these pumps generally increase pressure and engine RPM’s increase. This is exaggerated on modified; high-performance and race engines where high base & overall engine oil pressure is achieved and desired by other areas of the engine such as crankshafts and camshafts. The role of the OPR is to down-regulate the supply of oil to the turbocharger to better suit it’s needs.
What happens when the Pressure is too high to the turbocharger?
Turbochargers are designed with a balance in mind and the oil pressure is considered with this. Within the centre cartridge of the turbocharger there are seals that separate the engine oil, bearings and shafts with both the exhaust gas and intake charge. These seals are not rubber like you might think, rather a gas-ring more like what is found on a piston. The profile of these seals are designed around an assumption of oil pressure and when over this pressure, the oil can compromise the seals. The most common symptom of this is when and a engine smokes excessively which is caused by engine oil passing the seal and entering the exhaust gas.
What is the OPR V2 about and how is it different?
The OPR V2 Oil Pressure Regulator is an inline, return-less design which hugely simplifies installation. The same ability to regulate oil pressure is achieved through a Patent Pending oil control strategy within the unit and it is no longer necessary to install a return line like the original OPRt40 in order to achieve the target oil pressure. The OPR V2 also including a built-in Stainless Steel 44 Micron Mesh Filter to help safeguard your turbocharger. Another improvement in the new OPR V2 means a fitting kit is no longer required as the units are machines with Male -4AN inlet & outlet, which is yet another part that is no longer needed, increasing the value and easing installation. The OPR V2 from Turbosmart will fit inline to your turbocharger just like a traditional oil filter & will do so much more!
What is the pressure it achieves?
The OPR V2 will achieve 40 psi +/- 10% dependant on a number of variables, mostly concerned with the grade of engine oil used and its operating temperature. The great news is the entire window of oil pressure the OPR is spec’d to product is well within the design parameters of all known Ball-Bearing Turbochargers and as many journal bearing turbochargers we have found supporting documentation on. We cannot guarantee this will suit every turbocharger ever produced as the data to support that claim is simply not available – However if you have any doubts, you can check with the manufacturer of yours and you will see, this is almost certainly suitable.
What is Laminar Flow Design Mean?
This refers to the quality of oil flowing out of the OPR V2 Oil Pressure regulator. If you are concerned the oil is bearing aerated of the quality of the flow is compromised as a by product of the regulation, don’t be. It’s not and we have designed it not to impact the quality of flow & validated this at feed pressure several times higher than any engine can produce.
Why is this better than a typical restrictor?
There are a few reasons. The first is these regulators are dynamic whereas a restrictor is static. A restrictor can modulate oil flow, it simply reduces it with a hope of achieving the required pressure and cannot compensate for oil temperature, oil grade or the increase in pressure as a result of engines operating at higher RPM’s or with high-performance (hi pressure) oils pumps. The OPR on the other hand can & does. Secondaly, Aftermarket turbocharger installs mean there is no restrictor off the shelf that suits your variables without trial and error. You could guess lucky, but it would be a guess & is still limited by the grade, temperature and increase in pressure due to RPM’s and pump changes. The OPR V2 handles all this for you, installing no different to an inline oil filter.
