High rpm, high boost or track use normally justify upgrading the pump or billet gears, especially on engines known for oil pump weakness.
Do I need an oil restrictor or head drain?
Some DOHC turbo engines benefit from a restrictor and head drain to control oil pooling at high rpm. Whether you need one depends on your build.
What size oil restrictor should I choose for my RB engine?
The choice of oil restrictor size depends on your engine's specific needs and intended use. For moderate restriction, the 1.2mm restrictor is suitable for street applications. The 1.5mm restrictor provides increased restriction for higher performance setups, especially in racing conditions. If you have custom requirements, the blank option allows for tailored applications.
How do I install the RB oil restrictor?
Installation of the RB oil restrictor is straightforward. Ensure the engine is cool and clean the area where the restrictor will be fitted. Remove the existing oil gallery plug, if applicable, and replace it with the chosen restrictor size. Ensure it is seated properly and secure it to prevent any oil leaks.
Will using an oil restrictor affect my engine's oil pressure?
Yes, using an oil restrictor will affect oil pressure by regulating the flow of oil to the cylinder head. This helps maintain optimal pressure and lubrication, especially in high-performance applications. It's crucial to monitor oil pressure after installation to ensure it remains within the desired range for your specific setup.
Can I use the RB oil restrictor with aftermarket oil pumps?
Yes, the RB oil restrictor can be used with aftermarket oil pumps, but it's essential to ensure compatibility. Aftermarket pumps may have different flow characteristics, so it's advisable to monitor oil pressure and flow after installation to confirm that the restrictor is providing the desired performance without causing oil starvation.
Do I need to modify my engine when installing the RB oil restrictor?
Generally, no significant modifications are required when installing the RB oil restrictor. However, ensure that the engine block and oil passages are clean and free from debris. Depending on your engine's configuration and the restrictor size chosen, some minor adjustments may be necessary for optimal fitment and performance.
