Test your GTR twin turbo the correct way and keep the motor running healthy!
Design for all aftermarket intake using a 3" pipe diameter. These twin billet caps will be installed inside the 3" silicon adapter right at the turbo inlet or any 3" flexible connection on the intake depending on what intake you are running.
Pressurizing the system will allow you to run peak boost your motor was tuned for ensure you are putting all the power down without any leaks. A boost leak will cause the compressor wheels to over-spin to compensate for lost pressure. Eventually this puts a lot of strain on the turbos and they start to develop shaft play from running hot and poor oiling.
This boost leak tester kit will include rubber caps for the PCV system. This is critical to performing the boost leak test correctly! Otherwise the crank case will be pressurized with compressed air and this can put load on the camshaft and crank seals. Cap off the crankcase and leave the oil cap OFF during testing.

1. remove intake pipe and expose the silicon adapter on the turbo inlet, from each side
2. Insert the boost leak tester end caps into the silicon inlets
3. disconnect the PCV line from each side of the valve covers and plug the hose with the provided plugs and zip tie.
4. remove the oil cap to prevent accidental crank case pressurization
5. Fill the system with a compressor. Start with low pressure such as 5psi. Listen for leaks, fix leaks and repeat to catch the next leak. Largest leaks are found first.
* good practice to disconnect the diverter valve "blow off valves" return lines as shown in the pic. This will test the diaphragm of the diverter valve. It should not leak air on the return side when boost leak testing.
