Vehicle-specific boost leak testers for Nissan.
Check the engine and year in the product name, or text us a photo of your setup and we'll point you to the right kit.
Both Nissan kits are twin turbo testers in billet aluminum, so you can pressurize both sides of the system at once. The R35 GT-R kit covers 2009 to 2018 cars and fits the 3" intakes. The Skyline R33 GT-R kit fits the stock RB26 inlets. Each kit comes with two end caps, a gauge and an air fitting. On twin turbo cars, a leak on one side can hide behind normal boost on the other, which shows up as uneven boost, a lean code or slow spool. Testing both turbos at the same time is the fastest way to find it. Start at 5 PSI and work up toward your normal boost, listening and spraying soapy water on the intercooler pipes, couplers and the recirculation valves. Running a different Nissan turbo setup, such as an SR20, a VQ swap or an upgraded single turbo? Measure the outside of your turbo inlet and pick a universal tester in that size.
