No Boost, Tried Everything!

**Sharkus29** · 10-23-2011, 12:49 PM

Hey guys, my GTR still isnt running any boost, wont go past zero on my boost gauge or on my profec. We thought it was a boost leak cause we boost leak tested it and found 3 leaks, one pretty major, fixed them all and the weirdest part is the car runs fine, drives fine, just no boost, im driving an NA RB26, we checked the turbos and their fine too.. Im literally mind F******. I dont get how the everything runs fine but the turbos wont spool. I dont know what else to do so if you guys know of anything at all that could help me with this i would greatly appreciate it. So please help me out on this guys i really want to get my GTR running good again before putting it away for winter. Thanks

Did you check the wastegates? Are they stuck open?

The air has to be going somewhere if your turbos are working.

Double check for leaks, wastegates as stated, and see if your BOVs are holding boost.

Pressure test your system with a compressor by blocking off your MAF entries and pressurizing through a hose, you'll hear right away where the air is going.
