Alright I have this weird problem and was starting to lean toward the turbo being bad so I took off the intake and spun the turbo by hand spins freely minimal shaft play back and forth. 0 up or down. Started the car with the intake off knowing that if my exhaust wheel was gone it wouldnt spin but sure enough it spun. Had some boost leaks that I had thought were my problem but have them takin care off just one very small leak right now wating on a new tclamp to fix it stripped mine out. Had posted this vid a few days ago but deleted it thinking I had fixed it when I fixed the leaks but it didnt.
A little history on the motor to I used to have it in my 13 and towards the end of that car it felt like somthing was holding me back big time. Just put it in my 14 and this is what Im dealing with. new tps set to .5v a ct. New maf and tried a bunch of stuff off my buddies rb20 o ya frogot to mention what motor it was well this is my rb20 with rb25 turbo and 20 wastgate witch is closed all the way checked.
And ignore the bad grammer Im just a simpleton :wan:. Any help would be greatly appreciated.
Notice how if I slowly open the throttle it builds boost and revs but if I open fast my intake makes like a gasp sound. And I think but not positive when it makes the gasp sound it also sounds like all my injectors stop clicking.
