    N54 blown turbo *pics inside*

    So here's what caused the "no boost" situation on my car a couple months ago. After some unfructuous troubleshooting (suspected a wastegate operating problem) the car would start to smoke blueish out of the exhaust. By then I figured it was a perfect time to put in RB Turbos Click here to enlargeSo when the shop pulled the stockers, here's what they found:

    Seems as if it ingested something that damaged the blades of the turbo...good choice to switch to RBs!

    Rear turbo, very common. Your intake tube came off and it sucked something in. We are shipping a bracket to positively hold the tube on with all our hybrids.

    Yes definitely looks like it chewed something up. Hard to imagine though how that could have happened. When chasing the supposed boost leak the circuit looked closed.

    Thankfully the car is running great right now and I already had gotten the RBs in the past summer. Perfect occasion to put them in. And without meth the tranny should hold up,although I'll have to get a newer tranny (Car is pre-03/07) to fully unlock the potential.

    Does it? Click here to enlarge RB's spool so much faster than OEM, no matter how much boost you run. Look how fast the vehicle builds boost, and how fast it revs. You expect an auto to handle this?:



    Nice troll bait post, masked as a question.

    If you're referring to that flash, I don't think there is any concrete evidence that it will do anything to preserve the trans when, the manufacturers input torque is exceeded by that much. Heck, it hasn't solved the 4th to 5th gear shift issues with the singles to my knowledge so far, nor provided faster acceleration times. Just changes shift feel, and gauge displays.

    You obviously have never owned RB's. They're actually a hair laggier than stock turbos. And as long as you're not brake boost launching the $#@! out of the car over and over, the transmission can hold up for quite a long time. Plus, they're cheap now. I think everyone here understands the phrase "pay to play".

    Oh, I also want this bracket. It always bothers me that the rear turbo intake tube is so loose. Easy DIY on the lift since that is easily accessible.

    Again, you have obviously never driven a 6AT with the Alpina flash so you are making baseless comments with no merit.

    I also have not driven a 6AT with the flash, but I'm not the one making comments on something that I've ever experienced

    Comments are based on Zero 6AT singles signing up for shift sector, and zero posts from the guy who promised to give us acceleration before and after data from the flash.

    The single turbos aren't the only N54's with 6ATs --- So the facts still remain, the Alpina flash offers a significant upgrade over the OEM Trans Software. Faster, smoother shifts, that give advance timing in EVERY gear. In addition, the 6ATs on Single Turbos have it easier than the 6ATs on RB Turbo/Vargas Stage 2-3s. Why? Because ST's create significantly less low end TQ (which as a protective measure, the trans software was forcing a flat lining of the timing to protect itself) than Twin Turbos.

    Wrong -- RBs have OEM like spool characteristics until ~4k RPMs where they get a power surge & you can really enjoy the raised boost.

    And at least my "troll bait" positively contributes to the community, you're just the annoying guy who thinks he knows everything but continues to spread misleading information that you're pulling out of your ass.

    I agree. @Turkeybaster115, what's your real problem? I've seen you post informative posts before and then go on a triad of full retard.

    Getting back to topic here, and to respond, Tony, I do not think this was the rear turbo in the OP's case. The way I figure is.. iirc, the actuator sits inside (toward engine block) on the front turbo while the rear has the actuator on the other side of the housing, toward the fender. I remember that the case because on stock turbos, we would get 'rattle'. To fix it (in my and some other's case) you just tighten up the rear actuator rod (front was too hard to access because it's tucked in) and the noise went away. Had to fab a custom tool for the job tho, lol. But maybe the picture is so close I am mistaken as to which side is the engine block.
