The backup nut is unnecesary because you will be running the turnbuckle spun down all the way clockwise to where the rod bottoms out inside the turnbuckle. I want you to bottom it out. If the flat is not vertical then just back it off a hair. The backup nut will not be needed as a place marking device in this case. In fact, it will get in the way of the desired specific turnbuckle location and desired overall actuator rod length.please.
Just try it my way and then you can always replace the nut later after we are done if it does not impede us from shortening the throw enough. I dont want to have to get mad and fly down there LOL.
Seriously, the stock actuator rod length and turnbuckle assembly only allow a couple threads of adjustment and I dont want the backup nut interfering because it will take up a couple threads of turnbuckle travel. I did one of these on Saturday and the backup nut interfered, although that was on an VIII turbo. But, I think they are about the same.

Well I tried playing with the actuator, didn't really make an appreciable difference to transient response, I figure I might need an 18psi actuator for that. TBH though I think it more to do with the inherent nature of a heavier rotating assembly and larger turbine. On that note, I swapped in the BBK Lite, and damn what a nice little turbo. The transition from off to on boost is much more linear, and transient response is much improved. Boost recovery is fast between shifts and how it pulls smoothly up into boost from under 3K in any gear is a feeling I've missed. It's still very controllable in terms of % throttle to % boost/power, but is more eager to come on boost that the full was - I like this more though, to me the full tended to feel a bit lethargic (I know this isn't the general consensus though).

Yeah the first drive when when I went boost tuning I just knew it felt right. I also fitted a JDM tarmac spec 8RS gearbox and the short, close ratio RS box/lite are a great match for each other. I'm running 24 psi (same as full) tapering to 22psi up top (1.5psi lower than the Full) and I'm down 15-20hp peak and ~6nm peak, but I've gained a lot of response and the feel the car has now is one I like better. As you said it seems it's just the 'right size' for my desires.
Glad you're liking the 3B, wish there was someone locally who had one. I think personally being that I'm real sensitive to lag and rotating assembly weight, with larger than stock turbines ball bearing would be the way to go for me or anyone looking for that quick transient response - it really changes how the entire car feels.

blackenedwings, do you have any track videos with the BBK-B BB? I actually recently bought mine upgraded from my BBK Full (JB) that has some wear/damage. Do you have a youtube channel? How much power and torque did you make for the track? What type of dyno for reference.
