I know that smallbox is not great but as i said it will be for a limited time and iam not going to get crazy. But thanks...i just want to know if i can use that clutch and not have "problems" -
No no. The Audi boost controller was made from a Norgren (or equivalent) 1/4" pneumatics pressure regulator, a similar (looking) relief valve (to create the "gated" function to keep the boost off the actuator until wanted) and a check valve plumbed in parallel with those two, to relieve the boost back out of the wastegate line after the boost event was over. It was the inclusion of that check valve, used sort of "backwards" as a relief valve, that was the stroke of genius that made the rest of it work nice. The only reason I stoped using it was because it was like any other manual/pneumatic boost controller - it's settings changed from season to season. The Profec is much more consistent winter to summer. -
A couple of months of gentle driving will be fine. There is a risk that you will kill it. A heavy workout will probably kill 3rd gear. Continued use will wreck the input shaft bearing.

That's because R34 RB25DET is a pull clutch gearbox. I have that clutch, behind 25Neo, in front of R33 gearbox. I have brand new R34 turbo gearbox, in a box (cardboard) in the shed right now, and it will be getting used with the same engine and clutch, because I also have, in a much smaller box next to it, the front plate to convert the new box to push clutch.

Are you planning to ever come on boost with the RB25DET? The torque of the motor alone will break the little box. It's not a matter of if, it's when.
