Fellow boosters! :) I fitted an R32gts-t wastegate actuater to my S2 (neo) Stagea 2day and hit 15psi with light throttle. I have read that the 32 act. holds 10psi. When I removed Neo act. I lined it up against the 32 act. and a steel wheel 33 turbo I have. The free length of all the act. is the same. The mounting point to w/gate flap on Neo measured the same as on the 33. I can't work out how I ended up with 15 psi. I am able to make Neo act. arm adjustable to screw up to 10-11 psi. Would there be more gain/ control buying atleast Jacar Boost controller? I did do a search to try and answer my question. Go the Stagea!!!!!!

The difference comes from the fact that the wastegate arms are welded on different angles from R32's to R33/34's. (as in, on the turbo, the little arm connected by the rod to the flap (wastegate))

You wont have much luck with an R32 actuator on a 33/34 turbo as it will just be on too much pretension, resulting in massive boosting like you are seeing. (I think, at least, that makes sense in my mind)

What you can do if you want to tighten your actuator spring is to drill a hole closer to the diaphram on the actuator rod, so you would have two holes next to each other, the stock one and a tighter one. The tighter hole, if right next to the stock one, will boost around the 9psi mark id estimate. This would be using the NEO actuator.

I have a drilled, r33 actuator on a turbo thats got an r32 actuator arm, and I boost around 9psi minimum.

THOUGH....honestly mate, Jaycar IEBC is the way to go... or at least just a "TurboTech"

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
