R32 Gts-t W/gate Actuator

[skidkid]

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!!!!!!

Maybe the actuator springs have different tensions, causing the higher boost...

I would suggest you have piped it together the wrong way around and the wastegate actuator isnt working at all now which is why you are getting 15psi.

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"
