Should I Get A New Actuator

[DaveO74]

Hi Everyone,

I have been in talks with Stao from Hypergear (Very nice and helpfull guy) and am in the process of getting my RB25 Turbo highflowed with the ATR28G3 (450hp) kit. Stao has suggested to me that I probably should get his 14psi actuator as part of the kit which brings me to this question.

As I already have all the common mods on my 33 including an Greddy EMU and electronic boost controller am I correct in assuming that I will not need this extra part and just stick with the standard actuator because with my current setup I am already running 15psi@ 217rwkw with a stock turbo (I know, overboosted). I dont mind paying the $150 for the part if I need it but I'm a bit confused.

Can anybody clarify this for me.

Thanks

Anyone???

Yes, it keeps the wastegate completely closed for longer. You'll notice better response, more midrange and a better boost curve.

As above, you should aim for a wastegate spring rated as close to the boost level desired so that the EBC can maintain a better curve.

Thanks guys much apprieciated

Dave, we have HKS adjustable actuators in stock if you require one "here"

On all of the high flows we used to sell they are definitely beneficial when it comes to controlling boost pressures and spiking.

Even on standard turbo's the improvement is easily seen when running higher boost pressures.
