Hks Actuator Problem

I bought a HKS adjustable actuator from a trader on these forums to go with my Highflow and I have been trying to set it to 11psi until I can get my tune and it dosent seem to fit.

If you look at the following pics hopefully this will make some sense.

This is the new Highflow with the standard actuator(Modified to 14psi by Hypergear)

Now you will see on this Photo the distance from the bracket bolts to the wastegate pin is approx 150mm

This is the bracket for the HKS actuator which will have it set back a little closor to the Wastegate pin (approx 130mm)

Now one with the total lenght of the new actuator (approx 190mm)

You will see on this one that the adjustable shaft is only about 100mm long

Now I have come across an installation pdf on the web which states that to set the actuator at 0.8Bar or 11.60psi the total shaft length should be 123mm, but as you can probably see on the pictures it just dosent look like it will reach.

The only way that it looks like it will even come close to fitting is to have the shaft almost wound totally out in which the thread is only holding on by maybe 10mm and as such heaps of play.

Is it just me or have i been dudded??

Has anybody out there had this trouble before??

It may be a noob thing but it just dosent look right to me cause even if i wanted to set it at .5Bar (128mm) I cant even screw it down close to that. What can I do??

Fit the bracket first. if the rod is too long then just cut it short, with those adjustable actuators remember to pre-load about 3mms above the wastegate arm, pull and force in.

Also mark the factory wastegate bracket possition on the housing before you remove it. In case you have to put it back on, you need to put it back on where it was.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.

      Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
