Just in the process of setting up my new turbo kit and most of it's fitted just upto the boost controller bit then dyno.

Do I have to run a dual stage boost controller if I have dual wastegate set up on my single turbo set up?

Also if it matters it's dual bov set up as well on hot side one on cold side.

What do you recommend running with a haltec boost controller wise for my set up?post-100589-14226160057598_thumb.jpg

"Dual stage" when it comes to boost controllers has no relevance to whether you have one or two wastegates. It's just 2 levels of boost control. You can use any boost controller you like to run 2 wastegates

Let's get this straight. You have 2 external wastegates, right? So, split exhaust manifold with 1 gate on each side of the manifold. Are these adjustable? If so, you will need to adjust the wastegates so that they are set to the same base pressure as each other before you start to try to control on top of that with a boost controller. Make sure you do that or shit will start to get unpleasant. If one wastegate is set much slacker than the other, then it will open up before the other one. Half of the engine will see higher backpressure than the other half, meaning higher exhaust temperature, more reversion back into the cylinder and potential tuning mayhem. The other half of the engine will be slacking off on holiday along for the ride. The split pulse turbo will be getting a strong push from half the engine and a sexy little blow in the ear from the other half. Not cool.

As to what boost controller to use. Literally ANY boost controller. Seeing as you're specifically asking about what to use with a Haltec....well, given that most Haltecs can do boost control from inside the ECU, then all you really need to provide is a suitable solenoid and set up the ECU to do it. Otherwise yo can use a bleeder or you can use an EBC from Apexi, HKS, Blitz, etc etc etc etc. The choices are near endless.

    • They see me rollin' they hatin'....... Took me most of the day to make the necessary mods to the mounts to make them fit the car.  Fortunately I was able to just use the mounts that came with the rotisserie. The rear ones are really secure, the front I feel i might reinforce a bit more as it doesn't seem like enough attachment to the vehicle. I'm sure it's fine but better to be safe than (extremely...) sorry.  I drilled and tapped thread into additional M12 holes to each car mount where it attaches to the rotisserie as an extra fail-safe. Without them the side to side movement is just restricted by the allen head pinch bolts, nothing actually goes though the beam. Does now! I still need to adjust the rotisserie to get the car centred in terms of centre of gravity. If it's too high or too low relative to the rotational centre line of the car, it will be like a turtle and roll onto its back or as it currently sits, I dont think I'd be able to rotate it as it sits as it needs to lift the whole car up as it rotates. Ain't happening... I'm going to be nervous as hell the first time I go to spin it on its side...    
    • Oh yes done this when the window started flopping around.  Turns out the guides that run along the rail chanel had crumbed way. Took off the door card and pulled out the window mech, then the window, which you have to pull out through the top. As said unbolt the guide rail and don't spend 30 minutes getting frustrated trying to find a way to slide it out upwards cause that don't frigging work. Drop it down and out through the door hole. All I did to repair it was slice some 10mm clear plastic tube, vertically, then screw it to the guide rail both sides. This tubing rolls inward on both sides and leaves a gap wide enough to hold the window. To finish all I did was lube the plastic tube with olive oil and Bob's your uncle . . . well if he has the operation he can be your Aunt ! !  10 bucks in plastic tube and another 5 minute job done again . . . . YEH BULLSH#T ! My love for Skylines knows no bounds !
    • So was there a solution to this problem? I’m having this issue now. 
    • not expensive, just irreplaceable if you don't go sub 60 at wakie in that thing people will start talking
    • I haven't replaced that, but I have had the doors apart on the r32 a couple of times The door skin will be held on by a combination of clips and bolts, just take it slowly and make sure all the sneaky hidden bolts are out Once the skin is off you should be able to pop that piece off pretty easily, looks like there are only 2 bolts holding it on
