Hey all.

I need to know where YOU have your boost gauge vacuum line connected to on YOUR rb20det.

I have read heaps of different things on the interwebz so please don t just tell me to google it.

mine is connected at the back of the plenum. But i do not think i am getting the right reading. Which is why i want to know where YOURS is tapped into.

Also, do i need to run the boost line to the little black box that is stock with the rb20det or can i just go straight to the plenum ?

Ok answer me this.

I have no bov so I have "dose". I know that you can have the dose sound while not being in positive pressure. Like the boost gauge not hitting zero yet.

Because I have a t04e it takes ages to get boost. But shouldn my gauge read zero with just my foot flat even if the turbo is not making boost? I ask coz atm I rarely see it go past zero. But at the same time, at wot it slowly climbs to zero and I hardly see it there either

Sorry if this is confusing, I cant think of the best way to describe it

"Dose" is air bouncing off the compressor blades when you close the throttle valve. As long as the turbo is spinning air > shut throttle > air goes back onto the compressor > pigeon noises

WOT should read 0 vacuum. So yeah, you have some problems somewhere. On my car, standard gauge sits just above 0 while the engine is trying to spin past 2,000rpm (don't need WOT for it to that).

    • 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
