Do a full exhaust first. The car will make more boost pressure by itself as it is taking away a restriction.

Upping the boost on a standard car won't give many gains as there are still large restrictions.

The vac line that doesn't connect to anything, Is that the line that the other end connects to the boost controller? Because if the controller has no idea what boost the car is running it wont be able to regulate it.

So you have 3 vac lines coming out of the little black box?

That hose needs to go back into intercooler piping. As stated it controls boost.

you can get an air nipple welded or a screw in type from like repco of sorts.

Im sure this has been discussed many types, search intercooler, nipple.

jacked thread here... soz :P

But there is already 1 vac line going to the plenum that should be all the controller needs to tell what boost pressure the car is running. Why would you need 2?

just rip all that crap out and connect one side of the boost controller to the wastegate on the turbo and go to autobahn or repco and grab a little brass bard fitting and screw it in the cross over pipe( will have to drill and tap it first) then plug the other sside of the boost controller onto your bard fitting and hey presto your done. go for a drive and set it at around 10- 11 psi on a stock setup. anymore and well we all know what happens. lol

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      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.
