Hey guys. I'm looking for some help on this please. The car usually runs around the 23 psi mark with no problems. It's like one day it was fine then took it out again and now it runs at a perfect 16 psi. Nothing unusual happened while driving either. The car still runs fine but at 16 instead of 23. Nothing was touched on the car or adjusted. I have taken it out a few more times since then and every time the same thing, 16 psi? Boost is controlled via a gizzmo ebc. The only thing I have tried is that I checked and re checked all joiners and clamps. I even changed a couple of silicone joiners that I felt may be suspect but still the same. Any help would be appreciated. Thanks.

Is it an internal or external gate setup? it could be running gate pressure if the EBC isn't working? Mine does that when it plays up....

It's running internal gate setup. I did think that the ebc may not be working but I can still hear the solenoid working its little heart out, so I assumed it should be working but I could be wrong.

Unplug the boost controller and see if it still boosts at 16 and feels the same.

If it does still boost at 16 then chances are your controller is not working so borrow a mates controller and test it.

Sounds like its just running off the gate rather then the controller

Turns out it was the EBC. After initially receiving a dodgy solinoid when I first bought the Gizzmo and now this, I have ordered a V2 turbotech. You've had two chances Gizzmo, now you can get stuffed.

At higher boost levels every psi is important so if your gunna go in the cheap with a manual valve make sure it's setup 100% as you don't want to lunch your motor by going cheap with boost control.....

In saying that I spent fkn heaps on a HKS controller and have issues so that kinda stuffs up my point a bit :/

Hi Mat. I've tried quite a few different manual controllers and I must say when these turbotech products came along, tried one and was amazed. I've currently whacked the original version back on for now so hopefully the V2 is even better. As for going the cheap I don't believe going cheap on the skyline it's just a bonus it's that price. They could of charged triple the price and I would still buy it.

I had the V1 and it was OK, it did tend to bleed off boost though... In saying that, they are a good bang for buck controller, have you got boost cuts etc setup in your ECU? Just for safety?

Mines setup so if the boost controller or gate fail for some reason it'll dump fuel in, pull timing out and then if I haven't backed off it will boost cut... So it's pretty safe ;)

      Question about BoV on RB25DET NEO

      By Murray_Calavera · Posted

      You've just discovered a really good reason to tell yourself, yes, I do need to buy an aftermarket ECU. Put the MAF in the bin. Slap in the new ECU and have a think about what turbo sounds you prefer.  Do you want a 90's style BOV wooosh? Do you want a hektik tsututututu?  Mate, can't go wrong. Just gotta get that ECU and the world is your oyster.

      Question about BoV on RB25DET NEO

      By Kapr · Posted

      Hi. Iam just curisou about this topic. I saw this video. It is about Greddy Type FV2. I know that BoVs are about that sound but how and when to use it? I read some topic here and from what i have understand on stock RB with MAF there will be some "problems" if you use this BoV? It vents the air in to the atmosphere and the MAF on stock car needs this air back in to the intake and not out? Or is it wrong? If so...i saw you can put some adaptor to circule air back...but does that not "loose" that sound? I saw another BoV from Turbosmart and it has two "exhaust" like ports? One is for the stock tubing for letting air back and one is for "sound" and let the air in the atmosphere? Can someone please explain? This is the Greddy one:  And this is the Turbosmart.     THANK YOU!! EDIT: So i read about this topic some more and i if i understand that correctly: That Greddy can function either like BoV or 100% Bypass valve? And that Turbosmart is what they called hybrid so you can adjust what and how many air can be vented out or back in? Is this right? THX!

      That dirty voltage drop is the culprit I suspect

      It's about time I start work on my sun tan. So I knocked up a few parts that will all combine together to become my new power steering reservoir. Now just to produce an abundance of UV and IR rays while melting a heap of bits of alu to become one... Well, that's after I put one more hole in it for the return line to plumb to. It likely won't be this weekend, as Sunday I'm meant to be in doing some last minute stuff to the AMG race car, and the weekend after will be filled with non my Skyline stuff, followed by Bathurst 6 hour. So I don't expect to get to melt metal for at least 3 weeks.   I also managed to stuff up and start cutting the hole for the res to pump pipe on the wrong side of the line... It means instead of the lines being nice and tight against the inner guard, they'll be out off the guard.    The size of it means I should end up with about 1.8L of power steering fluid, and still have space for another half a litre before it reaches the overflow/breather. This is wayyyyyyy more capacity than factory, which should help keep Powersteer oil temps lower, and the design hopefully allows it to prevent any aerated oil being able to makes its way down to the bottom as it'll have a couple of baffles and some hopeful trickery to force air bubbles away from the bottom.
