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 ;)

    • Which manifold mate? Meanwhile......Mark is wondering how bonnet vents would look on the NC 🤣
    • Actually,  just remembered there should be info in the threads (somewhere) about swapping to a manual steering rack and deleting power steering all together. 
    • Also had a look at the Nissan JP website looks like the 400r has a slightly shorter ratio than than the regular V37 3.133 VS 2.937 which from a guy who has driven both 3.69 vs 4.11 ratios in the S15 is bugger all. Seems that the AUTO Z runs the same ratio as the 400R but can't find any info as to if its an open or LSD? More often than not the auto LSD is open
    • Do not replace the power steering lines with this stuff. If it's anything like the Chase Bays stuff it will leak and be worse than stock. The reason why the reservoir is on the LH/passenger side of the car is because that's just where the reservoir was most convenient to fit. Don't overthink this stuff. The intake/cold side of the engine is pretty busy on these cars. And again, the hardpipe is designed to be a janky power steering cooler. In theory you can replace it with a real power steering cooler but that's really only for track use where boiling the fluid is a distinct possibility. Start with the low pressure lines feeding the pump from the reservoir. Make sure there isn't a bunch of junk in the reservoir filter. Be careful to not get ATF all over the engine bay. I hate dealing with ATF spills, you can clean it up and the slightest crevice will still release more oil that can still drip over time. You also want to inspect for leaks before you make a mess and can't tell what happened. Most likely you have a leak somewhere that is allowing fluid out and air in. Failing that it's allowing air in but not fluid out. Only place I can really see that happening is on the low pressure side because the pump will pull a slight vacuum to draw fluid in. Everything after the pump is high pressure or lower pressure, approaching atmospheric by the time it returns to the reservoir.
    • I did a skidpan night at SMSP this week, it was much cheaper than $350. But yeah, you need to slap an LSD in that thing.  I put an OS Giken in the 370Z and it's f**king MARVELOUS even compared to Nissan's viscous LSD. So you're saying it's free now that it's a housing estate? 😂
