i have just got a profec b2 and i installed it onto my r33 gtst, now i am having problems as it doesnt want to stop boosting at all. I have checked the boost lines and none of them are kinked. i am not sure which way the filter for the boost line into the back of the unit is supposed to be? and also the wires running from the black booster that connects to the intake and actuator the wires for the clip on the back of the unit in the car were off and im not sure which way they are supposed to be? could someone please help?

sounds like there has been a stuff up somewhere along the lines.....did u install it yourself or got a import garage to do it....if you have installed it yourself i suggest you take your car into a import specialist garage like boostworx, tilbrooks or somewhere like that...they are generally good with these types of things so wont hurt getting it checked out

ok cool will do was thinking of that cheers mate

I had this same problem with my contoller. I had it prof installed. Took it back and had it checked. Swaped control over for another. It was found to be the control itself.

if u installed it yourself, and wanna save some money before paying someone to find out what you did wrong.

then grab a copy of the manual from the above link and go over it and over it and over it untill you know it backwards

this is what i did when i had a problem with mine... although mine just turned out that i had incorrect settings on the unit.

D1 Garage has experience with these controllers. They use it on there personal cars as well.

Give them a call I am sure they will be able to sort you out.

      Nismo GT Pro LSD configurations

      By GTSBoy · Posted

      Well, the trouble with that ^^ is: The configuration shown is absolutely a 1-way, not a 1.5-way. There is no way that a 1.5-way can be said to offer LSD action only on acceleration. If Nismo cannot get that right, then it is impossible to believe their documentation. That ^ is not a 1.5 way setup. That is a 1-way.   And so now I have allowed all doubts to flourish and have gone back to look at the MotoIQ video. I originally made the mistake of believing him when he said "this is a 1.5-way" at the ~6:10 mark. Because what he did was take the gear assembly out of the 2-way opening and just rotate it one place to the left to drop it into the 1-way opening. When he dropped it in there, the cam was "backwards" compared to the correct orientation shown in all other photos of that config. The flat shold have been facing the 1° ramp side of the opening, not the 55° ramp side. And I thought, "gee that's cute", but I was concerned at the time, when he put the other ring back on, that the gap between the rings looked like it was wider then in the 2-way config. And then I said a lot of things in my long post on Tuesday that could only make sense if the guy from MotoIQ was correct about what he'd done. BUT... I have now done my homework. I grabbed a frame of the video with the 2-way config, and then grabbed another with the "1.5-way" config, snipped out the cam and opening of that frame and just pasted it direct on top of the 2-way config. I scaled it so that the triangular opening was almost exactly the same height in both. AND.... the gap between the plates is wider with the cam installed in the triangualr opening backwards. That is.... it cannot go together that way. There would be massive force on the plates all the time, if you could even reassemble it.  So, My statement on the matter? The Nismo diff is actually only a 2-way and 1-way. There is no 1.5-way option in it, regardless of what they say. Here's a photo of a real 1.5-way ramp opening from Cusco (along with the 1 way option). And the full set of 1 through 2 way options from their racing diff, which is not same-same as what we'd typically be using, but...the cams work the same. A little blurry, but it comes from this Cusco doc, which is quite helpful. AND.... Cusco do in fact do what I suggested would be sensible, which is to have rings that do 1 and 1.5, and 1.5 and 2. Separately.

      Well it wasn't as easy as I thought.... and it also wasn't in my original manual which I did end up finding. They discuss the process in the Nismo catalogue though and it requires slight machining. Page 145.  NISMO PARTS CATALOGUE 2020

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I'm an idiot, my intercooler is rated for 1000hp. I had clicked on the wrong product. Knowing the delta P would be nice, but I'm doubtful I'll do it. Now as for an EMAP, that would be great and I'll get around to it eventually but from my findings in my last post, I'm considering a turbo swap now.
