I have had mine for about a year now. It has always spiked about 1psi, then dropped back down. I was never worried as someone posted that was normal/ok. I actually got it on a dyno though, and that spike makes the fuel lean out heaps.

Also, to get 12psi on mine, the 'tap' is JUST gripping the thread. It is ridiculous how much thread it has. If I screw it in 1 turn, I hit 19psi.... have they fixed this in the new one?

Who on here has used these boost controllers on a dyno and watched boost/fuel ? Wondering if mine was stuffed from day 1... Should I buy another or go eletronic?

Cheers

Chris

I've had a tuner tell me not to buy an ebc, keep the one i've got because there great

mine spikes a tiny bit about half a psi when it hits full boost and even though my car drops off power at about 5800rpm the boost stays at 14psi all the way through and past redline, afr's stay fine. Yours sounds weird, mine is about in the middle of the thread and is cranking 14psi, so maybe its shagged?

Hi guys,

I have a r34 sedan gt-t. I have no idea about boost controller as i've never installed one before, perviously owning a v8 :sleep:. And i was going to ask you a BIIGGG favour if someone could send me a few pics of how you did it and where its installed, and if you could give me a few pointers on how to install it so i dont get full boost like one member with a r34 was on this forum. If you have a step by step method with a few pics that would be great.

Anyways, i appericiate your time, and if you could help me it would be great

Hope to hear from you guys soon. Cheers!

Thanks guys :)

It's real easy, should only take a couple of minutes to fit. I will try and take some pics tommorrow of mine (also a R34 GTT 4 door) but basically you just plumb in the bottom of the T on the MBC to the wastegate actuator (so you unplug that from the solenoid). Then you pull apart the "Y" shaped hose adapter already in the car and you plumb the other bit of the T on the MBC onto the tube that feed the turbo presure back to the solenoid (bypassing the solenoid altogether). Then you just gotta block of the other thick host that goes back to the BOV plumback pipe (I used a bolt and a cable tie).

Then you just have to adjust it. This is the point you need to be careful, minute changes to the screw changes boost a lot, and its easy to go from 8psi to 15psi by mistake (i did this for a billionth of a second hehe).

I recieved my controller today :) and installed it but have been quite dissapointed with the results :P . Boost comes on quite slowly when you put your foot down from low revs. Also i can't seem to get it to go over 10 - 11psi even with the controller turned in clockwise till it cant go any further. i looked inside and its got the ball and spring n everything but doesn't seem like its woking properly.

I installed it where my old turbosmart bleeder was directly in between the ic piping and the wastgate actuator which used to create boost a lot faster but laged on gear changes and spiked a lil. Something must be wrong with the controller yeh? any idea's? BTW the srew bit is in line with the line coming off the ic piping, as in the screw is perpendicular to the line running to the wastegate- is this correct? Anyone had this issue before or simular?

Any help would be great

Thanks

From your description, it sounds like you have it hooked up correctly.

Try taking it apart (don't lose the ball or spring) and make sure the spring isn't catching on the thread inside. I remember a few others having this issue.

I will give it another go, when my car comes back from being serviced. Does anyone know what way the spring is supposed to go? is the cut part supposed to be against the bolt or against the ball??

Ok got my car back and first thing i did was take the turbotech off and pull it apart. I couldn't really tell if the spring was catching as i just tipped the controller upside down to get the ball and spring out. Anyways i turned the spring around so that the flat part was against the ball - it was the other way when i got it, and carefully made sure the spring wasn't getting caught and voila! works great now holds 10psi goes up to about 11 or so at times but my car has always had terrible boost creep.

When i first took it apart and re-assmebled it something must have gotten stuck cos it was on unlimited boost i think and got to 15psi by 3000rpm till i totally freaked out... :thumbsup: Anyways problem fixed either turning the spring around fixed it and the spring was stuck or something but works great now. :O

oh sorry, read ur post/s wrong. I thought you took it apart... got your problem... posted in here, then you took it apart again and fixed it. I thought you buggered it the first time you took it apart... i didn't realise that this was AFTER you had the problem.

oh well... all good :D does yours have a little hold drilled in the top?

Oh i see, Yeh it was when i tried to fix it cos at first it wouldn't boost at all - as in it was turned all the way in and would just go to 6psi and slowly climb. so when i opened it up and put it back in it did the opposite! probably was gonna go to infinite boost cos it got to 15 before i though ohh sh#t. Anyways holds now, but one thing ive found though is there is quite a bit of lag on the gear changes. Anyone else experienced this? mine doesn't have the hole in the top, I'm assuming this is why?

      3D printing fun

      By Sean'O · Posted

      Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.

      When I was replacing my pump due to being stranded in the wrong state, I went with the Deatschwerks 320lph kit. It is a direct plug in to the stock wires, harness, everything. It comes with a plug... but you can plug the OEM plug directly into this thing. https://justjap.com/products/deatschwerks-dw300-fuel-pump-nissan-s13-silvia-r32-r33-r34-skyline-c34-stagea?currency=AUD Downside: Won't actually flow that much on boost if you want to push it on E85, but it's comparable to the 040/255 etc. Little more actually.
