I can make you a bleed valve for about $20 and send it to you then just T it into the line between the turbo and the wastegate.

What it does is bleed off excess boost and stops the wastegate openign as soon and thus allowing more gas onto the turbine wheels and there for makes more boost.

For my boost i just disconnected the bottom hose on the boost solenoid and fitted a hose connector off a sprinkler system, then modified the size of the hole the air leaked out off. all up this cost me 50 cents and my boost is set at 10psi and never spikes, mind you i haven't done anything to my engine apart from exhaust and pod filter, maybe different for highly modded engines?

Yeh I use a bleed valve on mine with a different actuator as well that is heaps stiffer than the vg30 one. mine is filtered and also has a one way valve attached but really isn't necessary as it will not suck in that much air. I just wanted everyone to know that it is possible to distort fuel maps when fitted. I have a safc so it really doesn't matter anyway lol

Isn't it different for an R33? You are talking about an R32 right? I thought with an R33 you do the same thing but with the line to the boost solenoid...?

On a R33, its best to bypass the boost solenoid altogether. So tap the bleeder into a line going from intake piping (compressed side) to wastegate.

Also, for us non-fuel computer guys, it might be a good idea to recirculate air thats being bled off. That way, the ecu isn't fueling for air that isn't there and the engine doesn't run rich(er).

I have installed the valve in the line fromthe wastegate to air inlet pipe and have disconnected the solenoid valve, adjusted it up so my standard guage is nearly 3/4 now..approx 9psi..Made a nice difference in performance although i almost feel it cuts in a bit early....How far can l go safely..any suggestions....Considering +7 = 13.4psi..:burnout:

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I did a bit of googling, the color MCM used was Galaxy Grey from House of Kolor. This is actually a colour I picked out about ~10+ years ago (or more). This one is a stock BMW colour, I guess over the years I figured it was smart to get an OEM colour that was pretty common for all of those sensible reasons one can think of..

      Cleaning my wheels 😍

      By PranK · Posted

      I absolutely love having clean wheels and also totally love cleaning them. Its not as important to me to have a clean car exterior as it is to have clean wheels. So I bought a kit. I generally use different products for my wheels than anything else, so I thought I'd buy a proper kit and bucket to keep it all in. I got this one from Waxit. I also got the CQuartz wheel and plastic ceramic along with a bunch more application micro fibre pads as CQuartz never provide enough.  The kit was good, but as usual the big, long spongey thing didn't fit between my spokes, so I needed to use a detailing brush and a larger brush that I already owned (been doing this forever, the spokes on these wheels are frustrating.) I did a full clean with the wheel cleaner, it has an iron killing product in it, so I found that I could just use the cleaner and nothing else on the wheels. The tyre cleaner and handled brush were awesome. Made cleaning the tyres so easy. Once everything was clean, I decontaminated with isopropyl and applied the ceramic. Two coats. I bought 2 bottles as I have a lot of wheels to do, half of one bottle did two coats on these. The X5 has 20's so I reckon probably 3/4 on that. Then, for possibly the best part, the wheel cleaning kit comes with a tyre black applicator. But, this is possibly the greatest sponge of all time - its a great size, quite stiff and HAS A COVER! When you finish applying the black, you just put the cover back on! This is revolutionary, I normally have to try and find safe places to put my tyre black applicators as they are covered in silicone and tyre crap. Or, you use something which just falls apart. This applicator is the bee's knee's. Get one. It's worth it. The tyre black is also like a cream, its very thick but goes on really thin, its very easy to use with the applicator. Ayway, after a big clean, decontam, ceramic coat and tyre black the wheels went back on and they look awesome.   Thought I'd share.

      Haha. Good work. I feel some of your pain because I spent a bunch of time under my car over the period too. Probably nowhere near as much as you did. My happiness is similarly improved by obtaining a desired result though. Those side skirts are.....hecking. Very unfriendly for street and hoist. Sounds to me like you've made a cart that needs to be driven up only planks/blocks at a 2 post hoist, rather than trying to get it up onto a 4 poster. It's very pretty, by the way. Somewhat reminiscent of Marty's squid ink on SuperGramps - at least in the photos.

      ATTAKD 356mm Brake Kit for Nissan Skyline R34 GTT or R33 GTST (front)

      By Kinkstaah · Posted

      ATTAKD 356mm Brake Kit for R34 GTT or R33 GTST. Same brake kit as per here from JJ: https://justjap.com/products/attkd-brake-kit-nissan-skyline-r34-99-02?currency=AUD Can confirm these will bolt directly to a R33 GTST with 12mm bolts OR to a R34 GTT (which is what I had) with the supplied bolts and the collets for the 14mm bolt holes in the R34, which are included. Also included is a set of rotors and hats, as well as 2x brake pad sets. 1) DBA XP (street, hills) 2) Forza FR6 (track) These are radial mounted and bolt directly to R33/R34. You will need extended brake lines to avoid them being full stretch on lock - this is common for all BBK's with the bolt point being in the center. In my case I welded another stud about 25mm lower than the OEM one and retained stock lines and fittings. You'll want a BM57 BMC to get the most out of these. I speak from experience. $1800 (neg for SAU people), located SE Suburbs Melbourne.
