Who has ran one of these with a 1bar actuator?

I had mine on the dyno with it and when it had absolutely no preload on the ball so I could freely blow through the bottom the lowest boost level I was able to achieve was ~19psi. Boost was then tailing off to 17.5psi; I assume due to not enough preload causing it to operate like a traditional bleeder.

On the std rb20 and rb25 actuators it was rock solid; held boost perfectly.

On a mates external gate setup with an 8psi spring it too was rock solid; just didn't like my stiff wastegate. :S

Im assuming the hole drilled was a tad too big and bleeding too much off.

The boost controller on ebay is here.

I bought one couple weeks ago. Easy to attach and use, great results on a close to stock setup. I upped from factory boost (5-7 psi) now running up to 11-12psi. Very happy! :unsure:

Hi guys i bought one of these and fitted it exactly like the pic and instructions says to...I find in second it will boost to about 5-7 but in third it spiked to 15 so i dropped right off the gas. Not sure if it would spike higher, to scared to find out. Anyone have a suggestion as to whats goin on???????

I had the same problem. Read my thread, might fix your problem.

interesting 1 for ya. i had my car on a mates dyno a while back. Got 179rwkw @11psi using one of these boost controllers. changed it over to a new turbosmart one just to see if any difference was made to output and got 186rwkw at 11psi.....

interesting huh.... can anyone shed some light on why this might have been??

hi guys just received an email from jrdsport to advise me i can upgrade from my manual boost controller to there dual stage kit.

This will apply to those who have both the turbotech or jrdsport manual boost controller, im thinking about getting it.

Here is the link for those who are interested.

The bloke selling them on ebay is ok to deal with, its cheap, easy (too easy) to install cause you dont need to buy anything else and it works. Installed mine about 3 days ago all seems to be ok so far, im happy with it.

Gee didnt think this would go on for 80 pages but i got mine about 10 months ago and havent had a problem good for bugger all cash

DOES ANYONE HAVE A PIC OF INSTALLATION ON A RB20

CHEERS

damn capslock...

Has anyone else had an issue of boost dropping off higher in the rev range?

Mine has been working fine for ages & i just came back from holidays and noticed it was dopping off about 1.5psi.

I've given the spring a slight stretch but it didn't seem to do anything.

My boost is set at 12psi and it hits it, but it drops down to 10.5psi.

I've done the exact same thing, back to back, with my car, without touching a thing. It's just how the dyno calcs to give minor changes.

I'm running one of these with a hks actuator and with almost no preload on the ball it makes around 15psi...with preload and adjusting it i get about 18psi with a 2-3 psi spike in 4th gear...i guess its because i'm using a longer hose with the valve and also because it is a mechanical system and it takes time to stabilize...

i use one, it works not much better than a turbosmart ball and spring in my opionion, yet much better than all bleed type (needle valves) ive seen, it works instead of bleeding off excess boost it restricts boost from getting to the actuator by blocking it off till it has enough pressure at the ball to push back the spring

    • Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)
    • Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D    
    • Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D  
    • Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.
    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
