Hi guys.I currently have a turbosmart boost T ,one of the latest type with the ball and spring and was just wondering if a turbotech would be any better? I will be getting a retune soon with bigger injectors and z32 afm to go with my current turbo which is a apexi ax53b70p25.The common trend with these internal wastegate turbos is that they tend to drop a few pounds of boost towards redline. Cheers

there is a thread on here some where thats like 70 hundred pages long about the turbotech boost controller being the best so i brought one in short it was shit. i now have a turbosmart T and think it is heaps better.

I had a better boost curve running the Turbosmart than the blitz ebc I upgraded to, although the ebc does ramp on the boost a little quicker.

Either of these cheap manual regulator style controllers should do the job perfectly. If your boost curve still drops off it wont be the controller, more likely you would need a stronger wastegate actuator.

+1 to turbotech!

Had a GFB bleed installed set to 12psi,

then switched to a turbotech (just to test) and the car hit 12psi so much quicker then the GFB, ditched the GFB immediately.

turbotech will be my only manual bleed valve choice, other then that, EBC it is :)

Thanks for the replies guys. I think i will look into getting a stronger actuator to suit my turbo.Does anybody know if a hks or garrett actuator will fit my apexi turbo?The actuator on it is apparently a 12psi.Cheers.

Buy an EBC. The cheapness of skyline owners never ceases to amaze me. It is scrooge season though I suppose.

So do you believe an EBC will stop my boost dropping at high Rpm,cause if so that is all i'm looking for?

A decent electronic boost controller is always going to be better then a bleed valve if set up right.

Just Jap have the Blitz Dual SBC Spec R boost conrollers going for $599. Its not cheap but you will get great results....

here is my boost graph its holding 22psi with a 15psi actuator.

The actuator is doing most of the work in your setup, try that with a 7psi spring. I have the same Blitz unit, it wont hold boost any better than the Turbosmart as my actuator is blowing open.

The Turbosmart and Turbotech ones are not bleed valves, they are regulators that are run in line, just like an ebc. They are great if hooked up correctly, not just for tight arses.

and a turbotech is not a bleed valve. it's a ball and spring type that blocks the pressure to the actuator until desired boost is reached, at which point the pressure is passed through.

very simple. very effective. very cheap.

but it only holds one boost level throughout the rpm range, and isnt configurable in any other parameters, obviously.

so depending what you need. ebc may be better, or may be a waste of money.

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
