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.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
