Hey guys in need of a boost controller. Don't know allot about them but need one before my tune.

What are people on here running?

I hear the greddy is popular

I can get the blitz spec s for 100$ less then the greddy Profec b 2. Which one would be the way to go?

Thanks in advance

for $100 less go the blitz.

basically the same EBC.

I have the blitz spec 2 in my car and it holds 20 psi with about a 1.5psi drop around 6000-7000 revs

which TBH is fine by me at that rev range ;)

one thing that is important to remember regardless of what controller you use is that be careful and aware of the pressure difference between the actuator or gate spring and what you want to run

ie if you run 7psi spring and you want run 22psi thats a lot of work for any controller and the results might be spiking boost / tapering off boost or inconsistent

you should run a spring that suits your "mininmum possible boost" and then use a controller to let you bleed a few PSI over that mininmum

ie if you want 21 psi then run springs that give you say 17psi minimum and bleed the rest via controller

and lastly if you see boost pressure taper off in the rev range its probably excessive exhaust back pressure (housing too small or boost too high)

I had a profec B which was ok until you start running over 20 psi.

as per above - any controller can let you run any pressure

ie 57psi if you like providing the base spring level is half reasonable

it sounds like you might have had the wasgate spring too low, ie 7psi spring trying to bleed 20psi

and/or the housing is too small or exhaust back pressure is excessive

even with a 15psi spring a small housing can yield poor boost control as well or "tapering off boost" is what most people see

and they usually blame controller and try to find a better controller that can hold boost

ive got a powerfc boost kit for sale to suit ecr33 for cheap

If you have a power fc this would be my first choice, my second is a Gizzmo ebc, i have one and it works great and is not expensive because it is only an ebc, does not have any other wank factor attached, i would recommend almost any other ebc before a boost T or adjustable wastegate, the way an ebc works much better than any boost T.

Edited by W0rp3D

there are a few additional features the powerfc boost kit has over a seperate controller

1 - plug and play no extra wiring or controllers

2 - boost displayed on hand controller

3 - boost correction is enabled on the ecu

4 - safety fuel cut if boost exceeds target by 0.25kgcm2 - ie split vac lines

5 - you can use the boost reading in logging if used with datalogit to better tune boost build

With an ebc set up right you don't have to worry about boost creep or drop off, personally I have spent the money on an ebc as its more accurate than the old hks adjustable wastegate I had.

thanks for all the replies

I ended up going for a boost t as my tune was brought forward and it was the cheap alternative to the space in time I have

maybe one day ill end up with an ebc as ones you guys have recommended

@gtsttrk - boost levels between 12-14psi

Yeah mate just FYI for down the track any of those controllers would be fine for those levels of boost:)

EBC can't be beat for maximum power and drivability, but for small to moderate power increases, the Turbotech boost T does an amazing job given it's cost. Never spiked or failed me in any way and I've never heard a bad thing about them!

    • I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way
    • This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.
    • Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.
    • To be fair it's the other way around. 300kw is boring in a modern Golf or BMW. They are so competent / well-engineered / devoid of emotion that you have to go stupid fast to feel anything. Whereas the <300kw RB still makes all the right noises and it feels good to drive. Can pull off at the lights with the turbo whooshing and the blow-off pssshing and feel like the coolest kid on the block. Just don't look to the side where you'll see the bored housewifes in their shitbox Yaris/Corolla/Camry that kept up because you didn't go fast at all
    • 300kW is so boring in a Skyline, you'll get spanked by someone's mum's Golf with Alibaba pipes, and an email tune.
