I found a good cheap boost controller for $22!!!

Yes CEF11E is correct. It was difficult to tell by the pics but it appears that the nit is connected corerctly to the actuator but cannont clearly see if you have other barb connected to compressor side of turbo. I believe its in the way it is installed that is the problem, perhaps you have the wrong line at wrong point..

in relation to solenoid

[CEF11E]

From the picture i can see the solanoid is still connected. I would advise to disconnect it. As i have never seen under the bonnet of an r34 i cant see where all those connections are going.

if you wanted to test it and isolate the the problem.

1. look at the turbo compressor housing. these should be a hose coming off it connect this to the BOTTOM of the boost controller and leave the other side connected to the actuator as you have it.

[zymotic]

ok so controller to wastegate actuator con is ok.

where the T piece is the are 2 hoses con. The top one cons to the bottom of the solenoid.

The bottom T piece con connects to the turbo pipe (pipe beneath air intake pipe bout the same diam).The other pipe not con to the T piece comes from a silver pipe below and cons to the top of the solenoid.

The 3 pipes are all within that black platic sheath secured by plastic tie.

So with this in mind u say:

1. leave con from control to wastegate.

2. Disconect the top T piece con that goes to bottom solenoid con.

3. Connect bottom (thicker) T piece con to the controller directly (the one that goes to turbo pipe)

4. Disconnect the other pipe (from silver pipe below, not con to T piece) that goes to top of solenoid.

So basically take solenoid out of equation. Is this going to cause any problems? Thanks all for your patience just want to verify before I go out and do this. LOL I'll get there one day I hope!

lol mate i can make one for $9. u can get everything u need from a good hardware store...

[zymotic]

now peak holding at 650mmhg or 12.5 psi.

will dial this down to 11 or so psi peak/570mmhg.

1 mmHG = 0.0193 psi

Thanks fellas!

Finding the components is the easy part making them to precisley control boost is by far something else. A number of people have tried to copy without success and caused damage to engines.

If I give you all the materials to build a house can you build it right???

Any noticable differences after installing this controller zymotic?

I am going to be getting one of these for my 33 myself. Can anyone please post some picks or diagrams of it properly set up on a R33. Cheers.

[FATAZZ]

mine should be arriving tomorrow, i already have a blled valve in place,do i just remove that bleed valve and put this 1 in its place? i hope its that easy...???

[zymotic]

As other guys have said boosts earlier and holds very well and holds it in a stable manner. Basically, even on idle the boost guage does not sit near zero anymore its like 1/5 of the way up. Torque builds quickly making the turbo more usable = better average power. I only have this and K&N Panel and I've noticed a good difference in limited testing.

Working installation on R34 below. Happy to help as others have helped me, as u can see I had some dramas But all good now. Mmm perhaps I should plug up that T piece. Next step for me is full CES Racing zorst, should get the silver service taxi moving nicely.

[simark87]

Man that's satisfying seeing my creation under someone elses bonnet...

:wassup:

[CEF11E]

Glad u got it working man yes i would remove the "T" peice and block off that line but you have it installed correctly.

glad to help

[Cubes]

That would indicate you previously had a vacuum leak, idle and light throttle should sit under zero, moderate throttle should be zero plus.

[zymotic]

Yes could have exagerated that point in retrospect (guess i was excited at finally getting it working). I think that the guage does sit higher on idle than it used to though or am i just imaging this? Certainly easier to get that turbo whistle happening in either case. Think I might have to take it out tonight again, possibly up a few hills. All in the name of testing of course :kewl:

[Cubes]

It definitely gets boost on quicker, I noticed a nice difference on gear changes.

[blackrb20silvia]

i still say this is THE BEST boost controller i have ever seen i cant get over it

congradulations to simark87 for the design and engineering of the product

this is my hands down the most bang for buck i have bought for the car also 100% reliable and effective and safe

so if i have dialled in 15psi or 20psi thats all im going to get no more no less no spikes no shit

congratulations!!

[Chase-u]

just wanting to know how this would work with a twin turbo car? would you just use a T piece to join both internal gates and then into this boost controller? and will it handle that fine do you think?

thanks

[Nozila]

this makes me want to get rid of my ebc. is the special for the sau community still on simark?
