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

[mike_a31]

u might only b able to get 0.7 bar as ur lowest due to the weight of the ball bearing and the spring resistsance still holding wastegate shut just that lil bit longer.

Just a guess.

[groper]

hey do i need 2 of these for a twin turbo rb26, or just the 1??? im ready to order...

[SS8_Gohan]

i think just the one... a guy with a r32 gtr a few pages back is loving his, and says it's going very well. He only ever seem to mention just putting 1 in.

[mike_a31]

It may seem strange but i was having problems with mine havin varied boost levels while driving, i have since then mounted the MBC vertical as b4 it was on its side kinda tucked down the back of the power steering resvoir. Since mounting it vertical i have noticed no more vaired boost levels, smashes straight up to 15psi and holds there strong.

I've got one of these boost controllers for about 3 months now, works excellent i don't notice any spikes either as long as you tightened the bolt at the top properly and make sure it's connected firmly it should be working fine.

i have it mounted vertically too.

but can you guys lower your boost level to .5 bar if u wish??

yes i can. on the last thread or 2 it holds perfectly at 7psi. got a R33

as i screw down more (although very sensitive... screwed down 2 rotations and it went up to 16 ) up the boost goes. such an amazing little peice of work .

i set mine to 9psi (no fmic yet) and it holds boost between gear changes(i.e when shifting at full boost it will only lower to about 6 or 7 then hit straight back up to 9), feels heaps smoother comming on to boost compared to my old gfb which was set at 10 and seemed very laggy. full credit to the guy who makes them. works perfect. (came with the the hole already drilled)

i documented the install from the GFB to the turbotech over 3 photos. (photos are massive 1600 x 1200, forgot to change the setting)

...... 74 pages?

this must be one tricky/useful little gizmo

Jake33- I had exactly the same boost controller as you (GFBs in black)

anyways i found that controller to spike heaps past a certain point. But then again that controller was hard to figure out which way to turn with the alen key..

Im now using this cheap 22 buck one.. Does the jon fine.. Set mine at 0.8bar.. Spikes to nearly 1 bar on cold days in 2nd gear if i push it..

Otherwise its pretty constant..

Have you guys earth the black wire? I heard it will help a bit with the smoothness when you spool up..

Overall im happy with the 22buck controller..

-----------

Quick question...

If you put the controller in the wrong way, it wont boost at all? Or you cant turn up the boost?

What happens?

Cheers

If you put this device in the wron way, the wastgate will not open. In other words not a good idea. Just remember pipe from the intercooler goes to the bottom of the device and the pipe from the side goes to the wastgate.

I have one of these boost controllers, it holds boost really well. I run 10 psi on the street and 12 psi for the track. With the piggy back computer I run it works really well.

Just disconnect the hoses to the stock bleeder altogether, hence no need to earth the black wire.

Ba Zing! thats what i did. im guessing thats sweet.

Has anyone else noticed some oily residue around the small hole on their turbotech? Whats causing this and is it something to be concerned about?

I am guessing that you probably don't have a catch can?

Does the boost controller line come off the intercooler pipe?

If you answered yes to the above question, then you would probably find that the intercooler pipes have a film of oil on them and that you are getting a fair amount of blow-by.
