AGREED, the initial controler had the hole (one of me mates has got one of the origional ones) and latley it looks like he doesnt dril the holes no more. and well said cubes, thats exactly what happens when no hole is drilled.... so drill a hole if you dont have one and reep the benifits

this is a bit wierd, the last 65 pages states how good these perform, then in the last 5 pages, some of you say how crap they are until you drill a hole.

sounds to me you guys got no clue

we dont have a clue.. thats coming from a newbie that joined 3 months ago.. haha

anyway hopefully mark sent them today, havent got an email back from him yet :P but im sure hes swamped off his feet. so hope to see them soon. then ill do the testing :):huh:

one thing i have noticed since drillin the hole is that sometimes boost will only go to 10psi, other times will hit 15psi. Not sure whats goin on, seems to hit 15psi in 1,2nd gear but 3rd and 4th will only hit 10. I'm thinkin i might of drilled the hole a lil bit to far down and the hole is actually bleeding of the boost rather than the spring and ball bearing controllin the bleed rate.

might braze up the hole at work tommorrow and try drillin another one a lil further up.

i had a tear in one of my cooler joins (didnt know) i couldnt boost over 8psi no matter wat i did, even without gate connected it wouldnt go over 8 psi so i put one of these controllers on and it went to 12 psi no problem.

They must be a good controller if they can do that. Currently running 20 psi without a drama too

I just received my ball and spring type MBC brought from trademe.co.nz it appears to be exactly the same as the ones mark is selling, this also came with the hole already drilled in the side, will try it out tonight, cant wait.

Holycrap, all I can say is if you don't have one of these, THEN GET ONE. Turbo response is incredible now. I'm never going to touch that GFB Atomic Boost Controller again.

I feel like taking the day off work and go driving all day now hahaha

done.. dw.. i installed it like in the pic. i also found a HKS T-piece off the fuel reg.. and a Greddy guage sender.. ok thats irrelevant.

Test Car.. 1990 BNR32 allmighty GTR.. Nismo exhaust, chipped ECU and steel wheeled turbos..

w/hole controller:

Upon first driving i noticed i ended up on boost reversing out of my driveway.. doesnt happen with nissan solenoid..

power is usable from around 2500rpm and full boost just shy of 3000rpm. and little lag between changes.. little lag at all.. its quite amazing. on the highway 100kph @ 2600rpm boost builds quite easially and fully ther at 3000rpm+.

it is set lower than what i was running prior to the test. 3psi or so lower but the torque is greater and all out car feels far more responsive and quicker than the stock solenoid.. (i am using the standard guage) noticed bleed off at around 5000rpm and it fluxuates as u rev on..

W/O the hole controller:

when i put it on the GTR it was set slightly lower on boost than the hole controller. initial response is good feels just as torquey as the holed controller. during up shifts the boost drops a bit more than the hole controller but not enough to whipe my smile.. unlike the holed controller ther is no spiking according to the gauge. boost is available from2500rpm upwards and full boost just shy of 3000rpm.

verdict:

I need another test car as the GTR doesnt seem to lag as much due to the TT set up. i will install these on the R34 and S14a and let you knw how it goes.

so far the holed controller seems to have a little bit more response but not enough to notice on the GTR, but sacrifices are made with spiking in the higher rpm band.

Both holed and non-holed controllers feel just as good as each other on the GTR but as i said the lag is not that noticable on the GTR. all up it is a massive and i mean MASSIVE improvement over the Nissan solenoid.

This is the best pic i could take while driving on boost lol.

can someone confirm how much PSI is going through her?

i will set them both to the same boost and install the same controllers on the R34 which is the lag kind..

stay tuned kids. :happy:

Mark.

      Certainly. It is probably broken under the wire style clamp. At least that one is easier to get at than the front one.   Sounds like it isn't a major leak, I'd start with backing off the the water feed and return banjos into the turbos half a turn then tightening properly. Hardlines can still crack over time, either in the tube (particularly when turbos are changed if the banjo is siezed in the the tube) or at the brazed joins between the lines and the banjo fittings. A coolant system pressure test will reveal all. BTW you'd be able to get a sump without exchange, it will just cost more as they will have to source another stock one for the next customer. If you want to address the sump a much better option is something like this https://www.hioctanedirect.com/hi-octane-racing-sump-extension-nissan-rb26 that you weld in locally (and add the oil return fittings at the same time)

      Pretty sure you are thinking of the throwout bearing there (which you should change when you change your clutch), when they are worn they will get quieter if you put your foot on the clutch. An input shaft bearing is turning/noisy at all times.

      I’ll have more of a look into Recaros over the weekend. It’s taken me 2 days to figure out which Bride seats suit my application haha.

      I am aware of their presence, but the product page looked like that conversion will eliminate the AWD capability. Fact remains it's kind of a hassle to send my oil sump halfway around the world and buying an extra one is expensive and unnecessary. Before I go hat route I'd explore more local options.    Would you recommend I just pull the engine and renew as many things as possible since I'm already having problems with some leaks? Would have to get an engine crane first though.

      Are there any indicators that the vehicle is in limp mode?  Any dash light, or something.  Or is it just lack of acceleration?
