i just bought a GTR and ill be pulling my EBC out of my GTSt to pu it into my GTR.

im not sure how to do it though.

there is 2 actuators for 2 turbos, so do i use a Y joiner to hook them both up to the solenoid? also im not sure where to hook it up to the FPR.

has any1 done it before? can you link pics?

cheers

yeah its pretty easy assuming you have the standard piping under the plenum.

the pressure source for the new solenoid is a vacuum pipe which is at the rear of the plenum (underneath) hook that to the input of the solenoid. the output of the solenoid goes to one of the 2 pipes under the plenum just above the oil filter (it comes from the standard boost controller). Not sure if it is the top or the bottom one off the top of my head - you need to trace it around the motor, it is the standard line that goes to both wastegates.

when you've done that you need to block 2 points in the standard pipes - the hose that you remove from the plenum needs to be blocked, and the other line that goes to the standard boost solenoid has to be dropped too.

this is the easiest way, you can retain all the standard piping and even mount the new solenoid where the factory one normally sits.

Im about to fit the same controller to my Autech Stagea. Pics would be a great help. so far ive spent nearly 4 hours searching the net for info on how to fit one of these to a GTR.....lol

will have 2nd attempt tomorrow at fitting it!

yeh its hard hey lol. unless i see some awesome pics ill be getting my mechanic to do it...

there is nothing on the net for the Greddy EBC into a gtr :dry:

you and me both man!!!!

FFS!

*takes a big deep breath

i sort of got a rough idea how to do it... just by tracing the vacum line from the wastegates of both turbos back around the plenum side of the engine but i lose sight of the line under the plenum lol....

its hopeless lol

sorry my next post went missing in the forum move. the top pipe of the 2 under the plenum is the one that goes straight to the wastgates. so give it a shot joeleo87

to make sure you have it right, turn the boost controller off (ie standard boost) pull 2nd gear on some open road, when you get to about 3500rpm if it goes over 14psi its not right....just get straight off the throttle if its wrong as long as you are paying attention everything will be fine.

so if its the wrong hose. it will just boost right up? and no damage whats so ever?

ill give it a go tonight duncan :(

if it works ill make a DIY!

um thats not quite what I meant.

If its wrong it will boost to eleventy billion - so if it goes past 14psi get straight off the throttle. If its wrong, and you keep your foot down you willl kill turbos and/or engine.

If its right it will stop at the right place and you will enjoy the extra boost :rolleyes:. make sure the controller is off when you test - this will mean you only get standard 12-14psi boost

i was thinking duncan, can i just replace the stock boost solenoid with the EBC 1?

or will that just poo things? to eleventy billion?

where do you hook up the unit's vacuum line? it says in the guide to connect it to the fuel pressure regulator? where might i find that?

photos would be a great help right now...

im lost :S

thats the ezy part man.

if you follow the fuel rail (where the injectors are) at the end (radiator side) you'll find the FPR, there will be a small hose coming off it going into the engine, you put the 'Y' connection :P

The ezy way is to just replace the stock boost controler valve. Its very simple an is just as effective. I did my 32 gtr this way any had not problems.

I have also tried it with the controler mounted on the passenger suspension tower with the hoses cut in near the actuator's. It's a lot harder to do and you have to be confident with removing the top turbo pipes to gain access.....

Also as a note to all tune all the setting on the sontroler right down and slowly adjust them up...I started at about 50% on all settings and it was way to high. Start at about 5% on everything and work your way up to your desired boost setting.

i just installed the vacuum line to the Fuel pressure regulator. Ive got a strange feeling that my car is already running 14psi.. even without the solenoid connected up to the main unit. I hope not, cos then i will be dissapointed after my tune...

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
