Ok I have a bob stock R33 GTS-T (only mod being recently installed R34 SMIC)

I have a turbotech boost control & a boost gauge on its way to me in the mail & will be installing asap

Since car is basically stock i only want to run the std boost level (7psi) but all the time instead of the 5/7psi via the solanoid (which i will bypass completely)

Anyway i know there is a brass restrictor in the line from IC piping to t-peice

My question is should i leave this in or take it out? as turbotech is a kind of a restrictor itself

I have heard to get std boost using a turbotech you need to have screw wound right out & it is JUST hanging on so with restrictor out wouldn't it mean i would be able to screw Turbotech in a bit more thus being a bit more secure & stable & accurate?

Also re boost gauge...Is it simply a matter of putting a t-peice in the top vacuum line coming from that little black box on firewall on drivers side & bobs your uncle?

Cheers

re Boost guage Yes that is how you do it, it is pretty simple. Bob's not my uncle.. lol

Check http://www.skylinesaustralia.com/forums/in...howtopic=142207 for some pics of one way of putting a bleeder in.

i recently installed a turbotech boost controller n ripped out the old solenoid, just used the tube off the turbo and the 1 going in2 the cooler piping....

as for the boost gauge, i d/c the 1 in the cluster (its goes to the plenum), the 2 power cables, 1 u earth and other i just tapped into the accessories on my ciggy lighter

tip: may want to get ur boost controller on first n make sure it runs right be4 u install the boost controller (just so u dont overboost it)

hope that helps

i don't use the restrictor. holds 14psi pretty well.

i heard if you take it out spool up will be a bit slower as wastegate creep increases...makes sense in re to std form via solanoid bleed but using turbotech should not affect this as it will be restricting flow itself thus decreasing creep just as brass restictor does correct?

so u left restrictor in place? what boost you running & how does it hold in re to creep/spiking/tailing off in higher rpms?

cheers

yup.

and leaving the restrictor in means that the lowest pressure you can run is higher.

Legend! that's exactly the information i was after...I might take it out then as i dont want to run much more than 7psi since i have stock dump & exhaust & I heard that the minimum boost with a turbotech is around 8-9psi but i am guessing thats with the restictor still in place.

Cheers

the best way to adjust that valve closest to stock setting is to blow thru the bottom nipple and tighten the bolt to the point where u can just, with quite a bit of effort, get the air to go out the side nipple.

fitted turbotech last night...feels like a new car!!!

First pulled it apart & put flat side of spring to ball bearing...then wound it in til screw just put pressure on spring...on car this was 6psi holding all the way to redline

wound it in a bit more til i got to just on 9psi & it stays there but bleeds to either 8psi or just under in higher revs depending on which gear...does not spike at all except if say i knock it back to 2nd it jumps a touch but nothing crazy

one question why does the boost bleed off a touch in higher revs?

(FYI i have left restrictor in original line)

    • 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.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
