Hello everybody, this just happened to me today. So haven't visited my tuner yet. But hope maybe someone here knows whats wrong.

Was driving, and hit the gas hard on high boost. Around 6500rpm it felt like i hit a wall and both waste gates closed. Limped back home, car wasn't making any boost at all and wouldn't rev past 4000rpm.

- Oil pressure is normal

- Engine temp also normal

- No crazy sounds or smoke

- No oil leakage

Car spec: Full tune GTR R33

- N1 Block

- Greddy T517z turbo's

- Hks F-Con 3.24

- Greddy Ebc

- High boost 1.4 bar, 600HP

- list goes on for few pages more...

At a guess. Boost leak. Probably partially blown a cooler pipe off. You should probably inspect all piping and check all clamps as a start.

What he said.

You running stock piping?

How old are the turbos? K's etc... only asking as i had the same problem when the rear one on my 32 let go, worst case senario though.

I would start with cooler and vac hoses aswell, then move onto manifold and turbo gaskets...

Turbo's are less than 3000km's old. And its not really a leak because there is totally no boost being made, so some hose must have gone off completely.

If a cooler hose partially popped off that is exactly what would happen. All boost is leaking out before it gets to manifold. 2nd scenario for no boost would be gates stuck open but that isn't going to stop it from revving over 4k and eventually it will build boost. 3rd scenario busted turbos.

Check the piping if u can't see anything obvious take it to an expert to diagnose.

So this all happened last night so went out today in the sun. My intercooler piping connecting to the intake manifold has completely gone off! Sadly can't put it back my self by force, so will have to go to my tuner. Point is how safe is it do drive like this, or should i tow it. Will be expensive but with a car worth €40.000 why not.

Lol i do, bot the piping must have moved. Can't cat it back to place, without getting the car on a lift and getting beneath! Believe me if i could get the pipe back by my delf i would do it!

You probably shouldn't own a GTR then lol:)

Don't have the tools you described, and sadly in Amsterdam our side roads are not straight. We don't have asfalt roads, the road is made out of small blocks. So jack stands would be very un safe. So a garage is needed.

You own a GTR and don't have a garage to put it in?

Thank the FSM I live in a place where we have plenty of room.

But just for clarity.....my driveway and parking area in front of my house and under my carport is paved with pattern pave concrete which is stamped with a cobblestone patter which is just as uneven as the cobblestones on your street. I still use chassis stands on that surface. I just use a piece of compressed fibre-cement sheet under the jackstand as a bigger spreader plate.

I have seen people working on cars in worse conditions than your city backstreet in places like Belarus, the sphincter of the universe, Israel, etc etc all the time. People make do with what they have. I would not own an old car like these without the tools necessary to do the bare minimum.

The sphincter of the universe is where exactly?

Imagine a bird that Americans eat at Thanksgiving and that we eat at Christmas. Now imagine a country of the same name that borders Greece, Bulgaria, Syria, Iraq, Iran and Armenia. That country and that bird, when typed into this forum, gets auto translated into "the sphincter of the universe". Ordinarily I think that's not quite quite fair, as there are other places in the list of borderng countries that are certainly a lot more sphincterish.....but anyway, at the moment I think it's fair enough and I wouldn't be too happy being in the southern part of that country like I was this time last year!

    • 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"
