R33 Gtr Boost Problem! Help!

[StefanjR33]

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...

Best to call tuner, unless you know what you're doing, could do more damage than good.

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?

Halve, some of it is HKS. But if you mean full aftermarket (greddy) intake piping to the turbo? Then no. Thank for the replies, all input is welcome.

Boost leaks can be hard to spot. Make a plug and apply pressure to be sure.

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...

[StefanjR33]

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.

You don't own a screwdriver?

[StefanjR33]

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:)

[StefanjR33]

Thanks for your opinion, if your in Amsterdam your welcome to fix my problem that 3 people couldn't fix without a lift!

[GTSBoy]

Um, trolley jack, 2 chassis stands, 10mm socket for removing the undertray.

Et voila, access to everything. Lie on your back under the car. I do it all the time.

[StefanjR33]

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.

[GTSBoy]

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.

[Piggaz]

The sphincter of the universe is where exactly?

[GTSBoy]

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!

Ahhhhh

You guys seemed to have missed the user Barbs....Everything he said was pro T.urky It got very old very quick, hence it is forever known as the sphincter of the universe.
