Fellow Skyliners,

Just wondering if any one has ever spun the rear wheel off their standard Turbo i've heard of this happening with the R33 series 2 turbos and R34GTT due to the ceramic rear wheel i've been running bout 12 psi for ages and just fitted a front mount in the last couple of weeks took her for a cruise tonight and noticed it was playin up a lil when i hit boost comin home it made a noisy pop noise and since that its runnin like a dog and not boostin at all pretty sure i've spun the rear wheel off but just wondering if any of you have done the same thing ive heard this is pretty common for a standard turbo runnig exesive boost but if any one has had the same syptoms/fate can you share your experiances with me

I will pull the turbo off on the week end to confirm what i think but whats your experiances with blown ceramic wheeled turbos guys???????

What part of the exhaust does the impeller end up getting court in? I do have a dump pipe, high flow cat and full 3'' exhaust any help appriciated.

Have you checked all the hoses???

Intercooler piping???

Sounds like an intercooler pipe or a hose has come off

Good luck :yes:

Had a quick check n have had a loose hose before you can still hear the turbo boostin but now boost is not present at all this time thats why im leaning towords the rear wheel spun off

Doesn't really sound like blown turbo, if you did blow it, it should just drive fine, but have no boost.

If the rear wheel was gone, you would not hear the turbo doing anything, because it wouldn't be doing anything.

Check AFM plug, close check over cooler hoses etc.

It doesn't sound (from your description) that the turbo has fully blown or else there would be no instance of flutter... I think it's something else... checked your hoses, wastegate connection and intercooler piping... would it be an engine problem perhaps?

Well my turbo shit it over the weekend, but it didn't shoot the wheel off, it completely seized. My car still runs perfectly, it is just very gutless.

If your turbo was missing the rear wheel, it would still run nicely, should be better than mine too as it doesn't have a wheel in the exhaust that isn't moving.

Either way, think about it, if there is no rear wheel, what is left to drive the compressor? If you can hear it spool, or you get any positive boost at all, your rear wheel is still there.

Man ive got nothin no boost no positive pressure at all thats why i reckon its got something to do with the turbo, that makes sense hey??

it does run, but like crap the motor that is but cant hear the turbo at all and boost gauge shows no positive boost what so ever

(- Boost , There's No Boost, No boost here)

how about you list your mods here and we can make some assumptions.

Running 12PSI (bleed valve)

Trust Pod Filter

Front mount cooler

Dump pipe

Hi Flow Cat

Full 3'' Exhust (with cannon)

every thing else in the way of the motor is standard series Two items i.e. standard ecu, pistons, rings etc

Oh my mistake, misread a few times and thought you said you could hear it spool and that it still boosted a little somehow? :yes:

Still, sounds a little odd that it would make it run like crap, unless R33s are different, mine still runs perfectly normally, it just chokes up at around 4000rpm, which yours shouldn't do as there would be nothing in the exhaust.

If you did lose the rear wheel, it will be stuck in the cat, so rip the dump off first and see if there's a wheel/bits of wheel in there.

G day mate how are ya

hey mate - if you get no fluttering sounds that means the turbo is not functioning at all - my mate's S15 had similiar situation - I think either your Turbo's disengaged itself (connection-wise) or it's blown. sorry to hear that mate, it sucks I know.

Yeah good thanks - after I got my old R33 GT-R wing damaged, I wanted something different and have stuck with the R34 Nismo Wing (without sides) on my R33 it looks tough as... so yeah, very happy with it.

let me know how you go mate...

ifs its running crappy, it could be running rich as well...does it make a rough sounds after 4500rpm?? lower the boost down to 7-8psi and go for a spin if its smoother , ur just running real rich.

also look at teh stock boost gauge, when u plant it , if it only sits on the vaccum side and not boost thats an indication that ur turbos gone

^^^ :P

SXY-33R: Bad luck with the turbo, have a look into the Sliding Performance highflows, heaps of people seem to be having good luck with them and pulling some pretty respectable numbers. And at under $1000, it's definitely worth a think about :mrt:

      new 1.5 LSD issues/concerns

      By JC71 · Posted

      sold listed as a Tomei LSD 1.5 Way For 1998+ Nissan Skyline ER34 25GT RB25DE w/Open R200 https://www.ebay.com/itm/174006114594?campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=&mkrid=711-53200-19255-0&loc_physical_ms=108689&loc_interest_ms=&campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=71883f2ccc571356e0a757bc7adfdde2&mkrid=710-53481-19255-0&loc_physical_ms=108689&loc_interest_ms= it went in like butter all gears, alignment, back lash etc, rotation and clearances correct, and if rolling all rotates smooth and free when coasting down road , clutch in or out over 10 mph smooth... its the binding, clunking and jerking from a stop that is most concerning, also seems like its going to tear the tires off in 10 miles of normal road driving.

      What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.

      new 1.5 LSD issues/concerns

      By JC71 · Posted

      looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
