Hey guys,

I recently destroyed my turbo due to abuse and too many hot stops. (learnt my lesson) anyways there are bits of the intake propeller (i think it is called an impeller) missing three pieces. two are about the size of a small corn flake so does anyone think they are in the intercooler? or in the engine? (if they are in the engine, how the F should i get it out?) The three piece is thin but longer than the others and my main concern they are sitting in a cynlinder grinding away?

Please tell me your opinions.............. feel free to abuse me for destorying a turbo p.s i destoryed a big end bearing before that doing doughnuts?

any thoughts would be awesome....

undo all of the intercooler piping and check for bits and debris

also remove the intercooler and shake it around to clear any loose bits

check all the way upto the throttle body

we saw an r33 smash its compressor wheel

and there were bits mashed up against the throttle body

Intercoolers act as a lovely expensive filter when turbo's crap themselves.... I would think its time for a new cooler mate... Unless you want to risk one little bit blowing through one day...

Also check the butterfly in the throttle body, good indication of injested crap is little score marks on the butterfly made by shit hitting it...

Definately buy a new cooler... At least thats what I did :P

dont need to buy a new cooler. ive blown 6 turbos and cooler is still perfect.

just clean it with heaps of pressure and get the bits of metal out.

flush your engine oil too cause small fragments would have most likely passed through the motor.

but u will know when this happens, my motor clunked for about 1-2 minutes after i blew the last turbo. noise went away. cars still purrs, i think im just lucky.

I'm going to check my intercooler soon too. I had the same thing happen. I never saw a hint of any debris anywhere in the intercooler piping, including throttle body, so I assume it might be pre-intercooler, or has already exited the engine. No signs of any motor damage. I drove around with the replacement turbo for 2-3 weeks before I opened the old turbo and found the compressor part missing.

Sorry, I'm not hijacking this other guys thread, but I was running 0.8bar (12psi) on an RB20DET for the 2.5years I've had it, and it let go in 1st gear turning at an intersection, just starting to build boost. I guess it had enough and decided to break the rear wheel, before chipping the compressor wheel. Was making 229HP@wheels.

I do not have the history prior to this, although, it seems as though the ECU and previous dyno runs done by former owner, indicate it had been running higher, like 0.9-1bar. Dyno graph indicates 249hp@wheels.

Hey guys, thanks for you input! i think i will pull the intercooler and all the piping off and do a search for those pieces. I was running a slide highflow 15 psi which dropped to 12 psi with a turbotech T b.controller. I was thinking about doing a diy compression test, oil flush with some cheap oil - good stuff after, change radiator coolant, flushed and cleaned lines for new turbo, and a INTERCOOLER and pipe search. I wil post the picture of the impeller.. i really appreciate the feedback..

thanks again... p.s could i some how look inside the cynlinders? check for bits?

everytime i see the word "propeller" makes me laugh.. lol funny shit

Are you sure that the turbo chipped during the failure? maybe something hit it earlier on and the engine allready ate up the propella pieces :banana:

    • If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.
    • Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.
    • Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
    • I've got MCA Blues on my V36 Skyline, and while I've managed to sort out issues with scrubbing/bottoming out by raising it a smidge and increasing the damping hardness, the rear end still sounds *super* noisy when driving on anything other than the flattest surface imaginable. It sounds like a small party of flamingos are just chatting away in the back, which makes me think there are several link points in the suspension contributing to the noise. Am I hearing dried out/worn bushings? None of it sounds like metal-on-metal, it sounds more like hard rubber squeaking on metal. It's been suggested that a bit of silicon spray on each bushing might quiet them down, but I'm not sure what material the current bushings are made of (probably factory, I imagine) and whether silicon spray will degrade that material.
    • The obvious answer here is get a ND2/3 RF with the Targa top. The red is nicer, too!
