Blown Turbo Propeller

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:

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      Coolant leak?

      By GTSBoy · Posted

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.

      Is it alright to top up with just another green coolant?
