Turbo Blown, What Are My Options

[Sparky206]

Just took the r33 gtst to the shops and on the way back, went to boost and had a large cloud of grey smoke come out the back, and the car will no longer boost so im assuming my turbo has given up

Currently the car has minor mods, FMIC, 3inch exhaust and was running 10psi.

For a bit of scope, im happy with how the car preforms and am not looking for more power. Id prefer to maintain the early response the stock turbo gives, and not have to get a new ECU and tune. But im not against a minor power upgrade if the bang for buck is there.

So what are my options? New turbo or is a rebuild with steel wheel worth it?

What costs am i looking at?

Hypergear $900 awesome bang for buck

Link?

Is that rebuild or new?

Also been reading around about some people killing engines with the ceramic dust created when the turbo lets go, how probable is it that this could have happened? as i recall i gave it a punch at about 3500rpm and it let go instantly once it left vacuum, and i held it there long enough for me to look down and read the boost gauge at 0 before i backed off.

Cheapest and easiest way would be get a second hand stock turbo (see above ) because you won't have to modify anything to fit.

Having said that, you don't know how much life the new turbo has left in it.

If you dont want to get an ECU then there is no point getting anything else other than another stock turbo.

So i would suggest buying Garys stock one. You wont find better.

GT62 is the only way to go for you spark. Oh and i nearly forgot ditch the 25 and start with a real motor get a 2jz

Put a V8 in...

Or a stock turbo back on, or rebuilt with steel wheels at least

*update*

Well I've gone with the hypergear hi flow option, sent it off last week.

When i took the turbo off it was the shaft that had sheered off, flush with the seals. Few little gouge marks where the wheel had impacted the housing on the way out, but other than that nothing too major.

Got to thinking over the last week to where the shaft and wheel ended up, so it took the exhaust apart tonight and im glad i did.

Starting at the dump pipe, you can see a slight mark where the wheel has spiraled down the dump pipe, looking in the other end theres a solid yellowish mark where the wheels impacted, followed by lots of little mounds, kind of like when you throw a clump of dirt at concrete, except this time with ceramic. After that i found the majority of my exhaust wheel at the beginning of the cat, in about a million pieces.

But, there was no sign of the shaft which the wheel was connected too that sheered off. Im not too familiar with the setup of the stock internals, but i assumed that the shaft would have been metalic, and survived the trip down the dump pipe. There's no way it got through the cat, it wasnt damaged at all, and nothing bigger than a grain of rice is passing through there, so any idea where it could be? or am i wrong in presuming the shaft is metal, and it has infact blown up.

Also, there's a bit of mention on ingesting ceramic dust back into the cylinder, causing damage.

Is this likely to occur?

With the exhaust side being separate to the intake side, and the car accelerating at time of failure im having trouble to see how people have had this occur

Cheers guys, thanks for the informative replys so far
