Default Exploding turbocharger (bad thing to happen when trying to merge)

Well, it looks like the turbo blew on my car, while merging onto the highway the car started shuddering violently, while a squealing sound came from the engine compartment around where the turbo is. This followed immediately by the car bucking violently and a verity of unpleasant noises... So I assume its safe to say that the turbo blew up.

The car is completely stock aside from a Stromung exhaust, so this seems rather early for the turbo to fail (144,000 miles). My guess is the previous owner mustn't have been very diligent about keeping good oil in the car.

Anyway, I've been searching around for info on turbo rebuilds for this car and have come up relatively empty handed. Do any of you know what I'm likely to be in for regarding this? I have a nagging feeling this is going to be very, very expensive...

Default Remove MAF to turbo (turbo inlet) hose and have a look/spin the impeller to confirm.

Then start looking for a used K24 (stock) turbo. Not too expensive. (Rebuild would be expensive, if it is possible).

Default Mostly Agree

Grab the compressor wheel with thumb & forefinger and try to spin it.

I would not recommend a second hand turbo unless you knew the car it came from was not over-boosting it, and you knew what to look for. Usually getting a KKK shop to pull apart and check it out is cheap, ~1 hrs labour.

In reality rebuilding a KKK is actually very reasonable. Look here for <a href="http://www.turbodriven.com/en/products/findDistributor.aspx">list of approved dist</a>. Shop around.

But the alternatives e.g. GT2871/K26 (see 034efi) will cost around same as a new K26 and run just fine on stock software and definetly more interesting when you're ready to take it to next level.

Default Where did you hear that a GT2871/K26 would run fine on stock software?

I highly doubt this.

Default Ummm ... Because I have run my Gt3071 on stock software with stock boost controller

the compressor wheel is the same size. Only diff is the 30 has a larger turbine and takes longer to spool

Default Both the GT30 and GT28 have larger compressors than a K24, K26 and the RS2 and RS2 Comp.

the RS compressor diameter is 2.6 and the RS2 comp ids 2.7".

The GT28 is about 71mm which is 2.8" inches. larger. or the 76mm which is 3"

GT30 typically comes with a 3" compressor wheel.

Default Ok thanks, I'll have to look for a rebuilder then.

Right now the car is at the mechanic's so i cant have a look at it the turbo impeller. The breakdown happened near the shop so i was able to limp it there.

I guess i'll just wait and see what they say and go from there...

when you say longer spool time, is incresed turbo lag terribly noticeable?
