Kkr560 Problems / Questions About Its Internal Wastegate?

[BUKLUP]

Hey guys i recently bought a r33 gtst with a KKR560 internal gated turbo.

By reading some users comments on kkr they arnt the best? Ive just blown mine aswell.

What i would like to ask is the internal wastegate on this turbo is one ive never seen before. It looks to be welded up from factory and has no way or being incorperated into the dump pipe? The wastegate flap is unable to be plumbed into the exhaust by the looks of it? Also it looks to be welded up?

Thats the turbo as you can see the flap looks to have afew spot welds holding it shut?

Can anyone tell me how this turbo would control boost with it being welded shut or am i just missing something?

Any help would be greatly appreciated

Thanks

the wastegate flap is behind that, and merges into the turbo exhaust before the v-band

what to you mean blown? exhaust wheel smashed out? seal went, whats symptoms?

more details..... I here "my turbo is blown" a fair bit, usually its something else, poor install and/or leaking IC pipe etc

thanks mitchy that what i thought but without having the turbo off the car i assumed it was welded shut.

well i was driving and dropped it back from 3rd to 2nd and i heard a loud clap noise and there was quite abit of blue smoke out the exhaust i think the turbo has dropped the seals.

my car is the actual one on the otomoto websit the dyno chart is my r33 http://www.otomoto.com.au/kkr/KKR560.html but not running 22psi anymore. Its at 18psi

check cooler pipes, my have blown off

i would say you may of indeed blown seals, i saw a 2JZ send the exhaust turbine wheel into the cat, followed by lots of blue smoke.

KKR are dodgy from what i have read, however what i have read would lead me to beleive that they are reasonably safe at lower boost levels.

how many Ks has it done?

[BUKLUP]

its about a year old say about 20000kms on the turbo

i will check all ic pipes aswell

i have checked the turbo there is no oil in it or any shaft play. The car idles fine for 20seconds then up down up down.

I think it might be something else. Might be AFM? are the r33 ones common to play up?

When it happened i down shifted from 3rd to 2nd and i heard a loud "clap" sound followed by smoke out the exhaust and car when reving past 2.5k starts to splutter.

anyone know of what it could be?

[Mr. Untouchable]

sounds like pipe work to me. check you havent split any silicone and just double and triple check every clamping point from the compressor housing to the throttle body.

thanks pal and mr untouchable it was indeed the cooler pipe off the turbo!

thanks again guys!
