Blown td06

[Minaj]

Hey guys well i put my td06 back on which was replaced with a new core. I ran it it, while putting my foot down i was boosting 12psi and all off a sudden i lost all boost only shows 5psi on my boost controller any thoughts????

[lachlan]

whats the rest of the story ?

get a seperate boost gauge

[Minaj]

So story is i bought a new core for my turbo which was replaced by kinugawa. Put everything back together car still wont boost wastegate spring pressure so i took it for a blat on 12 psi while boosting, the boost when away and it felt NA i turned up 100% duty cycle still does 5psi nothing higher..

oil feed or drain blocked? you had a prob with the drain didnt you?

[Minaj]

Oil return pipe was short so replaced it with longer hose and it was allgood, but i dont know whats going on tbh

[Marky]

they dont die for the hell of it, my first thought is poor lubrication - either too much or too little oil getting in, or its not getting out properly

too much itd be smoking tho

what was the problem with the last one? or did you just bolt on new one and fang it

[lachlan]

is the turbo broke or there is problems with your install?

boost controller plumbed wrong ?

pull the line off the wastegate and take it for a drive and see if it will go over 5 . but be carefull coz its free boosting

given any consideration to the oil feed requirements between bb and journal turbos ?

I\'m running standard oil lines. It should be fine with the turbo but it\'s reccomended to upgrade them. The problem with last turbo was apparently shitty intake and little dirt and stuff hit the compressor wheel which turned out to be no in balance anymore

Boost controller is all wired up correctly, Yeah i tried that still wont go over 5 psi.

so its a boost leak then . . and major leak of metered air

I would start here : and ask how you fixed that

[Minaj]

Cant be manifold fixed all the leaks and used a fuck load of gasket glue lol

[Minaj]

If it was a boost leak, wouldnt it show on the gauge ?

Dont.

PM subierex I think it is pay him to have a look.

Whats the bet a lump of gasket shit has gone through the turbine and trashed it?

To put it bluntly:

Step 1: Stop using cheap parts, you\'re chasing the better part of 300kw, do you know about the modification triangle? Cheap, fast, reliable: choose 2

Step 2: Get the non-shit parts installed properly. If you need to use loads of gasket goo then the exhaust isn\'t fit for a Toyota Corolla, let alone a performance car.

[Minaj]

No i use a steel gasket 5 layers for all manifold and turbo, i only out gasket glue on the outside edge of the flanges no where near the inside of manifold

[lachlan]

no because your gauge shows the boost reaching the intake manifold . not the boost your turbo is pushing out .

hence even when you free boost it it still only gets 5 psi at the engine because the rest is escaping somewhere

i think your missing a few things here because it should be pretty straight forward to figure out

i think your car has a major meatware error

Took all hoses off my wastegate car was boosting 8psi on wastegate spring is at 7. somthing

[Minaj]

Update: Replaced a silone Joiner Tighten the nipples on wastegate as one was loose. Got the car to boost 19 psi max on 100 duty cycle 100% gain 100% sensitivity on gfb ebc. After a while boost would read 19 psi till 5500rpm and drop straight to 5psi at 6000rpm. Had a wrx pull up to me last night on the mway back home with my friend of my still ate him while shifting before 6000rpm. 5th and 6th gear ftw HAHAH, back to the point now..

[Minaj]

Also want to note that on 4.5psi the wastegate is opening, even though the spring pressure is at 7.25 psi. ???

[Minaj]

Update: Looks like the tial 38mm wastegate was faulty also a issue with intake where its sucking up. Never use to do this before i installed the headers.

[Pappu1]

good on u for sorting

[vorigan]

glad it sorted even though i told you all this stuff before

and oil feed and return only reflex on the issue if the turbo failed or smoked ( which i checked the turbo ) but it still makes boost thus another issue

If your getting up to 5500 and 6000 thousand in 5th n sixth gear you are goin a bit quick mate...

[Disruptz]

6000rpm in 5th is pretty much off the clock, no wonder things are breaking
