no chatter and not dumping!

[ollie ryan]

right, since fitting my K24 turbo setup i havnt been able to get it to bost right

when i accelerate the car pulls nicely to 3,000rpm and then it feels like it hits a wall and is really hesitant under boost until about 4.5k then it frees up and boost fine to 0.8bar like it should

but when i let off there is only a very very faint chatter and it will not dump for the bov

i asked a mechanic and he said it sould like a electriavl problem as it feels like a misfire

he has said to change the plugs and dizzy cap which i will be doing this week but surely if it was anything like that i would have my engine managment light on?

i have take everything on and off about 4times now all the intercooler is tight as can be

i had a new exhaust fitted last weekend and it also sound like a tractor so im guessing that is blowing slighty

anyone have any ideas or what to check for?

also been told it could be poston rings but im not burning any oil at all

[daz gt turbz]

you using an ebc mate?

[_shaun_]

what dv u got?

[iamlegend]

is the external waste gate 100% correct? i remember some one having issues and it leaded to that!

[ollie ryan]

no ebc at the mmoment

and i was using no dv until today i fitted a cheap one that i used to run and it workd fine then

waiting for a hks one to turn up

shorty came round and said my wategate is 100% correct

[ollie ryan]

also still running a standard ecu with fcd

and standard injectors and fuel pump

could it be a fueling issue?

[nazzurro19]

i had a really bad misfire and i didnt have my eml on so it could stil be a misfire

mine was at around 5k and it felt like i was hitting fuel cut an i turned my boost down haha turnsout it was just misfire lol

[Starlet__SR]

Blowing the spark out perhaps?

D

[ollie ryan]

Yeah I can clearly here the turbo spool,

And naz this feels like fuel cut, I will change the dizzy cap and plugs when my new parts arrive and see what happens

[ollie ryan]

just went for a drive after sorting the mani out

there is a slight hissing sound coming from the inlet manifold

when i had the new enigne fitted they didnt fit a new inlet mani gasket could this be the cause?

it hesitats badly between 3-4krpm and makes full boost just after 4k but still wont dump

[turbo Grant]

Try taking out the fcd. Might be fukin up your map sensor reading.

[ollie ryan]

how do i remove the fcd?

can i just literally remove it?

[Amjad]

TB or Inlet gasket? It's been an issue on some NAs..?

[ollie ryan]

anyway of checking if the tb is okay?

[Amjad]

I meant the TB gasket lol

Also TPS sensor or something? But then that's more to do with idle I think? Well it was for me

[ollie ryan]

right can anyone confirm that my wastegate is correct

i have it connect to the throttle body

blue pipe is the wastegate one and the black pipe was orrginally connected there but have just blocked it off

is that okay?

and conected to the side of the wastegate

[N80Jamie]

Try putting the black pipe back where it was on the TB then T piece the blue hose into the black. You may be blocking something off that your not supposed to be. I;m sure someone can confirm that though!

[ollie ryan]

okay mate will try that

i wast told that black pipe is to do with aircon?

[N80Jamie]

Im not too sure about that dude. I T pieced mine in on one of the thinner black lines on the top right of your picture. Mine seemed to work fine. Might as well give it a go, nothing to loose!

[ollie ryan]

okay cheers mate

will give that a go

[N80Jamie]

No worries, good luck!

[ollie ryan]

so today did what jamie said and still wont dump or chatter

also fitted a HKS dumpvalve so i no the dumpvalve is good

[ollie ryan]

any help please!

[ollie ryan]

anyone?

[ktl]

how come you havent connected the blue pipe to the turbo and gone for the inlet ? im guessing theres no t-off from the turbo ?

and if this problem has happend since you put your new turbo kit, you could possibly blame the wastegate/turbo
